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.

22、of ISO 6722 may involve hazardous materials, operations, and equipment. This part of ISO 6722 does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this part of ISO 6722 to establish appropriate safety practices and determine
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
25、for aluminium conductor cables. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
