32、rce measurement requirements Force measuring apparatus for static testing of components and systems shall conform to EN10002-2. The calibration of measuring apparatus should be traceable to an approved physical properties laboratory or approved calibration service in accordance with the accuracy req

33、uired for the test (consult EN 45001). 4.1.2 Requirements for rate of stressing 4.1.2.1 Metallic materials The rate of stressing shall conform to EN 10002-1. 4.1.2.2 Textile materials The crosshead velocity for components in the length range 1,0 m to 2,0 m shall be within the range of50mm to 150 mm

34、per minute. Components shorter than 1,0 m shall be tested with a proportionately lower crosshead velocity. Components longer than 2,0 m may be tested with a proportionately higher crosshead velocity. 4.2 Torso dummy The torso dummy for static and dynamic testing of relevant components and systems sh

35、all conform to the dimensions and requirements described at Figure 1. The mass of 100 kg should have a tolerance of 1 kg. The centre of gravity should be(200 25) mm above the perineum.

The rigid anchorage point shall be a ring of(201)mm bore and (15 1) mm diameter cross section, or a rod of same diameter cross section. The height of the ri

39、gid anchorage point shall be such as to ensure that no part of the component or system under test, or of the torso dummy or rigid steel mass, shall strike the floor during the test. 4.4.2 Force measurement apparatus The force measuring apparatus shall be capable of measuring forces from 1,2 kN to 20
