BS 7540-2:2005 provides guidance for equipment manufacturers, installers and end-users on the properties of low voltage electric cables, and the limitations that are deemed to be necessary in order to safeguard life, buildings and goods.
The information is given in the form of limiting values and is illustrated by examples, which are not exhaustive but which indicate ways by which safety can be obtained.
This part of BS 7540 provides guidance for the safe use of electric cables with a rated voltage not exceeding 450/750 V. It is applicable to those cable types that are specified in Harmonized Documents HD 21 and HD 22 as implemented in BS 638-4, BS 6004, BS 6007, BS 6500, BS 7211 and BS 7919.
NOTE: These British Standards also specify requirements for cable types that are specific to the United Kingdom and are not included in HD 21 or HD 22. Guidance on these cables is given in BS 7540-3. The classes of external influence (environmental conditions) used in this part of BS 7540 are as listed in BS 7540-1:2005.
BS 7540-2:2005 supersedes BS 7540:1994 which is withdrawn.
