Specifies the requirements for insulating, sheathing and covering materials that are used for harmonized low voltage energy cables.

EN 50363 contains, in its various 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 conjunction 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. Table 1 ― Parts for EN 50363 Part number Title Compounds included 0 General introduction - 1 Cross-linked elastomeric insulating compounds EI 2, EI 3, EI 4, EI 6, EI 7 2-1 Cross-linked elastomeric sheathing compounds EM 2, EM 3, EM 4, EM 6, EM 7, EM 9 2-2 Cross-linked elastomeric covering compounds EM 5 3 PVC insulating compounds TI 1, TI 2, TI 3, TI 4, TI 5 4-1 PVC sheathing compounds TM 1, TM 2, TM 3, TM 4, TM 5, 4-2 PVC covering compounds TM 6 5 Halogen-free, cross-linked insulating compounds EI 5, EI 8 6 Halogen-free, cross-linked sheathing compounds EM 8, EM 10 7 Halogen-free, thermoplastic insulating compounds TI 6, TI 7 8 Halogen-free, thermoplastic sheathing compounds TM 7 9-1a Miscellaneous insulating compounds – Cross-linked polyvinyl chloride (XLPVC) XI 1 10-1a Miscellaneous sheathing compounds – Cross-linked polyvinyl chloride (XLPVC) XM 1 10-2 Miscellaneous sheathing compounds – Thermoplastic polyurethane TMPU aThis part is proposed for withdrawal. Materials for use specifically in utility power cables are not covered by this EN. They can be found in HD 603, HD 604, HD 620, HD 621, HD 622, HD 626 and HD 627. Materials for use specifically in communications cables are the responsibility of CENELEC TC 46X. At present such materials are given in EN 50290-2-20 to -2-30 inclusive.
