Re-engagement force
When an emergency exit device is tested in accordance with 6.3.3, the force required to release an automatic relatching device in order to re-engage the emergency exit device in the secured position shall not exceed 50 N.
The test in 6.3.3 may be omitted if the emergency exit device does not include an automatic relatching device.
Durability
When an emergency exit device is tested in accordance with 6.3.4, the cycling test shall consist of:
100 000 cycles to achieve grade 6;
200 000 cycles to achieve grade 7.
When an emergency exit device equipped with a deadbolt only thrown by a key for additional security is tested in accordance with 6.3.4.2, the cycling test of the deadbolt shall consist of:
25 000 cycles to achieve grade 6;
50 000 cycles to achieve grade 7.
An emergency exit device may be designed to incorporate an additional deadbolt thrown by a key, used only at certain period of time for additional security. The release function shall be tested with any deadbolt thrown. The durability of the deadbolt does not need to be tested to same number of cycles as either the regular latch bolt or an automatic relatching device, or an automatic deadbolt.
Emergency exit devices intended for use only on the inactive leaf of a double doorset shall be tested in accordance with 6.3.4.1 (Test 2); the cycling test shall consist of:
10 000 cycles to achieve grade 6;
20 000 cycles to achieve grade 7.
For rebated double doorsets, it shall not be necessary for emergency exit devices used only on inactive leaves to complete the same number of durability cycles as that required for the active leaf. However, when an emergency exit device is designed for use on either leaf of a double doorset, or for use on a single door, it shall be tested to the complete number of cycles.
After the test, the emergency exit device shall continue to be operable and meet the requirements of 4.1.21, 4.2.2 and 4.2.3.
Where double doorset emergency exits, when 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 this European Standard, the combination shall be tested according to 6.3.4.
NOTE This combination is not permitted in all national regulations.
4.2.5 Abuse resistance - Operating element
Emergency exit device operated by a lever handle
When an emergency exit device is tested in accordance with 6.3.5.1, it shall withstand a perpendicular pull force of 1 000 N and a parallel force of 500 N. See Figure 8.
Emergency exit devices operated by a push pad

Figure 9 — Abuse resistance test force
fter the test, the emergency exit device shall continue to be operable. This requirement shall be checked during the final examination by the tests given in 6.3.8.Security requirement
When an emergency exit device is tested in accordance with 6.3.7, the device shall remain in the locked position and shall keep the door closed when subjected to a force of:
1 000 N for attaining grade 2;
2 000 N for attaining grade 3;
3 000 N for attaining grade 4;
5 000 N for attaining grade 5.
Emergency exit devices conforming to this European Standard have a safety rather than a security function. It is therefore considered essential that the emergency exit device shall continue to be operable after the application of any abuse test forces. The test values in 4.2.7 reflect this requirement and indicate a level of strength that shall be achieved without impairing the escape function of the emergency exit device.
Final examination
At the end of the test programme, the emergency exit device shall continue to be operable and meet the requirements of 4.2.2 and 4.1.21.

General
Any emergency exit device within any one product range having significantly different working components, or working components of significantly different materials, shall be separately tested.
Emergency exit devices intended for use with a mortise lock shall be tested together with the operating element specified by the producer.
Three test samples shall be used for testing in accordance with this European Standard:
test sample A for environmental tests;
test sample В for design and performance tests;
test sample C for reference or further tests.
Alternatively, test sample C can be used also for environmental tests if it is necessary to split temperature and corrosion tests.
Failure of any one test within a sequence constitutes failure of that particular test sample.
In the case of any one test sample failure, the relevant test sequence may be repeated using sample C.
The emergency exit device shall be fitted to the test door in accordance with the producer’s instructions, as in 4.3.
If an emergency exit device is to be used on single leaf doors only, this emergency exit device shall be tested on the test door described in 5.2.2.1, or on the test door described in 5.2.2.2 by using only one of the two leaves, with the unused leaf being clamped secured.
If an emergency exit device is to be used on double doorsets, this emergency exit device shall be tested only on the test door described in 5.2.2.2.
NOTE It is recognized that such emergency exit devices can also, in some circumstances, be used on single leaf doors.
