ISO6722

     This International Standard 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 u (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 > (60 V d.c. or 25 V a.c.) to u (600 V d.c. or 600 V a.c.). It also applies to individual cores in multi-core cables.

它还适用于多芯电缆的单个芯线。

也就是说可以做为多芯电缆的绝缘使用，应该是这个意思吧。
