This specification covers polyvinyl chloride insulated single conductor electric wires made with tin-coated copper conductors or silver-coated copper alloy conductors. The polyvinyl chloride insulation of these wires may be used alone or in combination with other insulating or protective materials. Classification The wires shall be as described in the applicable detail specification. Part Numbers Part numbers under this specification are coded as in the following example: Temperature Rating of Finished Wire The maximum conductor temperature of the finished wire for continuous use shall be as specified in the applicable detail specification (see 6.1.1). Voltage Rating of Finished Wire Voltage rating of an insulation system is specified in the detail specification. Polyvinyl chloride insulation systems specified herein has been used in aerospace applications using 115 V (phase to neutral)@ 400 H AC@ and 28 V DC. Verification of the suitability of this product for use in other electrical system configurations is the responsibility of the user.
