This document specifies the requirements and test methods for plastics piping systems intended to be
used for the renovation of underground gas supply networks. It is applicable to pipes and fittings, as
manufactured, as well as to the installed lining system. It is not applicable to the existing pipeline or
any sprayed coatings or annular filler.
This document gives the general requirements common to all relevant renovation techniques.

This document, read in conjunction with Part 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 gas supply 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...view more
