Welcome to our safety help page

Electric gates are classed as machines and can cause serious harm if not installed and maintained correctly by professional gate installers. This was tragically highlighted in June 2010 by the deaths of two young children trapped by powered gates in separate incidents less than one week apart.

Don't just take our word for it see the links below 



Due to the increase in calls, and the general concern from end users, We are pleased to announce that we are offering electric gate safety checks for both domestic and commercial users of electric automated gates barriers and roller shutter doors.


All automatic gate systems must by law be installed in compliance with the Machinery Directive MD2006/42/EC and supporting standards as highlighted by recent safety advisories from the Health and Safety Executive.

To aid manufacturers and installers in meeting the requirements for directive compliance, a product standard for gates, BS-EN13241-1, provides an umbrella platform for creating a compliant gate product.

      All testing is carried out in accordance with EN12453- Domestic, Industrial, Commercial

       Gates, Barriers, Garage Doors & Roller shutter doors

Simple checks

Simple checks to ensure that your automatic gate is safe

Swing Gates

  • Place a dustbin in the middle of the gate pathway where the gates close shut. The gate should not close when operated
  • Place a dustbin where the gates will move to open out onto. The gates should not move when operated
  • Push a dustbin towards the gate when it is opening.  The gate should stop and go back slightly
  • Push a dustbin toward the gate when it is closing.  The gate should stop and go back slightly
  • When the gate is opening, try to hold the gate at the leading edge.  The gate should be capable of being stopped with a light force
  • If the gate is opening against a wall place the bin against the wall. You should be able to remove the bin when the gate has opened

Sliding Gates

  • Place a dustbin in the middle of the gate pathway.  The gate should not close when operated
  • Place a dustbin behind the gates and press to open.  The gates should not move
  • Push a dustbin toward the gate when it is closing.  The gate should stop and go back slightly
  • When the gate is opening try to hold the gate at the leading edge.  The gate should be capable of being stopped with a light force
  • If the gate has a paling infill push a stick between the gates. The gate should stop when the stick comes into contact with the support posts from any position

The guidance and recommendations issued by Gate Safe represents our interpretation of advice provided by a number of sources.  Gate Safe aims to clarify the key safety priorities relating to automated gate safety and to establish a protocol which represents the ultimate standard for best practice'

  • A total of 27 tests must be carried out on each motorised gate system.
  •  barrier safety testing   
  • Vertical measurements are taken from 50mm from the bottom, 300mm from the top & halfway up the gate (up to a height of 2.5m).
    force test
  • Distances from the closing position of the gate are measure at 50mm, 300mm & 500mm
  • gate test
  • Each measurement is taken 3 times and the average is recorded.

  • gate safety testing
  • If the average test result for the closing position exceeds 400N in force, the motorised gate fails and an appropriate safety device should be fitted to the gate- the test must be repeated.
  • The test is repeated for the opening phase of the gate if an obstruction (wall, fence) is within 500mm of the gates fully opening position.
  • If the average test result for the opening phase exceeds 400N in force, the motorised gate fails and an appropriate safety device should be fitted to the gate- the test must be repeated.
  • The current British Safety Standards are as follows:

    BS EN 12453:2001 Requirements

    BS EN 12445:2001 Test Methods

    BS EN 12636:2002 Installation & Use

    BS EN 12604:2000 Mechanical aspects


Automatic gates like all other moving machinery have to conform to the machinery directive legislation. This legislation states that manufacturers of machinery must assess the risks presented to users of their equipment and take all practical steps to mitigate these risks. The state-of-the-art for automatic gates is defined in the British Standard    BS-EN13241-1. This is an umbrella standard which refers to various other British/EN standards including:

en testing gate automation west midlands

The first step in beginning a new installation of bringing an existing installation of safety standards is the risk assessment. The installation needs to be examined and any possible causes of injury recorded. It is then possible to begin shooting the methods that will be taken to remove or mitigate these risks. these methods can be simple such as a small raiding panel to stop children from reaching a sliding gate motor or sophisticated such as a radar system that shuts down the equipment when anybody enters the danger area.


