The objective of this European Standard is to achieve safe operation of corrugated metal gas hose assemblies by specifying the requirements of performance, materials and test methods. The corrugated metal gas hose assemblies as specified are suitable for the connection of domestic appliances inside or outside a dwelling, using gas at a pressure lower than 0,5 bar. These assemblies are designed for the use with movable appliances; they may also be used for the connection of fixed appliances. The term gas relates to a first, second or third family gas as referred to in EN 437, Table 1. These gases are commonly referred to as manufactured gases, natural gases or petroleum gases (LPG).
