Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks. Lining with continuous pipes | Status: Project Underway, Current

1 Scope This document, in conjunction with ISO 11296‑1, specifies requirements and test methods for pipes and fittings which are part of plastics piping systems installed as continuous pipes in the renovation of underground non-pressure drainage and sewerage networks. It is applicable to polyethylene (PE) pipes of three different types:

• — 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 A, where all layers have the same MRS rating;
• — PE coated pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe (“coated pipe”), see Annex A.

In addition it covers:

• — jointing of pipe lengths by means of butt fusion;
• — fabricated and injection-moulded fittings made of PE.