 The most common methods used are


 Safety by design :

Eliminating a hazard by redesigning the installation for example using hinges that do not lead to a change in the size of gap between the end of the gate and post it is hanging off.


 Infrared safety beams :

 Beams of light shining across the gateway to detect when an obstacle is entering the danger zone at the gate.


 Pressure sensitive ribs :

 Strips of a soft rubber material that detect when anything comes into contact with them. Often used on gates or the posts they close up to stop the gates from crushing anything.


Force limitation on motors :

 Electronic devices within the motor itself that allow the motor to detect when an unusually high level of force is needed to move the gate and stop.

The most frequently asked questions on European standards and directives for motorised doors and gates and answers from UNAC

1- What is CE marking?
It is certification, by the producer, of conformity of the product  to the applicable EC directives. It is not to be considered a quality mark.

2- Is CE marking compulsory?
Yes - for products which come within the sphere of application  of a specific directive implemented in Italian legislation. Thus it is compulsory,  for example, for products to which the Machinery Directive is applicable.

3- Which EC directives are applicable to motorised doors and gates  or to their components?
The directives applicable to motorised doors and gates are:
• Machinery Directive (89/392/EEC)
• Construction Products Directive (89/106/EEC)
  The following directives are applicable to the components, according to the  various types:
• Electromagnetic Compatibility Directive (89/336/EEC)
• Low Voltage Directive (73/23/EEC)
• R&TTE Directive (1999/5/EEC):  concernin radio equipment and telecommunications  terminals

4- What is the difference between CE marking and quality marks  (Nemko, ICIM, IMQ, etc.)?
CE marking is laid down by law, is compulsory, affixed by the  manufacturer and indicates observance of the essential requirements contained  in the directives. Voluntary marks indicate conformity to safety and working  standards, ascertained by independent outside organisations after a series  of tests and checks. Affixing the quality mark entails control of production  by the outside organisation. These marks provide retailers, installers and  users with a guarantee of the safety and quality of the products and are recognised  in major industrialised countries.

5- Can the voluntary marks and CE marking be placed on the same  product?
Yes, provided they are fully distinct from each other to avoid  confusion.

6- Who is responsible for affixing CE marking?
The manufacturer, importer or whoever places the product on the  European market.

7- Where is the CE marking found?
The CE marking must be affixed where it is visible, easy to read  and indelible.
• on the machine according to the Machinery Directive
• on the electrical equipment


or, where this is not possible, on the precautions  or warranty certificate, according to the Low Voltage Directive
• on the appliance, instructions for use or, as an alternative to the instructions,  on the warranty coupon and, optionally, on the packing, according to the Electromagnetic  Compatibility Directive
• on the product, according to the R&TTE Directive. According to the various  cases it must be accompanied by the symbol (!) and/or the number of the notified  body.

8- If a product comes under several directives must it have several  CE markings?
No, one single CE marking is sufficient for indicating conformity of the product to all the applicable directives.

9- Are retailers and/or installers responsible for the CE marking    not being affixed on products which they purchase and/or sell?
Yes. Before purchasing a product the retailers and/or installers  must check that the CE marking is there. Otherwise national legislation lays down specific penalties.

10- Who is the manufacturer of the motorised door/gate?

The person who supplies the motorised door/gate or            who "motorises" an existing manual door/gate. In all cases the manufacturer            must affix the CE marking on the motorised door/gate, assuming responsibility            for the manufacture of the "machine".

11- When did Presidential Decree no. 459/96 (implementation            of the Machinery Directive) come into force in Italy?             
Italian Presidential Decree no. 459 of 24 July 1996              made application in Italy of the Machinery Directive 89/392 EEC              and subsequent amendments compulsory. The Decree, published in              the ordinary supplement to the Official Gazette no. 209 of 6 September              1996, came into force on 21 September 1996.

