IEC 60245-1 pdf download Rubber insulated cables – Rated voltages up to and including 450/750 V – Part 1: General requirements
1 General
1.1scope
This part of lEC 60245 applies to rigid and flexible cables with insulation, and sheath if any,based on vulcanized rubber of rated voltages u,/u up to and including 450/750 V used inpower installations of nominal voltage not exceeding 450/750 V a.c.
NOTE For some types of flexible cables the term ‘cord’ is used.
The particular types of cables are specified in lEC 60245-3，IEC 60245-4，etc.
The codedesignations of these types of cables are given in Annex A.
The test methods specified in Parts 1 to 8 are given in lEC 60245-2,IEC 60332-1 and in therelevant parts of lEC 60811.

Terms and definitions
For the purposes of this document, the following terms and definitions apply:
2.1 Definitions relating to insulating and sheathing materials
2.1.1
type of compound
category in which a compound is placed according to its properties, as determined by specifictests
NOTE The type designation is not directly related to the composition of the compound.
2.1.2
rubber compound
combination of materials suitably selected, proportioned, treated and vulcanized, of which thecharacteristic constituent is a rubber and/or synthetic elastomer
NOTE Vulcanization is defined as a post-application treatment taking place after the insulation andlor sheath hasbeen applied in order to induce permanent cross-linking of the elastomer.
2.1.3
polychloroprene compound (PCP) or other equivalent synthetic elastomer
vulcanized compound in which the elastomer is polychloroprene or other equivalent syntheticelastomer providing a compound with properties similar to PCP
2.1.4
ethylene-vinyl acetate rubber compound(EVA) or other equivalent synthetic elastomercross-linked compound in which the elastomer is ethylene-vinyl acetate or other equivalentsynthetic elastomer providing a compound with properties similar to EVA
