It has been technically approved by the experts of the concerned Domain following member comments. Subsequent to the publication of this Prestandard, the te
5、chnical content shall not be changed to an extent that interchangeability is affected, physically or functionally, without re-identification of the standard. After examination and review by users and formal agreement of ASD-STAN, it will be submitted as a draft European Standard (prEN) to CEN (Europ
6、ean Committee for Standardization) for formal vote and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national level by giving the EN the status of a national standard and by withdrawing any national standards conflicting with the EN. Edition

13、t 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 thickness of the tow shall be so that the finished sleeve meet the mechanical and environmental req
14、uirements. 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 meet the requirements for dimensions, coverage and mass. The closing system shall be a hook and l
15、oop 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 quoted in this standard. 1) Published as AECMA Prestandard as the date of publication of this

18、ements as specified in this standard. The closing mechanism shall be a suitable material which fulfil the requirements 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
19、 exposure After testing according to EN 6059-301 for 40 hours, the retention of the tensile strength shall be 45 % 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 6059-40
20、2, shall be possible under the conditions mentioned in 4.3.4. 4.3.4 Locking of the closing system The locking of 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
21、 be in a closed position. 4.3.5 Resistance to fluids After testing according to EN 6059-303, the locking mechanism 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 requi
22、rements for water absorption, the sleeve shall repel water as tested in EN 6059-305 for six hours. This test shall 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
23、would affect service use and no mould growth visible to the naked eye. 4.3.8 Tensile strength of tows The tensile 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 paragrap
24、h. 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 the number of samples to be tested, see EN 6049-001. prEN 6049-005:20056 Table 2 Test methods and details EN 6059- Design