12- What is the responsibility of those who carry out            work on a system brought into service before the coming into force            of Presidential Decree no. 459/96?              
According to  Italy Presidential Decree no. 459/96,              routine and unscheduled maintenance does not entail application              of the Machinery Directive to a product already in operation prior              to 21 September 1996. Vice versa, if operations which are not part              of routine and unscheduled maintenance are carried out, the work              is seen as construction of a new machine and therefore Presidential              Decree no. 459/96 should be applied. A recent Italian law (no.              62 of 18 April 2005), that amends Decree Law no. 626 of 19 September              1994 and is applicable in workplaces, basically lays down that,              by 11 November 2005, employers must align all working equipment              with the minimum safety requirements.  See also FAQ nos. 13, 14              and 64.

13- What should be done if changes have to be made to            a system brought into service after the coming into force of Presidential            Decree no. 459/96 and which does not observe the Machinery Directive?             
The owner of the system has to be informed of the              installer's and his own civil and criminal liability arising from              failure to observe the law.  Before carrying out any work on the              system, it has to be aligned with the essential safety requirements              laid down by law.

14- Is the maintenance technician who performs repairs            on a component without CE marking bound to affix it?             
It is not the duty of the maintenance operative to              affix the CE marking on the components and the finished door/gate.              When necessary, the components must be replaced with others with              identical functions and specifications. The use of different components              could be seen as a modification to the machine and therefore requires              its alignment with the laws/standards in force at the time of the              modification. The only exception regards the radio controls operating              at frequencies currently assigned to other services. In this case              it is necessary to replace the products with others that use permitted              frequencies.
               See also FAQ no. 62.

15- If, for various reasons, the client does not want            to install the safety devices, what should be done?             
UNAC recommends refusing the job after having informed              the client in full of the risks incurred.

16- Is there the possibility of obtaining a discharge            document for installation or work on a system not complying with            standards?             
There is no possibility of obtaining any discharge              pursuant to both Presidential Decree no. 459/96 and Law no. 46/90;              Art. 7: "Installer firms are bound to produce systems to standard,              using for this purpose materials also manufactured to standard".

17- Must each machine have a plate with the CE marking?            What must be written on the plate?             
Yes, as Attachment I to Presidential Decree no. 459/96              states: "each machine must bear, legibly and indelibly, at              least the following information:  name and address of manufacturer,              CE marking, designation of series or type, possibly the serial              number, year of manufacture".

18- Which obligations arise from application of the Machinery            Directive?             
In order to assist the installer in fulfilling the              obligations arising from application of the Machinery Directory              to motorised doors and gates, UNAC has drafted "Guidelines for              the installation of motorised doors and gates in accordance with              Machinery Directive 98/37/EEC and the standards EN 12453 and EN              12445", containing a guided outline for evaluating risks. The document,              produced by experts from UNAC firms, was devised              to facilitate the task of installers and is a tool aimed at informing              those in the trade of the content of the Machinery Directive and              the new European standards.

19- Do the risks listed in the UNAC guidelines correspond            to those stated in the Machinery Directive?             
The risks considered in the UNAC guidelines correspond              to those stated in the European standards EN 12453 and EN 12445              regarding safety in the use of motorised gates and doors. Although              this guide was drafted with the utmost care by technical staff              from UNAC firms, it might not include all the              risks which may occur in each particular installation. Therefore              the manufacturer of the "machine" is still responsible for completing              or aligning analysis of the risks indicated in the guidelines.

20- How must the user be informed of the residual risks            of the machine?             
Accurate information of the residual risks existing              in the "machine" must be provided via a document to be consigned              to the user (user manual, proof book, etc.).

21- Can there be several risks for the same area indicated            in the assembly drawings of the doors and gates included in the UNAC            guidelines? How must these areas be protected?             
Yes, there may be several risks in the same area,              which should be protected individually or as a whole. The indications              contained in the UNAC guidelines can be of effective assistance              in locating them.

