35、ittings which are part of plastics piping systems for the trenchless replacement of underground non-pressure and pressure drainage and sewerage networks and underground water and gas supply networks, by means of pipe bursting and pipe extraction.It is applicable to polyethylene (PE) pipes and fittin
36、gs, as manufactured, as well as to the installed replacement system.This document is intended to be used in conjunction with standards applicable for the construction of PE pipeline systems where available.Regarding manufactured pipes it is applicable to three different PE pipe types: PE solid wall
37、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 pipes (outside diamete
38、r, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe (“coated pipe”), see Annex A.In addition it is applicable to: jointing of pipe lengths by means of butt fusion joint; jointing of pipe lengths by means of electrofusion joint; fabricated and injection-mo
39、ulded fittings made of PE.Pipes made from other plastics, e.g. glass reinforced plastics (GRP), are outside the scope of this document.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
