Provides requirements suitable for aircraft general purpose cables from which requirements for specific cables may be obtained for inclusion in the relevant individual cable detailed specification. Includes designation of the cable, packaging and labelling, formulae for calculating braiding details, manufacturers' identification marks, dimensions of ferrule for hot kerosine test and pliability tests.

This British Standard specifies a number of requirements applicable to aircraft general purpose cables from which requirements for specific cables may be selected for inclusion in the relevant individual cable detailed specification.
