Sample length can be more than 100 m for test A and 5 m for test B. 4 Apparatus The app
19、aratus shall comprise: Fibre and cable attenuation test apparatus as defined in EN 3745-301; Tensile test apparatus in accordance with EN 187000, Method 501( for test A); Tensile test apparatus capable of measuring the specified elongation to an accuracy of 1 % (for test B). 1) In preparation at the
20、 date of publication of this standard. EN 3745-505:20075 5 Method 5.1 General For measuring cable tensile strength method A or B can be used. Unless otherwise stated, the test conditions shall be standard atmospheric conditions. 5.2 Method A (using transfer device and chuck drum) The test shall be c
21、arried out in accordance with EN 187000, Method 501. 5.3 Method B (using clamping device) The cable shall be pulled between two mandrels. The initial length of the test specimen between the mandrels (min 50 mm diameter) shall be (250 1) mm. The pulling speed shall be (50 10) mm/mn. The cable shall b
22、e wrapped at least 3 turns on each mandrel. NOTE There must be sufficient grip between the test specimen and mandrel to avoid relative movement between cable and mandrel during test. 5.4 Final measurements and requirements If specified the value for the following shall conform to those given in the
