20、 of the tows Each 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 sha
21、ll be so that the 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 s
22、leeve 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 maximum differe
23、nce 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. 1) All parts quoted in this document. 2) Published as ASD Prestandard at the date of publication of this standard.

26、y, code 9. 4.2.2 Materials The materials shall be multifilament fibres of Meta-aramid and meet the requirements as specified in this standard. 4.3 Mechanical properties 4.3.1 Sun light exposure After testing according to EN 6059-301 for 40 hours, the retention of the tensile strength shall be 45 % m
27、inimum with respect to the determined values of non-tested 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 t
28、o EN 6059-303, the retention of the 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
29、after a high temperature exposure test 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
30、be applied per dTEX shall not be less 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
31、The tests shall be carried out as shown in Table 2. For the number of samples, see EN 6049-001.
