prBAS EN 10344:2027

This document specifies the requirements for the design, performance and testing of fittings made of malleable cast iron (see also Clause 5, Materials) with compression ends for steel pipes. This document applies to steel piping systems for different application fields, such as supply and distribution of gas, water for general purposes (e.g. irrigation) as well as for human consumption, aqueous liquids and pressurized air. This document contains requirements and tests relating to compression fittings which can be connected to smooth walled steel pipes. The fittings can also incorporate other types of connection, such as threaded ends in conformance with EN 10226-1, flanged ends, compression ends for connection for pipes other than steel, and can also take on various structural shapes, such as straight adaptor piece, elbow or T-piece. Their range of sizes covers nominal sizes DN 10 to DN 100 (fitting size 3/8 to 4).
