IEC 60245-1 pdf download – Rubber insulated cables – Rated voltages up to and including 450/750 V – Part 1: General requirements
1General1.1scope
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 IEC 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.

2 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
NOTEVulcanization is defined as a post-application treatment taking place after the insulation and/or 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
2.1.5
ethylene-propylene rubber compound(EPR) or equivalent synthetic elastomer
cross-linked compound in which the elastomer is ethylene-propylene or equivalent syntheticelastomer providing a compound with properties similar to EPR
2.1.6
cross-linked polyvinyl chloride (XLPvc)
combinations of materials of which polyvinyl chloride is the characteristic constituent,including adequate cross-inking agents，suitably selected，proportioned and treated which,when cross-linked, meet the requirements given in the particular specification
2.2Definitions relating to the tests
2.2.1
type testsi
tests required to be made before supplying a type of cable covered by this standard on ageneral commercial basis, in order to demonstrate satisfactory performance characteristics tomeet the intended application
NOTE These tests are of such a nature that,after they have been made，they need not be repeated，unlesschanges have been made in the cable materials or design which might change the performance characteristics.
2.2.2
sample testss
tests made on samples of completed cable,or components taken from a completed cable,adequate to verify that the finished product meets the design specifications
2.3
rated voltage
reference voltage for which the cable is designed,and which serves to define the electricaltests
NOTE 1 The rated voltage is expressed by the combination of two values: uo/u expressed in volts (v);
u。being the r.m.s. value between any insulated conductor and “earth”(metal covering of the cable or thesurrounding medium);
ubeing the r.m.s. value between any two phase conductors of a multicore cable or of a system of single-core
cables.
ln an alternating-current system, the rated voltage of a cable is at least equal to the nominal voltage of the systemfor which it is intended.
