Gives construction and performance requirements for a range of PTFE insulated cables and wires with either silver plated or nickle plated copper conductors suitable to be used in electrical instruments and equipment.

This British Standard specifies the construction and performance requirements for a range of PTFE insulated cables and wires with either silver plated or nickel plated copper conductors which are suitable for use in electrical instruments and equipment. The continuous current ratings for the cables are given in Annex A.

The following types of cables are specified:

NOTE 1 Cables with nickel plated conductors are prefixed N.

NOTE 2 The cables are suitable for use where the potential between conductors, or between a conductor and screen, or between a conductor and the equipment structure does not exceed the voltage specified above for each type.

NOTE 3 The cables are suitable for continuous use where the maximum stabilized conductor temperature does not exceed 190 °C (cables having silver plated conductors) or 260 °C (cables having nickel plated conductors). They are suitable for applications not involving continuous flexing at temperatures down to − 75 °C, or, where continuous flexibility is involved, at temperatures down to − 50 °C.

NOTE 4 Although cables having silver plated conductors are suitable for use up to 190 °C, it should be noted that after prolonged use at this temperature the conductor may tarnish, with consequent difficulty in soldering.

NOTE 5 The latest revision of an Aerospace Series standard is indicated by a prefix number.
