Building hardware - Emergency exit devices operated by a lever handle or push pad, for use on escape routes - Requirements and test methods

This European Standard specifies requirements for the manufacture, performance and testing of emergency exit devices mechanically operated by either a lever handle or a push pad for the purpose of achieving a safe exit under an emergency situation on escape routes.
The suitability of an emergency exit device for use on smoke/fire-resisting door assemblies is determined by fire performance tests conducted in addition to the performance tests required by this European Standard. Annex B indicates additional requirements for these products.
This European Standard covers emergency exit devices, which are either manufactured and placed on the market in their entirety by one producer, or produced by more than one producer and subsequently placed on the market as a kit in a single transaction.

The performance tests incorporated in this European Standard are considered to be reproducible and, as such, will provide a consistent and objective assessment of the performance of these emergency exit devices. Where panic situations are foreseen, reference should be made to EN 1125, covering panic exit devices operated by a horizontal bar. See definition 3.18. Where additional security is required for exit doors, reference should be made to prEN 13633 covering electrically controlled panic exit systems, or to prEN 13637 covering electrically controlled exit systems for use on escape routes. See Bibliography. Due to the wide range of emergency exit devices, the reader is advised to refer to the scope and the detailed contents of this European Standard for coverage but, for information and general guide, this revised European Standard now deals with: • emergency exit devices designed to be used in emergency situations, where people are familiar with the exit and its hardware and therefore a panic situation is most unlikely to develop; • emergency exit devices for use on hinged or pivoted door leaves only; • range of emergency exit devices including those for use on double doorsets (see 7.10); • two specific types of operation: emergency exit devices with “lever handle” operation, type A (see 3.9, see Figures 1 and 3) and emergency exit devices with “push pad” operation, type B (see 3.15, see Figures 2 and 4); • two categories of emergency exit device projection in order to maximize the width of the escape route, and minimize the projection from the door face where either or both of these criteria are of importance (see 4.1.12); • exceptional case of emergency exit devices intended for use on single leaf inwardly opening exit doors. It is assumed throughout this European Standard that emergency exit doors generally open towards the outside in order to assure safe escape. However, there are cases such as hospital or hotel bedroom doors, classroom doors, etc. where local building regulations allow, by way of exception, the exit door to open against the direction of exit; • double doorset emergency exit devices of which the first opening leaf is equipped with a panic exit device conforming to EN 1125 and the second opening leaf is equipped with an emergency exit device conforming to EN 179. It is essential that this combination undergoes an additional test for approval (see 4.2.4). This European Standard does not cover the following:

assessment made by using a measuring tool 4 Requirements 4.1 Design requirements 4.1.1 General Compliance with the design requirements shall be as Table 1.
4.1.2 Release function An emergency exit device shall be designed to release a door at all times from the inside in less than 1 s, by one single hand operation only, not requiring the use of a key or other similar object. It shall be designed to release the door without any delay from the time the operating element is operated to the released position of the mechanism. The operation of the operating element shall enable immediate exit from the inside at all times regardless of any auxiliary locking and/or unlocking means being incorporated, such as a deadbolt or outside access device. Compliance shall be verified by visual inspection, functional tests and/or measurements. 4.1.3 Release operation The release direction of an emergency exit device shall not be opposite to the direction of the door opening. Compliance shall be verified by visual inspection and functional tests.

4.1.8 Exposed edges and corners An emergency exit device shall have all edges and exposed corners, that are likely to cause injury to persons using the exit, rounded to a radius of not less than 0,5 mm. Compliance shall be verified by visual inspection and measurements. 4.1.9 Temperature range Materials selected in the design of an emergency exit device shall be suitable for the operation of the emergency exit device between temperatures of −10 °C and +60 °C. This requirement shall be verified by the test specified in 6.2.2. The maximum operating force at −10 °C and at +60 °C shall not exceed 50 % in excess of the operating forces measured at 20 °C. 4.1.10 Suitability of emergency exit devices for use on smoke/fire-resisting doorsets Emergency exit devices that are suitable for use on smoke/fire-resisting doorsets shall conform to the requirements of 4.2.3, 4.2.4, Annex B and be classified according to 7.4.

Lever handles shall be designed to have a minimum length (dimension X) of 120 mm, measured from the axis of rotation to the free end, and the axis of rotation no more than 150 mm (dimension Z) from the leading edge of the door. See Figure 3. Compliance shall be verified by visual inspection and measurements 4.1.13 Operating element projection No part of an emergency exit device, when the door is in any position, shall project (dimension W) from the face of the door more than:  category 1: projection up to 150 mm (large projection);  category 2: projection up to 100 mm (standard projection). NOTE 1 See Figures 3 and 4 for illustration of dimension W (projection). NOTE 2 Category 1 does not apply to type A operation. Compliance shall be verified by visual inspection and measurements. 4.1.14 Operating element face With the emergency exit device secured, the width of the operating element (dimension V) shall be not less than 18 mm. The shape of the operating element shall facilitate the application of the operating force to the lever handle or the push pad. Verification shall be made in accordance with a) and b). See Figure 5. a) If the operating element is a lever handle, it shall have on its operating face – to which the release force is applied – a minimum thickness of 5 mm, either with a flat surface or with a rounded surface featuring a radius of not less than 5 mm. b) If the operating element is a push pad, it shall have an operating face of not less than 1 400 mm2.
For the convenience of more architectural design freedom and less sophisticated production it is acceptable to allow the lever handle to have a reduced cross-section of not less than 15 mm width (dimension V) and not less than 4 mm thickness on the operating face, provided this reduction is within 20 mm from the free end of the lever handle. Compliance shall be verified by visual inspection and measurements. 4.1.15 Lever handle free end To minimize the risk of injury or of trapping clothes, the free end of a lever handle shall point towards the door such that the dimension “U” is not less than 40 mm, the dimension “W” is not more than 100 mm (standard projection) and the angle . between the free end of the lever handle perpendicular to the surface of the door is not more than 30°. See Figure 3.

