37、st conditions Dry the test samples for at least 24 h in an atmosphere of (50 5) C and less than 20 % relative humidity. Then condition these test samples in an atmosphere of (23 2) C and (50 2) % relative humidity for at least 72 h. Then start testing these samples at a temperature of (23 5) C withi

38、n 10 min. 5.2 Procedure 5.2.1 General Verify the requirements according to 4.1.1, 4.1.3 and 4.1.4 by visual and tactile examination. Verify the requirements according to 4.1.2 by measuring with the harness on the dummy loaded in accordance with 5.2.3.2, 5.2.4.2, 5.2.5.2 or 5.2.6.2. For the width in

39、4.1.2 the measurements shall be made in three locations per dimension. 5.2.2 Threads Check by visual examination that the requirements specified in 4.1.3 are met. BS EN 12277:2015EN 12277:2015 (E) 8 5.2.3 Type A harnesses 5.2.3.1 Put the harness on a rigid test dummy according to Figure 4 and attach

40、 it with a single rope, according to EN 892, to the test machine in accordance with the instructions for use. 5.2.3.2 In the head up position of the dummy load the harness gradually up to (800 10) N in the head up position of the dummy. Under this load, the rope attachment points should be placed ap

41、proximately symmetrically about the plane of symmetry of the dummy, then mark the tape at the outer edge of any load bearing buckle or adjusting device and apply a force increasing gradually to (15 3,00+) kN over a period of (2 0,25) min. Hold this force for (1 0,25) min and then release the tension

42、 completely over (1 0,10) min. Reapply the force immediately and increase gradually to (15 3,00+) kN over a period of (2 0,25) min and hold the force for (3 0,25) min before release. After release mark the tape at the outer edge of any load bearing buckle or adjusting device. Undo the load bearing b

43、uckle or adjusting device and measure the distance between the two marks. 5.2.3.3 In the head down position of the dummy (see Figure 4), use the same harness as in 5.2.3.2 then mark the tape at the outer edge of any load bearing buckle or adjusting device and apply a force increasing gradually to (1

44、0 0,30+) kN over a period of (2 0,25) min. Hold this force for (1 0,25) min and then release the tension completely over (1 0,10) min. Reapply the force immediately and increase gradually to (10 3,00+) kN as before and hold the force for (3 0,25) min before release. After release mark the tape at th

45、e outer edge of any load bearing buckle or adjusting device. Undo the load bearing buckle or adjusting device and measure the distance between the two marks. 5.2.4 Type B harnesses 5.2.4.1 Put the harness on a rigid test dummy according to Figure 5 and attach it with a single rope, according to EN 8

46、92, to the test machine in accordance with the instructions for use. 5.2.4.2 In the head up position of the dummy load the harness gradually up to (500 10) N in the head up position of the dummy. Under this load, the rope attachment points should be placed approximately symmetrically about the plane

47、 of symmetry of the dummy, then mark the tape at the outer edge of any load bearing buckle or adjusting device and apply a force increasing gradually to (10 0,30+) kN over a period of (2 0,25) min. Hold this force for (1 0,25) min and then release the tension completely over (1 0,10) min. Reapply th

48、e force immediately and increase gradually to (10 3,00+) kN over a period of (2 0,25) min as before and hold the force for (3 0,25) min before release. After release, mark the tape at the outer edge of any load bearing buckle or adjusting device. Undo the load bearing buckle or adjusting device and

49、measure the distance between the two marks. 5.2.4.3 In the head down position of the dummy, mark the tape at the outer edge of any load bearing buckle or adjusting device and apply a force increasing gradually to (7 0,20+) kN over a period of (2 0,25) min. Hold this force for (1 0,25) min and then release the tension completely over a maximum of 1 min. Reapply the force immediately and increase gradually to (7 2,00+) kN as before and hold the force for (3 0,25) min before release. After release, mark the tape at the
