BS 6004:2012+A1:2020

This British Standard specifies requirements and test methods for the construction and performance of cables that:

1. have a polyvinyl chloride (PVC) insulation of rated voltage 300/500 V;

2. are intended for electric power and lighting.

The types of cable included in this British Standard are:

• PVC insulated, PVC sheathed cable 300/500 V, single‑core 6181Y, flat‑twin 6192Y and 3‑core 6193Y (see Table 3);

• PVC insulated, PVC sheathed cable with circuit protective conductor, 300/500 V, single‑core 6241Y, flat‑twin 6242Y and 3‑core 6243Y (see Table 4);

• PVC insulated, PVC sheathed cable with or without circuit protective conductor, 300/500 V, single‑core 6192Y, 6241Y and flat‑twin 6242Y (alternative conductor versions) (see Table 5);

• ordinary duty low temperature PVC insulated, PVC sheathed flexible cable, 300/500 V, flat‑twin 3192A, circular‑twin 3182A, 3‑core 3183A, 4‑core 3184A and 5‑core 3185A (see Table 6).

The insulation and other components are suitable to permit operation of the cables at a maximum sustained conductor temperature of 70 °C and for a maximum short-circuit conductor temperature of 160 °C (for a maximum period of 5 s).

NOTE 1 Limitation on the temperature of the cables may be imposed in situations where they could be touched or where they could touch other materials.

NOTE 2 In installations that include wiring accessories, junction boxes and consumer units etc., the performance of these accessories should be taken into account in deciding the maximum operating temperature of the cable.

NOTE 3 Annex A provides a guide to the cross-referencing of the traditional United Kingdom Cable Codes (formerly known as the CMA codes) and harmonized CENELEC codes. Furthermore, Annex B gives information on the traditional UK cables transferred to BS EN 50525.

NOTE 4 Annex C gives guidance on the use of the cables specified in this British Standard.

NOTE 5 Annex D gives the compatibility test method.

NOTE 6 Annex E gives the voltage withstand test.

NOTE 7 Annex F gives notes on type tests.
