Resumen

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation by means of renovation and trenchless replacement of underground non-pressure and pressure drainage and sewerage networks and water supply networks, which transport water intended for human consumption, including raw water pipelines. It is applicable to polyethylene (PE) pipes, fittings and assemblies, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation: — lining with continuous pipes; — lining with close-fit pipes; and technique families for trenchless replacement: — pipe bursting and pipe extraction; — horizontal directional drilling and impact moling. and intended to be used at an operating temperature of 20 °C as the reference temperature. NOTE For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see ISO 4427 1:2019, Annex A. When used with lining with continuous pipes, lining with close-fit pipes and trenchless replacement technique families, this document is applicable to: PE solid wall single layered pipes, (nominal outside diameter, dn), including any identification stripes; PE pipes with co-extruded layers on either or both the outside and inside of the pipe (total outside diameter, dn), as specified in Annex E, where all layers have the same MRS rating. Furthermore, when used with lining with continuous pipes and trenchless replacement this document is applicable to: — PE coated pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe (“coated pipe”), as specified in Annex E. This document is applicable to jointing by means of butt fusion and electrofusion and to fabricated and injection-moulded fittings and mechanical connections of PE.