22- Where can the standards mentioned in the UNAC guidelines            be found?             
All the standards can be consulted free of charge              or purchased from the sales outlets of UNI, the Italian standards              body, (tel. 02 70024200 - www.uni.com) and those of the CEI, Italian              electrotechnical committee, (tel. 02 210061 - www.ceiweb.it).

23- Who should be issued with the technical file?
            The technical file has to be drawn up and kept by the manufacturer            of the "machine" for at least 10 years from the date of manufacture            (date of installation of the motorised door or gate) and should be            made available to the relevant authorities when required.

24- What should be the qualification of those who issue            the declaration of conformity pursuant to the Machinery Directive?
The declaration of conformity is the formal assumption of            responsibility by the manufacturer of the conformity of the machine            to the requirements laid down by the applicable directives. It must            be signed by the legal representative of the company or by a person            with power of attorney from a notary public for signing the declaration.

25- Is it obligatory to consign a copy of the Declaration            of Conformity of the motorised door/gate to the owner?
Yes! The declaration should be kept in the technical file            and a copy must be given to the owner.

26- If someone purchases from a supermarket a kit for            automating a gate, to be installed for private use, must he or she            draft the Technical File and declaration of conformity and affix            the CE marking on the gate?
Yes, pursuant to the Machinery Directive. This does not            include automation systems for garage doors for domestic use in individual            homes and with non-automatic control if the producer of the automation            kit declares that it meets the requirements of the standard EN 60335-2-95            in full.
27- Are the procedures for certifying conformity to the Construction      Products Directive applicable to motorised doors and gates?
The standard EN13241-1 (harmonised standard according to the  Construction Products Directive and Machinery Directive) was published in the  Official Journal of the European Union C 67/7 of 17 March 2004. 1 May 2004  marked the start of the transition period during which application was voluntary.  Application has been compulsory from 1 May 2005.
28- To which products does the standard EN13241-1 apply?
It applies to all types of doors and gates, both manual  and motorised, used for the transit of persons and vehicles, in industrial,  commercial and residential environments. The term "door" refers to all types  of doors and gates, up-and-over or sectional doors, gates, road barriers, shutters  etc. The exclusions cover manual pedestrian doors smaller than 6.25m2, motorised  pedestrian doors (dealt with by prEN 12650-1); fire doors (dealt with by prEN  13241-2) and barriers used solely for vehicle transit.
29- What are the main requirements of the standard EN13241-1?
The standard specifies the safety and performance requirements  of the doors and gates, it lays down that the producer must declare these specifications  and it requires the performance of tests to demonstrate these specifications  (some with the intervention of a notified body). It also lays down that the  producer must control production to ensure that the performances measured on  the test specimens are maintained in current production.
30- Does the standard EN13241-1 apply to automatic devices?
No, none of the requirements applies directly to automatic devices.  However in some cases they are directly involved.
31- What is the notified body?
The standard EN13241-1 provides for the procedures for certifying the conformity of industrial, commercial and garage doors and gates to be performed according to "system 3", as defined in the Construction Products Directive. System 3 requires a "notified body" for the initial type tests of the product.  The notified body is a third party, typically a test laboratory, that has obtained (in Italy) from the "Ministry for Production" notification and qualification for EC certification pursuant to directive 89/106/EEC (Construction Products Directive).

32- If an accident occurs for reasons which do not depend on      the manufacturer, is the latter no longer responsible? Is insurance provided      for the manufacturer?
The manufacturer is always responsible, according to the provisions  of current laws, for own work. Otherwise the blame or omission of the manufacturer  can only be ascertained at the end of the inquiry into the accident. Clearly,  if no fault is ascertained, there will be no consequences for the manufacturer.  The manufacturer can stipulate a contract which transfers to an insurance company  the risks arising from civil law consequences (civil liability) of accidents  for which he is to blame.

