ISO 6722-2:2013 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 additional 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. ISO 6722-2:2013 specifies requirements for aluminium conductor cables.
