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 polyethylene piping systems.
This document applies to piping systems in polyethylene (PE) materials for different application fields, such as water and gas supply, water distribution, irrigation, aqueous liquids, pressurized air and gaseous fuel systems.
NOTE Products complying with this document used for water applications intended for human consumption are expected to comply with the relevant national, regional or local regulatory provisions applicable in the place of use. Due to the variety and dynamic of the requirements, it is advisable to check the compliance.
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 EN 10226-1. Their range of sizes covers nominal outside diameters of PE pipes dn 16 mm to dn 110 mm (DN 10 to DN 100) and pipe thread sizes ⅜ to 4.
