Requirements for design, testing and performance of fittings made of malleable cast iron with compression ends for polyethylene piping systems are defined. Applicable to piping systems in (PE) polyethylene materials for different application fields, such as gas and water supply, water irrigation, distribution and gaseous fuel systems. The fittings defined 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. Range of sizes cover nominal outside diameters of PE pipes dn 16 to dn 125mm and pipe thread sizes 1/2 to 4.
