21、of this standard, the terms and definitions given in ISO 8815 and EN 3475-100 apply. 4 Materials and construction of cables 4.1 General The composition, dimensions and mass of the cable shall conform to the characteristics below, as well as the values specified in the product standards. The individu
22、al cores shall conform to EN 2083 or EN 4434, EN 2084 and the product standards. *And all parts quoted in this standard. 1) Published as ASD Prestandard at the date of publication of this standard. EN 3375-001:20075 4.2 Materials The materials shall conform to the product standard. The surface of co
23、nductive materials used shall be free from corrosion and other contamination. Insulation and others materials shall have no corrosive effect upon the conductors and screens and shall not be susceptible to attack by mould and other micro-organisms. 4.3 Construction of cables 4.3.1 General The permiss
24、ible operating temperature of conductors shall not be lower than the maximum operating temperature of the cable as a whole. 4.3.2 Cabled cores The lay length of the outer lay shall not be less than eight times and not more than 16 times the nominal diameter of the cabled cores, except if a different
25、 value is necessary to maintain the required characteristics. The core shall not be spliced. Where filler cores are used, this shall be specified in the product standard. The assembly may be held together with an overall wrap. 4.3.3 Screened cables 4.3.3.1 General The construction shall conform to t
26、he product standard. Depending on protection level, the screening may be composed of: one or several spiral layers; one or several braids made using strands or strips; one or several metallic or other strips; one or several layers of extruded conductive or non-conductive materials; a combination of
27、the above. The screening may be individual and/or overall. The individual strands or strips used for the screen shall be free from kinks, loops or breaks. Except when particular materials are used, they shall conform to standard EN 2083 or EN 4434 or shall satisfy the mechanical tests in EN 3475-505
28、 to EN 3475-508 before use. Where spiral screening is used, the first lay direction shall be contrary to that of the cabled cores. 4.3.3.2 Joints Splices of the individual strands or strips may be affected by brazing, soldering or folding in. There shall be no more than one splice per 3 m cable leng
29、th (measured between different individual strands or strips). EN 3375-001:20076 4.3.3.3 Braid screen pushback capability In accordance with Table 1, test 6.49. 4.3.3.4 Angle of spiral screening or braiding The angle of spiral screening or braiding (as shown in Figure 1 of EN 2235), measured against
30、the longitudinal axis of the cable shall be at least 10, except if a different value is necessary to maintain the required characteristics. 4.3.3.5 Screen coverage Coverage , if specified, is determined in accordance with EN 2235. 4.3.4 Outer jacket The construction shall conform to the product stan
