TEST DETAILS 6.1 Closing Force Test 6.1.1 Prior to the start of the cycle test 6.2, draw a line on the floor parallel to the doo
13、r in the 45 degree + 2 degrees open position. 6.1.2 Conduct the closing force test at the beginning of the cycle test. Test: Open the door to the 45 degree mark on the floor, and position the force gage to contact the door at 30 inches (762 mm) from the pivot axis. 6.1.3 In the case of spring hinges
14、, the manufacturer shall elect to achieve the required closing force with a minimum of two or all three of the hinges being tested and shall clearly indicate the number of hinges required to be tensioned to meet the value specified. 6.2 Cycle Test 6.2.1 Mount hinges or pivots in accordance with 4.1
15、and 4.2 and set closing force of adjustable hinges or pivots in accordance with 5.2. 6.2.2 Mechanically open the door to 90 degrees + 5 degrees and release, allowing the hinges or pivots to completely close the door within 5 degrees of the normal closed position. One opening and closing constitutes
16、one cycle. Repeat for the required number of cycles as given in 5.3.1. Cycles per minute shall be a maximum of 20. 6.2.3 Double acting hinges or pivots shall be cycled in each direction. Alternately cycling the test door in one direction and then the other for the required number of cycles shall be
17、permitted. Cycling the door for 25,000 times in one direction and then 25,000 times in the other for the required number of cycles given in 5.3.1 shall be permitted. One opening and closing in each direction constitutes two cycles. 10 6.2.4 At the conclusion of the cycle test (6.2), remeasure and re
18、cord vertical and lateral relationship of all hinges or pivots in 5.1. All measurements shall be taken at the same door position as initial measurements made at the start of the test. 6.3 Latch Test for Single Acting Doors 6.3.1 After the re-measurement in 6.2.4, release the door from 45 degrees ope
19、n and measure the impact of the door at the 5 degree open position. The impact shall not be less than a 4.5 lbf (20 N) at a point where a latch is located. (See 4.3.2) 6.4 Static Load Test 6.4.1 Lateral change and deformation. At the conclusion of the latch test 6.3 and with the door in the 0 degree
20、 (closed) position, add and remove 150 lbs. (68 kg) at a point on the door at a horizontal distance from the pivot axis equal to the test door width shown in 5.2.1. Lateral shift of the door leaf away from the jamb at top hinge shall not exceed .062 in (1.6 mm). Exception: Double acting spring hinge
21、s and pivots are not subject to this test. 6.5 Salt Spray Test. This test shall be conducted in accordance with 3.1 and 3.2 in ANSI/BHMA A156.18-2012 for Materials and Finishes for the exposure times given below. Requirements. Salt Spray Exposure Hours All Grades Painted material 48 Hours Non-Ferrou

The parts for finish testing shall be selected at random and shall
23、 be three pieces. When one part is noticeably poorer than the others tested, this defective part shall be ignored as an isolated defective part. 11 7. HINGE DESCRIPTIONS AND IDENTIFYING NUMBERS.
