scope:

This Standard specifies the rubber insulated cables of rated voltages up to and including 450/750 V, more specifically, rubber or cross-linked polyvinyl chloride insulated and rubber or cross-linked polyvinyl chloride sheathed cords of rated voltage 300/300 V, for use in applications where high flexibility is required, for example for iron cords.

All cables should comply with the appropriate requirements given in JIS C 3663-1 and the individual types of cables should each comply with the particular requirements of this Standard.

NOTE 1 In this Standard, the electrical safety requirements for cross-linked poly-vinyl chloride material are deleted, since the safety of the said material is not fully established in Japan.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 60245-8: 2004 Rubber insulated cables-Rated voltages up to and including 450/750 V-Part 8: Cords for applications requiring high flexibility (MOD)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
