Foreword

GB/T 5023 "rated voltage 450/750V and below PVC insulated cables" is divided into seven parts.

--- Part 1. General requirements;

--- Part 2. Test methods;

--- Part 3. Non-sheathed cables for fixed wiring;

--- Part 4. Sheathed cables for fixed wiring;

--- Part 5. Flexible cables (cords);

--- Part 6. Lift cables and cables for flexible connection;

--- Part 7. two-core or multi-core shielded and unshielded cable.

This section GB/T 5023 Part 7. This section identical with IEC 60227-7:2003 "rated voltage 450/750V and with Under PVC insulated cables Part 7. two-core or multi-core shielded and unshielded cables soft "version 1.1 (in English).

For ease of use, GB/T 5023 made this part of the following editorial changes.

"." --- With a decimal point instead of a comma as the decimal point, "";

--- Remove the IEC 60227-7:2003 Foreword.
