ISO 21225-2:2018 specifies requirements and test methods for pipes and fittings which are part of plastics piping systems for the trenchless replacement of various underground pipeline networks, underground non-pressure and pressure drainage and sewerage networks and underground water and gas supply networks, by means of horizontal directional drilling and impact moling.<\/p>\n

ISO 21225-2:2018 is applicable to polyethylene (PE) pipes and fittings, as manufactured, as well as to the installed replacement system.<\/p>\n

ISO 21225-2:2018 is intended to be used in conjunction with standards applicable for the construction of PE pipeline systems where available.<\/p>\n

Regarding manufactured pipes it is applicable to three different PE pipe types:<\/p>\n

– PE solid wall single layered pipes (nominal outside diameter, dn), including any identification stripes;<\/p>\n

– 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;<\/p>\n

– PE pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe ("coated pipe"), see Annex A.<\/p>\n

In addition, ISO 21225-2:2018 is applicable to:<\/p>\n

– jointing of pipe lengths by means of butt fusion joint to form continuous strings prior to installation;<\/p>\n

– fabricated and injection-moulded fittings made of PE.<\/p>\n

Pipes made from other plastics, e.g. polypropylene (PP) are outside the scope of this document.<\/p>\n

ISO 21225-2:2018 is not applicable to push-fit jointed discrete pipes assembled as part of the trenchless installation process.<\/p>\n","protected":false},"excerpt":{"rendered":"
