6 Endurance Test 6.1 The release mechanism and latches shall function as intended for 100,000 consecutive cycles of operation without failure or excessive wear of the parts. 6.1 revised July 12, 2012 6.2 The assembly is to be installed on a simulated door and frame assembly in accordance with the manufacturer’s instructions. A motor-driven mechanism or other appropriate actuating device is to trigger the actuating bar to release the latches and push the door open, as in service. The rate of operation is to be approximately 15 per minute. For this test, the assembly is to be lubricated with the same material that is provided at the factory or recommended by the manufacturer. 7 Emergency Operation Test 7.1 With the door latched, the release mechanism shall be constructed so that a horizontal force of 15 pounds (66 N) or less will actuate the actuating bar and cause the latches to unlatch from the strike. When the latched door is subjected to outward force as described in 7.5 and 7.5, a force of 50 pounds (220 N) or less shall actuate the crossbar or push pad. 7.1 revised July 12, 2012 7.2 The sample is to be subjected to the 15-pound (66-N) test before and after the Endurance Test, Section 6, and subjected to the 50-pound (220-N) test after the Endurance Test, Section 6. A product which incorporates operating parts having a solidus point less than 1 000°F (538°C) shall also be subjected to the 15-pound and 50-pound tests after the Elevated Ambient Exposure Test, Section 8, and after the Low Temperature Impact Test, Section 9. 7.3 The measurement shall be taken at the center and 1 .5 in. (38 mm) from each end on the actuating surface perpendicular to the door in the direction of swing. 7.3 added July 12, 2012 7.4 A horizontal force of 250 pounds (1100 N) is to be applied to the door approximately 3 inches (76.2 mm) from the latch side and 40 inches (1 020 mm) from the floor in the direction of the door swing.
