Specification for insulating and sheathing materials for cables -- Cross-linked elastomeric insulating compounds
This section of BS 7655 specifies the requirements for the flame retardant composite cross-linked elastomeric insulating compound listed in Table 1. The relevant test methods are given in BS EN 60811 and BS 6469.
These compounds are for use on coil end leads conforming to BS 6195, but may be used for other suitable applications as detailed in the cable specification.
This section is to be read in conjunction with BS 7655-0, which contains essential provisions for the application of this section of BS 7655.
Table 1 – Type of flame retardant cross-linked insulation
| Type | Maximum material operating temperature °C | General application |
