This British Standard specifies requirements for the construction, dimensions and mechanical and electrical properties of insulated flexible cables for operation at voltages up to and including 450 V a.c. to earth and 750 V a.c. between conductors, intended for use with appliances and equipment in industrial or similar environments for ordinary or heavy duty.
A guide to the use of the cables specified in this standard is given in Annex A. Guidance to manufacturers on procedures for routine testing is given in Annex B. Test methods are given in Annex C, Annex D, Annex E, Annex F, Annex G, Annex I and Annex K.
The types of cables included in this standard are as follows:
