Each member body interested in a subject for which a technical committee has been established has the right to be represented on
24、 that committee. International organizations, governmental and nongovernmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this do

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Direct

31、s materials used for the renovation of existing pipelines in a specified application area. System Standards for renovation deal with the following applications: ISO 11296: Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks; ISO 11297: Plastics piping sy
32、stems for renovation of underground drainage and sewerage networks under pressure (this document); 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 d
33、istinguished from those for conventionally installed plastics piping systems by the requirement to verify certain characteristics in the asinstalled condition, after site processing. This is in addition to specifying requirements for plastics piping system components as manufactured.Each of the Syst
34、em Standards comprises a: Part 1: General (this document)and all applicable renovation technique familyrelated parts, which for drainage and sewerage networks under pressure include or potentially include the following: Part 2: Lining with continuous pipes; Part 3: Lining with close-fit pipes; Part
35、4: Lining with cured-in-place pipes; Part 5: Lining with discrete pipes; Part 6: Lining with adhesive-backed hoses.The requirements for any given renovation technique family are specified in Part 1, applied in conjunction with the relevant other part. For example, this part of ISO 11297 and ISO 1129
36、73 specify the requirements relating to lining with close-fit 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 heading
37、s has been adopted for all parts of ISO 11297, in order to facilitate direct comparisons across renovation technique families.Figure 1 shows the common part and clause structure and the relationship between ISO 11297 and the System Standards for other application areas.vi ISO 2018 All rights reserve

39、 document specifies the requirements and test methods for plastics piping systems intended to be used for the renovation of underground drainage and sewerage networks under pressure, including both hydraulically and pneumatically pressurized systems. It is applicable to pipes and fittings, as manufa

It is not applicable to the existing pipeline or any non-structural sprayed coatings or annular filler.This document gives the general requirements common to all relevant renovation techniques.2 Normative referencesThe following documents are referr
