scope:

This specification describes the construction, identification and testing of wires and cables for the internal wiring of electronic or other equipment.

These wires and cables (ie screened wires) are also used as the cores of multicore cables.

The insulation of the wires and the sheathing of cables in this specification present a limited fire hazard and produce limited levels of noxious fumes, smoke and corrosive products when assessed by the methods of test in this specification.

These wires and cables are required to meet the Relative Thermal Life and Temperature Index test of BS G230 Appendix C for 40,000h at 120˚C.

These wires and cables are suitable for continuous use within a temperature range of -50˚C to 120˚C.

These wires and cables have a voltage rating of 600 V rms or 800V DC.

These wires and cables are suitable for soldered or crimped terminations. They are not designed or necessarily suitable for solderless wrapped electrical connections.

Although these wires and cables may be subjected to test contamination by one or more of the fluids listed in BS G230 Table 3 and Table E of this Standard, attention is drawn to 2.2.2 and 2.2.2.1.

Stranded conductors shall be used for flexing applications. For fixed applications stranded or solid conductors may be used.

The following minimum bend radii shall be used within equipment:

For flexing applications, 10 times the overall diameter of the wire or cable.

For fixed applications, 4 times the overall diameter of the wire or cable.
