   1. Design requirements

      1. General

Compliance with the design requirements shall be as Table 1.

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.

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.

Lever handle operated emergency exit devices shall be designed to release the door following a movement of the lever handle in a downward rotational direction.

Compliance shall be verified by visual inspection and functional tests

Push pad operated emergency exit devices shall be designed to release the door following a movement in the direction of the door opening in an arc downwards or to the side. This requirement shall also apply to emergency exit devices intended for use on inwardly opening single leaf exit doors.

NOTE The term “pull pad” is sometimes used instead of “push pad” for use on inwardly opening single leaf exit doors.

Compliance shall be verified by visual inspection and functional tests

The design of an emergency exit device intended for use on double doorset leaves shall allow both leaves to be opened simultaneously and to swing freely in the direction of exit once the door has been released.

NOTE 1 The construction and installation of a specific doorset assembly, including choice of hinges, leaf thickness and leaf width, can have a significant effect on the ability of both leaves to open simultaneously. These issues are beyond the scope of this European Standard. Additional guidance is given in A.5.

NOTE 2 For example, on rebated double doors, operating the emergency exit device on the inactive leaf will release both the inactive and the active leaf.

Compliance shall be verified by visual inspection and functional tests carried before and also after durability test.

The corrosion resistance shall comply with 4.2.9 or be at least grade 3 in accordance with EN 1670:2007, 5.6.

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.

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 °С and +60 °С. This requirement shall be verified by the test specified in 6.2.2. The maximum operating force at -10 °С and at +60 °С shall not exceed 50 % in excess of the operating forces measured at 20 °С.

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 В and be classified according to 7.4.

Push pads shall be designed such that the operating element can be installed at 250 mm or less (dimension Z) from the leading edge of the door when the door is in the closed position. See Figure 4.

Compliance shall be verified by visual inspection and measurements

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

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.

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.

1. 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.

2. 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.

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 a between the free end of the lever handle perpendicular to the surface of the door is not more than 30°. See Figure 3.

Compliance shall be verified by visual inspection.

To allow sufficient room for hand operation, lever handles shall be designed such that a rounded (17,5 mm radius) test block of 35 mm width and 95 mm length held at an angle of not more than 15° to the surface of the door can be passed freely between the lever handle and the surface of the door. This requirement shall be fulfilled at any position of the lever handle. See Figure 3.

Compliance shall be verified by visual inspection and measurements.

The gap between a push pad and the door face shall not be less than 25 mm (dimension R) at any position of the travel to reduce the risk of trapped fingers and preventing the release of the door.

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.

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.

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.

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 x 15 mm x 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.

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 В for additional requirements.

Compliance shall be verified by visual inspection and functional tests carried before and also after durability test.

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.

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.

The design of an emergency exit device shall include a keeper(s) for protecting the door frame and engaging the bolt head(s) when the emergency exit device is in the secured position.

Keepers shall provide protection for any part of the door or frame that could be damaged by the emergency exit device during the opening and closing cycle of the door.

Compliance shall be verified by visual inspection and functional tests carried before and also after durability test.

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.

H is the height of the floor keeper M is the angle from the horizontal P is the up stand of the floor keeper

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.

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;maximum door height, excluding any rebates: up to 20 % increase of the height of the test door (i.e. maximum increased height = 2 520 mm);

• maximum door width, excluding any rebates: up to 20 % increase of the width of the test door (i.e. maximum increased width = 1 320 mm).

Beyond these limits an emergency exit device shall be additionally tested according to the following:

1. door mass over 200 kg: repeat the durability test in accordance with 6.3.4 and the final examination in accordance with 6.3.8, with the intended door mass;

2. door width over 1 320 mm: no further tests required;

3. door height over 2 520 mm: repeat the release test in accordance with 6.3.2, the abuse resistance test of vertical rods in accordance with 6.3.6 and the final examination in accordance with 6.3.8. Either perform the test with the intended door height or perform the test on test doors 2 100 mm high but with weights added to the vertical rods to ensure that the vertical rods have the same mass that they would have on the door for which the device is specified. In this case, the longest unsupported length of surface fixed vertical rod, at the midpoint of which the abuse force is applied, shall be not less than the one of the door for which the device is intended.

The forces shall be applied in accordance with 5.2.1.

An emergency exit device may be used on a door with shorter dimensions and lower mass than the dimensions and the mass of the door to which it has been tested.

The provision for a connection of an outside access device (key, cylinder, lever handle, knob, etc.) shall not, in any, way render the emergency exit device inoperable from the inside, whether the outside access device is tested in the fully locked or unlocked position with the key removed. The installation instructions shall clearly indicate the approved configurations for outside access. See Annex A.

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.

Materials in products shall not contain or release any dangerous substances in excess of the maximum levels specified in existing European material standards or any national regulations.

Compliance shall be verified by visual inspection of documents supplied by the producer.