To allow for particular designs such as bracket supports, bushings, etc. the first 25 mm of the supporting end of the push pad can have any such gaps reduced to 20 mm. See Figure 4. Compliance shall be verified by visual inspection and measurements. 4.1.18 Test rod To reduce the risk of trapping fingers and/or the blocking of the emergency exit device, any gap shall not trap a test rod (of 10 mm diameter by 100 mm in length) by its 10 mm diameter in any position during the operation of the emergency exit device. Compliance shall be verified by visual inspection and measurements. 4.1.19 Push pad release operation The design of a push pad shall be such that the release operation of the emergency exit device cannot be blocked by the application of a force in the direction of the door opening, anywhere on the exposed operating surface that moves in the direction of opening during normal release operation. Compliance shall be verified by visual inspection and functional tests. 4.1.20 Accessible gap An emergency exit device shall be designed such that the top surface of any operating element, chassis or other mounting assembly does not contain any accessible gap that could inadvertently be blocked by a foreign object, resulting in failure of the emergency exit device to operate. A steel piece of 10 mm × 15 mm × 20 mm placed in any accessible gap and in any orientation shall not prevent correct operation of the emergency exit device. Compliance shall be verified by visual inspection and measurements.

WZR Key R is the minimum gap between the push pad and the surface of the door leaf W is the maximum projection Z is the distance from the leading edge of the door Figure 4 — Critical dimensions of type B emergency exit devices

4.1.21 Door free movement
The design of an emergency exit device shall be such that the bolt head(s), once the door has been released to open, does not restrict or impede the free movement of the door. The design of an emergency exit device can include a dogging mechanism or an automatic relatching device. If the exit device is equipped with a dogging mechanism or a device retaining the bolt(s) retracted, this shall not impede the free movement of the door once released. An exit device shall be designed to avoid accidental release of the bottom bolt, preventing the free opening of the door. Exit devices intended for use on smoke/fire-resisting doors, shall comply with Annex B for additional requirements.
Compliance shall be verified by visual inspection and functional tests carried before and also after durability test. 4.1.22 Top vertical bolt An emergency exit device with top and bottom vertical rods shall include a mechanism to ensure that the releasing and/or the manipulation of the bottom vertical rod bolt head does not release the top vertical rod bolt head. This is verified by pushing the bottom bolt head up to its flush position with the bolt case. Compliance shall be verified by visual inspection and functional tests carried before and also after durability test.
4.1.23 Covers for vertical rods If covers are provided to surface fixed vertical rods to achieve abuse resistance, they shall have secure fixings and only be removable by means of a specific tool. Compliance shall be verified by visual inspection and functional tests, or (if not removable by a specific tool) the emergency exit device shall meet the performance requirements of 4.2.6 with the covers removed. The design of an emergency exit device may provide for a guide(s) to retain the vertical rods.

Compliance shall be verified by visual inspection and functional tests carried before and also after durability test. 4.1.25 Keepers dimensions The design of a floor keeper shall be such that dust and dirt can easily be removed with a conventional vacuum cleaner. If the keeper is not fitted flush it shall not exceed 15 mm in height (dimension H) from the finished floor level and shall be chamfered in the direction of escape at an angle (M) not exceeding 45° from the horizontal, and any up stand (dimension P) shall not exceed 3 mm. See Figure 6. Compliance shall be verified by visual inspection and measurements. HPM Key H is the height of the floor keeper M is the angle from the horizontal P is the up stand of the floor keeper Figure 6 — Floor keeper dimensions 4.1.26 Lubrication Where periodic lubrication is required, it shall be possible to lubricate without dismantling the emergency exit device. No additional lubrication shall be required before 20 000 cycles have been attained, and at no less interval than 20 000 cycles thereafter. This requirement shall be verified in accordance with 6.3.4. 4.1.27 Door mass and dimensions The door mass and door dimensions shall be limited to the following for the purposes of an emergency exit device tested on a test door according to 5.2.2:  maximum door mass: 100 kg or 200 kg
according to the classification;

An outside access device that is not specified by the producer as designed to be compatible with a specific emergency exit device shall not be considered to be in conformity with this document. When an outside access device is intended for use with a thumbturn cylinder, the size and any positioning of the thumbturn shall not interfere with the operation of the emergency exit device from the inside. Where National Building Regulations accept direct connection of the exit device mechanism with the outside lever handle, which when being blocked at any position may render the exit device inoperable from the inside, this shall be clearly stated in the installation instructions, as in 4.3. Where an outside access device is intended for use with a cylinder and a key left inside a cylinder at any position can render the emergency exit device inoperable from the inside then this shall be clearly stated in the installation instructions, as in 4.3 and Annex A. Compliance is verified by a visual and mechanical examination, which shall include all the functions of the outside access device which have been declared by the producer of the emergency exit device. Compliance shall be verified by visual inspection and functional tests. The examination shall confirm that the release forces of the emergency exit device are still within the limits of 6.3.2 with the outside access device installed.
