11、5:2005 3 1 Scope This standard defines the characteristics of post installation flexible mechanical protection sleeves for electrical cable and cable bundles made from meta-aramid fibres and provided with a water repelled protection. 2 Normative references The following referenced documents are indi

12、spensable for the application 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 6049-001, Aerospace series Electrical cables, installation Protection sleeve in meta-aram

13、id fibres Part 001: Technical specification. 1)EN 6059-*, Aerospace series Electrical cables, installation protection sleeve Test methods. 1)3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 6049-001 and the following apply. 4 Requirements 4.1 Compositi

14、on and mass 4.1.1 Composition of the tows Each tow shall be built-up of 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 and braiding angle) of the sleeve, see 4.1.2. The thick

15、ness of the tow shall 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 weaving of tows and the closing mechanism shall applied so that the sleeves mee

16、t the requirements for dimensions, coverage and mass. The closing system shall be a hook and loop system. The weaving pattern of the tows shall be in such a way that the coverage is minimum 90 % for all sizes. Figure 1 and Table 1 give the composition and the dimensions of the sleeve. *All its parts

The closing mechanism shall be a suitable material which fulfil the requir

21、ements of this specification. 4.3 Mechanical properties 4.3.1 Temperature range The operation temperature of the protection sleeves shall be: Maximum: 175 C, Minimum: 55 C. 4.3.2 Sun light exposure After testing according to EN 6059-301 for 40 hours, the retention of the tensile strength shall be 45

22、 % minimum with respect to the determined values of non-tested tows. 4.3.3 Bending properties Bending of the minimum radius of five times of the nominal diameter as specified in EN 6059-402, shall be possible under the conditions mentioned in 4.3.4. 4.3.4 Locking of the closing system The locking of

23、 the closing system shall be so that opening and closing is possible by hand. If closed around a cable bundle which is 80 % of the nominal inner diameter of the sleeve, the mechanism shall be in a closed position. 4.3.5 Resistance to fluids After testing according to EN 6059-303, the locking mechani

24、sm shall not be damaged and the retention of the tensile strength shall be 90 % minimum with respect to the determined values of non-tested tows. 4.3.6 Water absorption To fulfil the requirements for water absorption, the sleeve shall repel water as tested in EN 6059-305 for six hours. This test sha

25、ll be executed after a high temperature exposure test according to EN 6059-302. 4.3.7 Mould growth After tested in accordance with EN 6059-306, there shall no external deterioration which would affect service use and no mould growth visible to the naked eye. 4.3.8 Tensile strength of tows The tensil

26、e force to 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 Te

27、st methods The tests shall be carried out as shown in Table 2. For the number of samples to be tested, see EN 6049-001.