33- For how long is the manufacturer responsible for the system?
The contract of works, which governs relations between the installer/maintenance  technician and the client, provides, in favour of the latter, action for non-conformity  and defects which is set at two years from the date of consignment of the work  (Art. 1667 Italian Civil Code). As regards liability for damages caused by  defective products, the manufacturer is liable for a period of 10 years from the date of manufacture (date of installation of the door/gate).

34- Is maintenance compulsory? Who is responsible for the failure    to carry out maintenance?
Maintenance of machinery, including therefore automatic gates  and doors, has to be carried out according to the indications by the manufacturer  in the relevant maintenance schedule. Maintenance is to be performed by the  owner who becomes liable for accidents and damage due to faulty or lack of  maintenance.  UNAC recommends the provision and implementation of a maintenance  schedule, according to the instructions in the maintenance manual and the indications  of the standard EN 12635. In the systems of buildings where Decree Law no.  626/94 applies, maintenance of machinery is compulsory. 
  See also FAQ no. 64.

35- Should the system be produced by several persons, who is the    manufacturer and hence responsible for the system?
There must in all cases be a "project manager" who takes on the  task of issuing the EC declaration of conformity and is therefore responsible for the automatic gate.

36- Is observance of the European standards EN 12453 - EN 12445      compulsory?
As with most standards, they are not strictly compulsory. UNAC recommends  application of EN 12453 and EN 12445 in that they allow a declaration of presumed  conformity to the European Directives. Otherwise observance of the requirements  of the Directives has to be demonstrated.

37- Are there penalties for those who do not observe the standard?
There are no penalties for those do not observe the voluntary  standards, but instead for those who do not observe the European Directives.

38- If safety of the motorised door or gate is achieved by restricting  the operating forces, should the forces be measured in each installation?
Yes. It is necessary to check, on each system, the actual operating  forces (linked to the specific features of the installation itself:  weight,  speed, friction, regulations, safety devices, etc.).

39- Is it always necessary to measure the forces?
No. It is not necessary in the case of installations actuated  by hold-to-run control or with type E safety devices that prevent contact with  the moving door in all situations.

40 - Can the manufacturer of the drive units carry out the force  tests on the sample gate in the most disadvantageous working conditions and  give the installer instructions on how to set the parameters, for example in  the installation manuals, exempting him from measuring the operating forces  of the gate?
No, since it is not possible to demonstrate that the results  of the relevant tests are repeatable in situ.   
  See also FAQ no. 38.

41- How is the instrument supported during force measurements?
The forces must be measured, in the various measurement points,      so as not to affect the test results. Rigid extensions must therefore be      used with contact diameter of at least 80 mm, positioned rigidly and against      the movement of the leaf.

42- Is software required for the instrument that measures impact  force?
The standard EN12445 lays down that the forces measuring instrument  must be equipped with a plotter or XY recorder. The standard EN 12453, that  sets the limits, also lays down somewhat detailed criteria of acceptability;  for example peaks after the first one are admissible provided they are of decreasing value. All this requires a check on the graph of the forces. At present, to our knowledge, no instrument is capable of displaying the  graph directly.

43- Where can the forces measuring instrument be purchased?
The information available to UNAC indicates that it is currently    possible to purchase the instrument required by European standards from (in    alphabetical order):
• Drive Test GmbH (www.drivetest.de)
• GET Industrieelektronik GmbH (www.gte.de)
• Microtronics S.r.l. (www.microtronics.it)
• Normagate S.r.l. (www.normagate.com).

  UNAC does not guarantee the quality of the producers and relevant products  indicated.

    44- Is the flashing light required by the European standards?
The standards relating to the safe use of motorised gates and  doors do not indicate it as obligatory, but instead refer its use to evaluation  of the risks in installation. UNAC however recommends that  it be used.

