20、 6722-2:2013ISO 6722-2:2013(E) Introduction ISO 6722 deals with single-core cables, with copper conductor cables covered in ISO 6722-1 and aluminium conductor cables covered in this part of ISO 6722. The performance of aluminium conductor cables is, in general, not to be expected to be the same as t

21、he performance of copper conductor cables in a one-to-one comparison basis.

23、 the applicability of regulatory limitations prior to use. 1 Scope This part of ISO 6722 specifies the dimensions, test methods, and requirements for single-core 60 V cables intended for use in road vehicle applications where the nominal system voltage is 60 V d.c. or 25 V a.c. It also specifies add

24、itional test methods and/or requirements for 600 V cables intended for use in road vehicle applications, where the nominal system voltage is from 60 V d.c. or 25 V a.c. to 600 V d.c. or 600 V a.c. It also applies to individual cores in multi-core cables. This part of ISO 6722 specifies requirements
