31、 5.2.5.2, 5.2.6.2 or 5.2.7.2 as appropriate: i) harnesses of type B and D: 28 mm minimum; ii) all other types of harnesses: 43 mm minimum; Licensed Copy: London South Bank University, London South Bank University, Mon May 07 12:28:30 GMT+00:00 2007, Uncontrolled Copy, (c) BSI EN 12277:2007 (E) 7 b)
32、shoulder straps: i) harnesses of type B: 23 mm minimum; ii) all other types of harnesses: 28 mm minimum; c) all other parts: no requirements specified. 4.1.2 Stability of tapes When shuttleless loom webbing is used, the weft shall be locked by an additional locking thread or by any other system, whi
33、ch guarantees that the edges cannot become unravelled when one of the yarns breaks. 4.1.3 Threads Where stitching is used to provide safety and strength (e.g. in joints) the visible area of stitching shall contrast with the tape in colour or surface appearance. 4.1.4 Components Any component that ca
34、n come into contact with the user or any textile part shall be free from burrs and sharp edges. 4.2 Strength 4.2.1 When tested in accordance with 5.2.4, 5.2.5, 5.2.6.3, 5.2.6.4 or 5.2.7 no load transmitting part to the body shall break completely. In addition the dummy shall not be released from the
35、 harness and no load bear- ing buckles or adjusting devices shall slip more than 20 mm. 4.2.2 Any loop or combination of loops which are specified in the instructions for use for abseiling shall pass the tests in accordance with 5.2.4.3, 5.2.5.3 or 5.2.6.3 as appropriate. 4.2.3 If there are multiple
36、 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 samples can be necessary. 4.2.4 If a harness of type B is adjustable, th
37、e range of adjustments shall be within the maximum and mini- mum ranges claimed on the label (in accordance with Clause 6). This shall be checked, after each of the ad- justments, in accordance with 5.2.1. 4.2.5 If the type A or type B harness can be divided into a type C and a type D harness, each
38、component which has a rope attachment point shall meet the requirements of this European Standard. 5 Test methods 5.1 Conditioning and test conditions Condition the test samples in accordance with EN ISO 139. Tests may then be done outside the conditioning room, but the temperature shall be (23 5) C
39、 and the tests shall begin within 5 min of removal from the conditioning room.

40、o 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 Check the requirements
41、 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 Put the harness on a rigi
42、d 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 attachment points should be p
43、laced 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 ,0 0 + ) kN over a period of (2 0,25) min. Hold thi
44、s 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 ,0 0 + ) 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 bearing buckle
45、 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 increasing gradually
46、to (10 2 ,0 0 + ) 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 ,0 0 + ) kN as before and hold the force for (3 0,25) min before release. After release
47、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 single ro
48、pe, 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 symmetry of
49、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 ,0 0 + ) 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.
