Gas welding equipment. Hose connections for equipment for welding, cutting and allied processes (British Standard)
This European Standard lays down the dimensions and specifies the characteristics of the constituent parts of hose connections for welding, cutting and allied processes, for example for pressure regulators according to EN ISO 2503 and blowpipes. This European Standard does not cover the design of the part of the hose tail inserted into the hose. This is specified in EN 1256.
