This standard 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 polyethylene piping systems. It applies to piping systems in polyethylene (PE) materials for different application fields, such as water and gas supply, water distribution, irrigation and gaseous fuel systems.
The malleable cast iron fittings specified in this standard are of compression end type for the connection of PE pipes or of transition type with combined compression ends for pipes in different materials or with combined compression and threaded ends in conformance with prEN 10226-1. Their range of sizes covers nominal outside diameters of PE pipes dn 16 to dn 125 mm and pipe thread sizes 1/2 to 4.
