17、 tow shall be built-up of several groups of multifilament 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
18、 finished sleeve meet the mechanical and environmental requirements. One length of sleeve shall be built-up of one type of tow. 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 so that the sleeve meet the re
19、quirements 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 maximum difference measured on a
20、 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. 1) All parts quoted in this document. prEN 6049-003:2016 (E) 4 Braiding pattern Key 1 Pitch 2 One tow d = Inner diameter Figure 1 Composition of the

24、 tows. 4.3.2 Temperature range The operation temperature of the protection sleeves shall be: a) Maximum: 240 C; b) Minimum: 55 C. NOTE Above 175 C: loss of water repellent properties. 4.3.3 Resistance to fluids range After testing according to EN 6059-303, the retention of the tensile strength shall
25、 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 test according to EN 605
26、9-302 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 less than 0,03 N. Degrada
27、tion 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 shown in Table 2. For th
