28、DIN EN ISO 11299-3:2013-05 EN ISO 11299-3:2013 (E) 3 IntroductionThis part of ISO 11299 is part of a system standard for plastics piping systems of various materials used for the renovation of existing pipelines in a specified application area. System standards for renovation deal with the following
29、 applications: plastics piping systems for renovation of underground non-pressure drainage and sewerage networks; plastics piping systems for renovation of underground drainage and sewerage networks under pressure; plastics piping systems for renovation of underground water supply networks; plastics
30、 piping systems for renovation of underground gas supply networks (this application).These system standards are distinguished from those for conventionally installed plastics piping systems because they set requirements for certain characteristics in the as-installed condition, after site processing
31、. This is in addition to verification of characteristics of plastics piping systems as manufactured.This system standard comprises a Part 1: General and all applicable parts relating to the renovation technique family, from the following: Part 2: Lining with continuous pipes Part 3: Lining with clos
32、e-fit pipes (this document) Part 4: Lining with cured-in-place pipes Part 6: Lining with adhesive-backed hosesThe requirements for any given renovation technique family are specified in this part of ISO 11299 and are applied in conjunction with the relevant other part. For example, both ISO 11299-1
33、and this part of ISO 11299 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 str
34、ucture of clause headings has been adopted for all parts of ISO 11299, in order to facilitate direct comparisons across renovation technique families.Figure 1 illustrates the common part and clause structure and the relationship between ISO 11299 and the system standards for other application areas.
