適用范圍：This British Standards specifies requirements for design and performance of threaded pipe fittings in malleable cast iron and cast copper alloy for two basic designs:1) category 1: BS 143 design and BS 1256 design, in a limited range range of malleable cast iron fitting sizes and types with threads conforming to BS 21(ISO 7-1), and that are not included in BS EN 10242;2) category 2: BS 143 design only, in a full fange of malleable cast iron fitting sizes and types with threads conforming to ANSI/ASME B1.20.1 (NPT);3) category 3: BS 143 design only, in a limited range of cast copper alloy fitting sizes and types, with threads conforming to BS 21 (ISO 7-1) or ANSI/ASME B1.20.1 (NPT).These fittings are for general purposes for transmission of fluids and gases up to the limits of pressure and temperature specified in this British Standard. They are intended for connection of elements with threads conforming to BS 21 (ISO 7-1) or ANSI/ASME B1.20.1 (NPT), in sizes 1/8 to 6 for malleable cast iron fittings and sizes 1/8 to 2 for cast copper alloy fittings.
