Bibliography

Describes the test methods to be used for testing polymeric insulated and sheathed electric cables, of rated voltage up to and including 19/33 kV, intended for public distribution systems, and for use in power generating plants and sub-stations.

BS7870‑2 collates and specifies the test methods to be used for testing polymeric insulated and sheathed electric cables, of rated voltage up to and including 19/33kV, intended for public distribution systems, and for use in power generating plants and sub-stations.

The test methods in this part of BS7870 are additional to those already harmonized, e.g. in the BSEN60332 series and the BSEN60811 series, and are for use for testing cable types specified in BS7870‑3, BS7870‑4 and BS7870‑5. In each case, these standards give complementary information needed for the practical application of the test method to each specific type of cable. Therefore BS7870‑2:2011, as such, is not sufficient for carrying out and evaluating the tests on electric cables.

Full test conditions (e.g. temperatures, durations) and/or requirements to be met are not specified in this standard. Such data needed to carry out the tests is given in the particular sections of BS7870.

NOTE The words “particular section” refer throughout to the individual sections of BS7870 in which particular cable types are specified.
