21、SO 112972:2018ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject
22、for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) o
23、n all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted
24、. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying an

System standards for reno
29、vation dealing with the following applications are either available or in preparation: ISO 11296, Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks; ISO 11297, Plastics piping systems for renovation of underground drainage and sewerage networks under p
30、ressure (this application); ISO 11298, Plastics piping systems for renovation of underground water supply networks; ISO 11299, Plastics piping systems for renovation of underground gas supply networks.These system standards are distinguished from system standards for conventionally installed plastic
31、s piping systems by the requirement to verify certain characteristics in the “as installed” condition, after site processing. This is in addition to verification of characteristics of plastics piping systems “as manufactured”.Each of the system standards comprises a: Part 1: Generaland all applicabl
32、e renovation technique family-related parts, which for drainage and sewerage networks under pressure include or potentially include the following: Part 2: Lining with continuous pipes (this document) Part 3: Lining with close-fit pipes Part 4: Lining with cured-in-place pipes Part 5: Lining with dis
33、crete pipes Part 6: Lining with adhesive-backed hosesThe requirements for any given renovation technique family are specified in Part 1, applied in conjunction with the relevant other part. For example, both ISO 11297-1 and this document, together specify the requirements relating to lining with con
34、tinuous pipes. For complementary information, see ISO 11295. Not all technique families are pertinent to every area of application and this is reflected in the part numbers included in each system standard.A consistent structure of clause headings has been adopted for all parts to facilitate direct
35、comparisons across renovation technique families.Figure 1 shows the common part and clause structure and the relationship between ISO 11297 and system standards for other applications.Annex A of this document is normative.

37、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 drainage and sewerage networks under pressure. It is applicable to polyethylene (PE) pipes of three different types: PE solid wall s
38、ingle layered pipes (nominal outside diameter, dn), including any identification stripes; PE pipes with coextruded 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 di
39、ameter, 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 injectionmoulded fittings made of PE.It is applicable to PE pipes, fittings and a
40、ssemblies intended to be used at an operating temperature of 20 C as the reference temperature.NOTE For applications operating at constant temperatures greater than 20 C and up to 40 C, see ISO 44271:2007, Annex A.2 Normative referencesThe following documents are referred to in the text in such a wa
