14、0:2011 4 Introduction EN 50363 contains, in its various parts, the requirements for insulating, sheathing and covering materials that are used for harmonized low voltage energy cables in EN 50525. The previous edition of EN 50363-0 (2005) showed, in its Annex A, the original location in HD 21 and HD
15、 22 of each material and its place in the full series of EN 50363. For this second edition, this annex has been deleted. The content of EN 50363 is not, and will not be, restricted only to materials for cables to EN 50525. Other materials for harmonized LV industrial cables may be included. Furtherm
16、ore, the use of materials in EN 50363 for cables outside EN 50525 is not prohibited, but it is strongly recommended that expert advice be taken before such use, or before any proposal for incorporation into another standard. BS EN 50363-0:2011 5 EN 50363-0:2011 1 Scope EN 50363 contains, in its vari
17、ous parts, the requirements for insulating, sheathing and covering materials that are used for harmonized low voltage energy cables. EN 50363 is published as this Part 0 together with a series of separately published parts as listed in Table 1 and these parts require that Part 0 be read in conjuncti
18、on with them. It also includes a list of the test methods called up in the particular parts of the standard, with references to the current editions of other standards in which the relevant test methods are given.

43、otherwise stated in the standard for the particular cable, the tests on insulation shall be made on samples from each core if the cable has one, two or three cores; and on samples from three cores (of differing colours if any) if the cable has more than three cores, with samples taken not less than
44、16 h after extrusion, and crosslinking if appropriate. 4.2.2 Sheath Samples shall be taken not less than 16 h after extrusion, and cross-linking if appropriate. 4.3 Ambient temperature Tests shall be made at an ambient temperature within the range 5 C to 35 C unless otherwise specified in the detail
45、s for the particular test. 5 Requirements The requirements for the various types of compound have been drafted such that conformity can be checked by testing samples taken from finished cable. NOTE In earlier standards for materials, requirements for compatibility and for resistance to impact at low
46、 temperature were included. These are now shown, as part of the requirements for the particular cable, for instance in EN 50525.
