26、lastics 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 applications: Plastics piping systems for renovation of underground non-pressure drainage and sewerage networks; Plastics
27、 piping systems for renovation of underground water supply networks; Plastics piping systems for renovation of underground gas supply networks; Plastics piping systems for renovation of underground drainage and sewerage networks under pressure. These System Standards are distinguished from those for
28、 conventionally installed plastics piping systems by the requirement to verify certain characteristics in the as-installed condition, after site processing. This is in addition to specifying requirements for plastics piping systems components as manufactured. This System Standard comprises a: Part 1
29、: General and all applicable renovation technique family-related parts from the following: Part 2: Lining with continuous pipes Part 3: Lining with close-fit pipes Part 4: Lining with cured-in-place pipes Part 6: Lining with adhesive-backed hoses The requirements for any given renovation technique f
30、amily are given in part 1, applied in conjunction with the relevant other part. For example, ISO 11298-1 and this part of ISO 11298 together specify the requirements relating to lining with close-fit pipes. For complementary information, see ISO 11295. Not all technique families are pertinent to eve
31、ry 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 of ISO 11298, in order to facilitate direct comparisons across renovation technique families. Figure 1 shows the common part and
32、 clause structure and the relationship between ISO 11298 and the System Standards for other application areas. 4DIN EN ISO 11298-3:2011-07 EN ISO 11298-3:2011 (E) Figure 1 Format of the renovation System Standards 5DIN EN ISO 11298-3:2011-07 EN ISO 11298-3:2011 (E) 1 Scope This part of ISO 11298, in
33、 conjunction with ISO 11298-1, specifies requirements and test methods for close-fit lining systems intended to be used for the renovation of water supply networks, which transport water intended for human consumption, including raw water intake pipelines. It is applicable to polyethylene (PE) pipe
34、for both independent and interactive pressure pipe liners as well as associated fittings and joints for the construction of the lining system. 2 Normative references The following referenced documents are indispensable for the application of this document.