45- Is the emergency stop required by European standards?
  No. The standard EN12553, in paragraph 5.2.2., where it refers to the standard  EN60294-1, even tends to advise against it, declaring it to be "inapplicable".  There may however be areas or situations of use in which it is required. In  this case great care should be taken that the emergency stop does not reduce  the safety of the installation as it disables all the safety devices of the  machine when actuated.

46- Does the Low Voltage Directive have to be applied when installing  an automatic gate, if the whole electrical system (motors, sensitive edges,  photocells, flashing light, etc.) has a very low voltage (24V), and the manufacturer  of the automatic device has supplied a plug to be inserted in the socket for  power supply from the mains?
Yes, for the part relating to the socket, if the voltage of this  socket is, for example, 230V.

47- If considered unlikely, infrequent and not dangerous, is it  possible not to protect against some risks (see for example risks [D] and [F]  indicated in UNAC Guide no. 1 for sliding gates)?
Yes. However users of the automatic door/gate must in any case  be informed in writing in the user manual (or proof book) and, where possible,  the appropriate signs attached.

48- What are the residual risks?
The residual risks are those which, after analysis of the product  (machine), are evaluated as:  unlikely, infrequent and not dangerous, in relation  to operation and the costs required for their elimination or protection.

49- Does the sensitive edge for restricting the operating forces  of the sliding gate have to be installed on the mobile leaf or can it be installed  on the fixed closure jamb?
The purpose of the sensitive edge is to reduce the force of impact  between the mobile leaf and any other object, which could also be a car that  has stopped. Consequently the edge has to be fitted on the mobile leaf. Any  other edges on the fixed parts may be useful for reducing other risks.

50- Can the hold-to-run control also be actuated with TV camera  vision?
No, as the TV camera cannot be considered as being near the door/gate.

51- Is attachment of the product identification plate to the gate  compulsory?
Yes, as the Machinery Directive requires it.

52- If the emergency stop device is actuated, is it possible to  control the door in hold-to-run mode? If a safety device which stops the door/gate  is actuated, is it possible to control the door/gate in hold-to-run mode?
No, in the case of actuation of the emergency stop device. It  should however be checked that installation of an emergency device does not  reduce the safety of the door/gate.
  Yes, in the case of tripping of the safety device, but make sure that all the  hold-to-run conditions are observed as specified in the standard EN 12453 (including  the position of the controls in relation to the view of the door/gate).

53- Is automatic restarting possible after a power cut?
An intentional reset action is not necessary after a stoppage  if efficiency of all the protection devices for ensuring safety has been ascertained.

54- How many photocells should be installed and where for the gate  to comply with standards?
It should be pointed out that the photocells (type D device)  are not always compulsory, depending on the "type of actuation of the door/gate"  according to the provisions of schedule 1 of the standard EN 12453. According  to this schedule, photocells are always used in combination with the type C  device (forces restricting means). All this being so, in order to establish  the quantity of photocells, the existing risks have to be analysed and an evaluation  carried out as to whether a photocell reduces the risk. In the event of a photocell  being installed and where the gate opens onto a public area, even if not specified  by the standards, it is usually preferable to install it on the outer side  (the one in the public area). Finally, in order to evaluate the position, it  has to be considered that, for the working test, the 700x300x200 mm parallelepipeds  are used to obscure the "ray".

55- Do the photocells and the safety edges sold separately from  the drive units require the EC declaration of conformity for safety components  (pursuant to the Machinery Directive Annexe II-C)? With which standards must  they comply?
The sensitive edges used to limit the impact forces of the motorised  door/gate must observe the requirements of the standard EN 12978 and must have  the EC declaration pursuant to the Machinery Directive according to annexe  II-C.
  The photocells used for sensing persons are not safety devices and do not come  within annexe IV of the Machinery Directive. They should be used in addition to  the devices for limiting working forces and must observe the requirements of  the standard EN 12453.

