30、ifilament fibres made from Meta-aramid. The number of groups which forms a tow and the width of the tow depends on the braiding configuration (braiding Figure 1 and braiding angle) of the sleeve, see 4.1.2. The thickness of the tow shall be so that the finished sleeve meet the mechanical and environ
31、mental requirements. One length of sleeve shall be built-up of one type of tow. 1) All parts quoted in this document. BS EN 6049003:2018EN 6049-003:2018 (E) 5 4.1.2 Composition, dimensions and mass of the sleeve The composition of the sleeve (braiding Figure 1, braiding angle and tow width) shall be
32、 so that the sleeve meet the requirements for dimensions, coverage, expansion range and mass. The coverage shall be 80 % minimum. The braiding Figure 1 shall consist of two groups of tows in two directions. The braiding angle between the two groups shall be equal over the length of the sleeve. The m
33、aximum difference measured on a mandrel with the delivered diameter in accordance with EN 6059-202 is 3 %. Figure 2 and Table 2 give the composition and the dimensions of the sleeve.

38、 tensile strength shall be 90 % minimum with respect to the determined values of non-tested tows. 4.3.4 Water absorption To fulfil the requirements for water absorption, the sleeve shall repel water as tested in EN 6059-305 for 6 hours. This test shall be executed after a high temperature exposure t
39、est according to EN 6059-302 at 175 C. 4.3.5 Mould growth After testing according to EN 6059-306, there shall no external deterioration which would affect service use and no mould growth visible to the naked eye. 4.3.6 Tensile strength of tows The tensile force to be applied per dTEX shall not be le
40、ss than 0,03 N. Degradation of the tensile strength after environmental tests shall be within the limits as mentioned in the relevant paragraph. For this test, unbraided tows of the batch which have been used for braiding of the sleeves may be used. 5 Test methods The tests shall be carried out as s
