Standards Development

Scope

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

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

b) 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).

Purpose

The proposed amendment will introduce the following changes;

- the possibility of using multi-material insulation systems,

- an upgraded Spark test regime,

- revised maximum dimensions,

- CPC conductor position and alternative core colours.