56- Which features must the photocells for automatic doors/gates  have? Are "self-aligning" photocells allowed?
The photocells (including those referred to as "self-aligning"),  which have a presence sensing function in addition to limitation of the working  forces of the leaf, must fulfil the requirements and pass the tests indicated  in the standards EN 12453 for this type of device (type D).

57- Can photocells, not being safety devices, not be "fault safe"?
No minimum category for photocells (type D presence sensing device)  is laid down in relation to fault safety. However a periodical check on the  device is laid down at intervals of less than 6 months.

58- Do photocells with a reflector comply with standards?
Some devices available on the market use polarised reflectors  and are therefore able to pass the test laid down by the standard EN 12445  with the 70x30x20 cm parallelepiped that has a reflecting surface.

59- Can infrared radar be considered a safety device?
The standards do not lay down which technology to use for the  safety devices. They must in any case observe the requirements defined by the  standards on the basis of the function performed by the device (type C, D or  E).

60- Do radio-controlled sensitive edges comply with standards?
If the sensitive edge is used as a type C device, it has to be  checked that the category declared corresponds to the one required.

61- Are periodical checks foreseen on installations of automatic  doors/gates by public authorities?
In all areas subject to Decree Law no. 626/94(Italy) the competent  authorities have the power to carry out checks. In general, in all areas, in  cases of justified requests, the competent authorities have however the power  to intervene.

62- What should the installer do when called to repair an existing  gate brought into service prior to the coming into force of the European standards?
He can carry out the repairs without the obligation of aligning  the system with the new standards.
  It is however advisable to propose to the owner of the motorised gate alignment  of the system with the latest European standards. Should the system not fulfil  the safety and health requirements laid down by the Machinery Directive according  to the state of the art referred to the date of installation of the gate, the  repairs can only be carried out if the system is aligned with the Machinery  Directive and standards currently in force.
  See also FAQ nos. 12, 13 and 14.

63- What should be done for maintenance of old systems in which  300MHz remote controls are still used?
Use of the old 300MHz remote controls has been disallowed for  several years. Even if still working, they must be replaced with products that  comply with the new legal provisions.

64- If there is no maintenance contract, who is responsible for  the automatic door/gate?
The manufacturer of the motorised gate is responsible for conformity of the product to the European directives. Those who perform maintenance are in charge of their work as laid down in the maintenance contract and according to the instructions of the manufacturer. If, contrary to what is laid down by the manufacturer, maintenance is not carried out, the owner and/or the operator of the gate is answerable for any damage caused by malfunctioning (provided that the event cannot be traced to an original or installation defect).


from the makers of the test instrument that we use

According to European laws currently in force, "power-operated automatic gates" are subject to theMachine Directive 89/392/EEC. This means the fitter is required to issue an EC declaration certifying the product's conformity with the safety regulations in force.

In November 2000 the E.U. issued new regulations regarding automatic gates and doors specifically:
EN12453 "Industrial, commercial and garage doors and gate - Safety in use of power operated doors - Requirements" provides a detailed outline of the construction requirements and EN12445"Industrial, commercial and garage doors and gate - Safety in use of power operated doors - Test methods", describes the in-situ test methodologies, and is therefore aimed at fitters.

Of course, 
mechanical safety issues are connected to the hazardous nature of moving parts and therefore the crushing force generated by the motor, which is precisely why the standard EN12445 details, for each gate typology, the tests which must be carried out to make sure the forces in play do not exceed the prescribed limits.

To this end, the said legislation envisages the use of a specific force gauge (which must meet the requirements of art. 5.1.) and an extremely accurate and detailed measuring procedure: Take 
the measurement of an ordinary sliding gate, for example: the certification process requires a test involving the measurement of the force in at least 9 points (three horizontal distances from the point of closure, each one measured at three different heights).

What is more, at each measurement point three tests have to be carried out, from which the arithmetic average is then taken to provide the numerical evaluation parameters.
In light of all this, the gauge obviously needs to be as light as possible, and should be manageable, versatile and - above all - simple to use: discover Microtronics™ products!
