ECISS/TC 29/SC 3/WG 3 - Malleable cast iron fittings

Deletion of the Clause 12 "Quality assurance system" and creation of an informative annex with the text of Clause 12.

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.

This standard specifies the requirements for the design and performance of threaded pipe fittings in malleable cast iron. These fittings are for general purposes for the transmission of fluids and gases up to the limits of pressure and temperature specified in this standard. They are intended for the connection  of elements threaded in accordance with ISO 7-1, sizes 1/8 to 6. For use in conditions outside the pressure and temperature limits specified, reference shall be made to the manufacturer.
