31、tleless loom webbing is used, the weft shall be locked by an additional locking thread or by any other system, which 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
32、 of stitching shall contrast with the tape in colour or surface appearance. 4.1.4 Components Any component that can 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
33、no load transmitting part to the body shall break completely. In addition the dummy shall not be released from the 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 abseili
34、ng 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 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
35、be sup- plied. NOTE Second and subsequent 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). This shall be checked, after each of the ad- justments, in acc
36、ordance 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 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 accor
37、dance with EN ISO 139. Tests may then be done outside the conditioning room, but the temperature shall be (23 5) C and the tests shall begin within 5 min of removal from the conditioning room.

38、5.2 Procedure 5.2.1 General Verify the requirements 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
39、 per dimension. 5.2.2 Stability of tapes 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 ar
40、e met. 5.2.4 Type A harnesses 5.2.4.1 Put 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
41、 dummy. Under this load, the rope attachment 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 gradual
42、ly to (15 3 ,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 (15 3 ,0 0 + ) kN as before and hold the force for (3 0,25) min be- fore release. After rel
43、ease mark the tape at the 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. 5.2.4.4 In the head down position of the dummy (see Figure 3), mark the tape at the outer edge of any load bearing buc
44、kle 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. Reapply the force immediately and increase gradually to (10 3 ,0 0 + ) kN as before and
45、 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 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
46、test dummy according to Figure 3 and attach it with a single 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 pla
47、ced approximately symmetrically about the plane of symmetry 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 ,0 0 + ) kN over a period of (2 0,25) min. Hold this
48、force for (1 0,25) min and then release the tension completely over a maximum of 1 min. Reapply the Licensed Copy: :FULLNAME, : DATE, Uncontrolled Copy, (c) BSI EN 12277:2007 (E) 9 force immediately and increase gradually to (10 3 ,0 0 + ) kN as before and hold the force for (3 0,25) min be- fore re
49、lease. 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 measure the distance between the two marks. 5.2.5.4 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 2 ,0 0 + ) kN over a period of (2 0,25) min. Hold this force for (1 0,25) min and then rele
