This standards covers thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80C (176 F) and lower temperatures on joints and splices in wires and cables in accordance with the National Electrical Code. It is intended that rubber tape on a joint or splice be mechanically protected by a covering such as friction tape . Thermoplastic tape is acceptable without the additional mechanical protection.

This standard specifies requirements and dimensions for PVC insulated cables for operation at nominal voltages up to and including 1900 V to armour or earth and 3300 V between conductors.
