It shall be used together with EN 3745-100. 2 Normative references The following documents are referred to in the text in such a way that some or all of their conte
24、nt constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 3745-100, Aerospace series Fibres and cables, optical, aircraft use Test methods Part 100:

26、ms and definitions are listed in this document. ISO and IEC maintain terminological databases for use in standardization at the following addresses: IEC Electropedia: available at http:/www.electropedia.org/ ISO Online browsing platform: available at http:/www.iso.org/obp 4 Preparation of specimens
27、Prepare test sample in accordance with EN 60794, Method E1. Fibres coated by UV-curable acrylic resin can be cleaned (e.g. from cable filling compounds), without causing damage to the coating using any cleaning agent recommended by the manufacturer of the fibres. However the use of chlorine-based cl
28、eaning agents should be absolutely avoided, since they can attack the coating even after their use and in vapour phase. If not at standard test conditions, the specimens shall be subjected to standard test conditions and stabilized at these conditions for 24 h as defined in EN 3745-100. Attenuation
29、should be measured, in accordance with EN 3745-301 method C, before the test. Sample length can be more than 100 m for test A and 5 m for test B. BS EN 3745-505:2018EN 3745-505:2018 (E) 5 5 Apparatus The apparatus shall comprise: Fibre and cable attenuation test apparatus as defined in EN 3745-301;
30、Tensile test apparatus in accordance with EN 60794, Method E1 (for test A); Tensile test apparatus capable of measuring the specified elongation to an accuracy of 1 % (for test B). 6 Method 6.1 General For measuring cable tensile strength method A or B can be used. Unless otherwise stated, the test
31、conditions shall be standard atmospheric conditions. 6.2 Method A (using transfer device and chuck drum) The test shall be carried out in accordance with EN 60794, Method E1. 6.3 Method B (using clamping device) The cable shall be pulled between two mandrels. The initial length of the test specimen
32、between the mandrels (min 50 mm diameter) shall be (250 1) mm. The pulling speed shall be (50 10) mm/min. The cable shall be wrapped at least three (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
33、 during test. 6.4 Final measurements and requirements If specified the value for the following shall conform to those given in the product standard (see Table 1): Table 1 Object Test method Aspect Visual examination as defined in EN 3745-201 A and B Attenuation Maximum recorded fibre strain at maxim
34、um tensile rating Maximum attenuation change at maximum tensile rating Maximum attenuation change before and after test (without load) A A and B A and B Mechanical characteristics Maximum load up to optical discontinuity Breaking load for the complete cable A and B A and B BS EN 3745-505:2018This pa
