Standards

This specification covers poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for water (see Appendix X1). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.

This specification covers poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.

This standard specifies attachment fused and unfused plugs (caps), shuttered receptacles (sockets) for flush surface mounting. These plugs and sockets are suitable for alternating current circuits only of voltages not exceeding 250 volts and currents not exceeding 15 amperes.  The plugs and receptacles covered by this standard are intended for use in making readily detachable electrical connections in non-hazardous locations between supply circuits and portable lamps, appliances and similar equipment.

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 British Standard specifies requirements for the construction dimensions and mechanical and electrical properties of non- armoured polyvinyl chloride (PVC) insulated cables for operation at voltages up to and including 450 V a.c. to earth and 750 V a.c between conductors, intended for electric power lighting and internal wiring.
