SUMMARY OF TOPICS
The following changes in requirements to the Standard for Polyvinyl Chloride, Polyethylene, and Rubber Insulating Tape, UL 510, are being proposed for preliminary review and comment only:
1. For Preliminary Review Only: UL is proposing a tenth edition of the Standard for Polyvinyl Chloride, Polyethylene, and Rubber Insulating Tape, ANSI/CAN/UL 510, as an American National Standard and National Standard of Canada. In the US, this Standard covers: (a) Thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80°C (176°F) and lower temperatures on joints and splices in wires and cables in accordance with NFPA 70. 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. (b) The characteristic constituent of the thermoplastic tape covered in this Standard is either PVC (polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate), or PE (thermoplastic polyethylene). In Canada, this Standard covers: (a) Thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and 80°C (176°F) on joints and splices in wire and cables in accordance with CSA C22.1. 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. (b) The characteristic constituent of the thermoplastic tape covered in this Standard is PE (thermoplastic polyethylene). Requirements for PVC tape are covered by CSA C22.2 No. 197.
