35、h 5.2.4.3, 5.2.5.3 or 5.2.6.3 as appropriate. 4.2.3 If there are multiple rope attachment points (for different sizes) the tests in accordance with 5.2.4, 5.2.5, 5.2.6 or 5.2.7 shall be repeated as appropriate for each size as specified in the information to be sup-plied. NOTE Second and subsequent

36、samples can be necessary. 4.2.4 If a harness of type B is adjustable, the range of adjustments shall be within the maximum and mini-mum ranges claimed on the label (in accordance with Clause 6).

39、equirements according to 4.1.1 and 4.1.4 by physical and tactile examination and by measuring with the harness on the dummy loaded in accordance with 5.2.4.2, 5.2.5.2, 5.2.6.2 or 5.2.7.2. For the width in 4.1.1 the measurements shall be made in three locations per dimension. 5.2.2 Stability of tapes

40、 Check the requirements according to 4.1.2 using a test sample of 100 mm minimum length and cut one warp and one weft thread on each type of load bearing tape in the harness. 5.2.3 Threads Check by visual examination that the requirements specified in 4.1.3 are met. 5.2.4 Type A harnesses 5.2.4.1 Pu

41、t the harness on a rigid test dummy according to Figure 2 and attach it with a single rope, according to EN 892, to the test machine in accordance with the instructions for use. 5.2.4.2 Load the harness gradually up to (800 10) N in the head up position of the dummy. Under this load, the rope attach

42、ment points should be placed approximately symmetrically about the plane of symmetry of the dummy. 5.2.4.3 In the head up 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 (15 3,00+) kN over a period of (2

43、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 (15 3,00+) kN as before and hold the force for (3 0,25) min be-fore release. After release mark the tape at the outer edge of any load

44、bearing buckle or adjusting device. Undo the load bearing buckle or adjusting device and measure the distance between the two marks. 5.2.4.4 In the head down position of the dummy (see Figure 3), mark the tape at the outer edge of any load bearing buckle or adjusting device and apply a force increas

45、ing gradually to (10 2,00+) 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 (10 3,00+) kN as before and hold the force for (3 0,25) min before release. After re

46、lease mark the tape at the outer edge of any load bearing buckle or ad-justing device. Undo the load bearing buckle or adjusting device and measure the distance between the two marks. 5.2.5 Type B harnesses 5.2.5.1 Put the harness on a rigid test dummy according to Figure 3 and attach it with a sing

47、le rope, according to EN 892, to the test machine in accordance with the instructions for use. 5.2.5.2 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 of symmetr

48、y of the dummy. 5.2.5.3 In the head up 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 (10 2,00+) kN over a period of (2 0,25) min. Hold this force for (1 0,25) min and then release the tension completely
