This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2001, and conflicting national standards shall be withdrawn at the latest by May 2001. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This standard is part of a series of European Standards for industrial, commercial and garage doors and gates that are identified in prEN 13241:1998. No existing European Standard is superseded. This standard covers the requirements for power operated doors, based on hazardous situations which can be encountered when a door is used normally and also hazardous situations likely to occur because of foreseeable misuse. The requirements specified in this standard are in the form of safety objectives. Where a technical means or solution is described, this should not be considered to be the only method of meeting the requirement, but simply an example. Annex A is normative. Annex B is informative. 1 Scope 1.1 General This standard specifies the performance requirements in regard of the safety in use for any type of power operated doors, gates and barriers intended for installation in areas in the reach of persons, and for which the main intended uses are giving safe access for goods and vehicles accompanied or driven by persons in industrial, commercial or residential premises. 1.2 Exclusions It does not apply to ? lock gates and dock gates; ? doors on lifts; ? doors on vehicles; ? armoured doors; ? doors mainly for the retention of animals; ? theatre textile curtains; ? horizontally moving doors 50 mm when the opening gap is ? 500 mm and not 100 mm when the opening gap is 500 mm. Alternatively the door leaf shall be fitted with a deformable closing edge where the available deformation shall be more than the stopping distance which shall result in a static force of no greater than 150 N on a 80 mm diameter test piece; ? the leaf movement shall not be initiated by manual controls other than hold to run controls; ? the person controlling the door shall be in full view of the door and in the vicinity of the door during the leaf movement and shall not be in a hazardous position himself; NOTE Remote control devices can be used as hold to run controls only if designed to meet the requirements specified in the 3 rd indent above. ? the manual actuators shall meet the requirements of 5.2.8; ? the speed of the main edge shall be ? 0,5 m/s. In case of two main edges, e.g. bi-folding doors, the speed of closing the gap shall not exceed 0,5 m/s; ? operation of the door by unauthorised persons, as specified in 5.5, shall be prevented either by technical means or specific organisation. If these requirements are fulfilled then other safety devices for safeguarding of crushing, shearing and drawing-in points are not needed. 5.1.1.5 Limitation of forces Forces shall be considered to be safe if the values specified in Annex A are not exceeded, when measured according to EN 12445 with an instrument incorporating a spring through a plate of 80 mm diameter. The spring shall have a spring ratio of 500 N/mm and the rising/falling time of the amplifier shall not be ? 5 ms. 5.1.1.5.1 Force limiting devices When limitation of forces is achieved through protective equipment, such equipment shall be designed to meet the requirements specified in 5.1.1.6 and in prEN 12978 : 2000. Page 11 EN 12453:2000 5.1.1.5.2 Safeguarding crushing points by force limitation Crushing points may be safeguarded by limitation of the forces. The reversing function, if provided, can be excluded as soon as the closing gap is ? 50 mm for a vertically moving door and ? 25 mm for a horizontally moving door. 5.1.1.5.3 Safeguarding shearing points by force limitation Shearing hazards occurring between secondary closing edges can be safeguarded by limitation of forces measured at the secondary closing edges to less than 150 N static and less than 400 N dynamic in addition to ? either a distance of at least 25 mm between passing edges ? or the passing edges shall be provided with round edges with radius of at least 2 mm for each edge and a combined radius (sum of the 2 radii) of at least 6 mm (e.g. at least 2 mm + 4 mm or 3 mm + 3 mm). 5.1.1.5.4 Safeguarding drawing-in points by force limitation Drawing-in points cannot normally be safeguarded by limitation of forces only. Therefore, the values specified in Annex A cannot be considered as relevant to the safeguarding of drawing-in points. 5.1.1.6 Sensitive protective equipment In normal operation, pressure sensitive protective equipment (PSPE), electro-sensitive protective equipment (ESPE) and inherent (built into the drive) protective equipment shall be designed so that a)when they are in working order, they respond by giving an appropriate output signal(s) ? when part of a person is in the detection zone of the ESPE, ?or when a person applies the activating force at any point within the active area of the PSPE sensing element, ? or when closing on a test piece positioned at any angle between 90° and 45° to the direction of the motion if the signal from the sensing unit is within a specified signal range for inherent systems (see figure 1). 1 2 Key 1 Direction of motion 2 Test piece Figure 1 Positioning of test piece b)the control command for stopping the hazardous leaf movement (off state of the output signal switching device) is maintained for so long as the protective device is actuated, or until a signal for reversing the direction of movement of the door leaf is given; c)a device will prevent forces delivered at any point of main and/or secondary edges from being beyond those specified in Annex A, or will ensure that, in no circumstances, a person can be touched by the moving door leaf. For PSPE, the forces can be exceeded for the extreme 30 mm of each end, but the device shall remain active; Page 12 EN 12453:2000 d)the danger points are safeguarded up to a height of 2,50 m above the floor in a way that unprotected zones of the danger points do not remain; e)if a single fault occurs in the components between the sensing unit and the door control (i.e. interconnecting elements, control, monitoring function, OSSD), which prevents the control signal from stopping the leaf movement: ? either they maintain their protective function if according to category 3 or 4 of EN 954-1; ? or they are monitored according to category 2 of EN 954-1, with the acceptable deviation that the check of the safety function can be done at the latest at one of the final end positions of the leaf, i.e. the check need not take place before the hazardous leaf movement. If a fault is detected, an appropriate signal shall initiate a command to prevent any further endangering leaf movement, or the control shall switch over automatically to a hold-to-run control (see 5.1.1.4). f)if a single fault occurs in the sensing unit preventing the control signal from stopping the leaf movement: ? either it maintains its protective function according to category 3 or 4 of EN 954-1 ? or it is monitored according to category 2 of EN 954-1, with the acceptable deviation that the check of a signal from the sensing unit can be done at the latest at one of the final end positions of the leaf, i.e. the check need not take place before the hazardous leaf movement. If a fault is detected, an appropriate signal shall initiate a command to prevent any further endangering leaf movement, or the control shall switch over automatically to a hold-to-run control (see 5.1.1.4). If not all possible occurrence of non-active areas can be detected, periodic checks, at intervals not greater than six months, covering the whole active area shall be specified in the maintenance instructions for the door. NOTE The periodic checks specified in the instructions may be carried out by the user or any other organisation. g)they meet the requirements of prEN 12978:2000. 5.1.2 Safeguarding against hazards caused when doors can lift persons Hazardous situations listed in 4.1.2 for vertically moving doors, shall be avoided by either: ? limiting the force available at the door leaf or ? preventing anyone from travelling with or being lifted by the door
