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 drains and sewers and water supply networks, which transport water intended for human consumption, including raw water pipelines.

u000b

It is applicable to polyethylene (PE) pipes, fittings and assemblies, as manufactured and as installed. It is not applicable to the existing pipeline.

u000b

It is applicable to the following technique families for renovation, intended to be used at an operating temperature of 20°C as the reference temperature:

u000bu000blining with continuous pipes;u000blining with close-fit pipes.u000bu000b

This document is applicable to the following technique families for trenchless replacement, intended to be used at an operating temperature of 20°C as the reference temperature:

u000bu000bpipe bursting and pipe extraction;u000bhorizontal directional drilling and impact moling.u000bu000b

NOTE For applications operating at constant temperatures greater than 20°C and up to 40°C, see ISO 4427-1:2019, AnnexA.

u000b

When used with lining with continuous pipes, lining with close-fit pipes and trenchless replacement technique families, this document is applicable to:

u000bu000bPE solid wall single layered pipes (nominal outside diameter, dn), including any identification stripes;u000bPE pipes with co-extruded layers on either or both the outside and inside of the pipe (total outside diameter, dn), as specified in AnnexD, where all layers have the same MRS rating.u000bu000b

Furthermore, when used with lining with continuous pipes and trenchless replacement this document is applicable to:

u000bu000bPE coated pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe (“coated pipe”), as specified in AnnexD.u000bu000b

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.
