The work of preparing International Standards is normal
22、ly carried out through ISO technical committees. Each member body interested in a subject 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
23、 work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare I
24、nternational Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some o
25、f the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11298-3 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids. ISO 11298 consists of the
26、 following parts, under the general title Plastics piping systems for renovation of underground water supply networks: Part 1: General Part 3: Lining with close-fit pipes Lining with continuous pipes is to form the subject of a part 2; lining with cured-in-place pipes is to form the subject of a par
27、t 4; lining with adhesive-backed hoses is to form the subject of a part 6. BS EN ISO 11298-3:2011ISO 11298-3:2010(E) ISO 2010 All rights reserved vIntroduction This part of ISO 11298 is a part of a System Standard for plastics piping systems of various materials used for the renovation of existing p
28、ipelines 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 piping systems for renovation of underground water supply networks; Plastics pip
29、ing 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 conventionally installed plastics piping systems by the requirement to verify ce
30、rtain 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: General and all applicable renovation technique family-related parts from the f
31、ollowing: 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 family are given in part 1, applied in conjunction with the relevant other part. F
32、or 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 every area of application and this is reflected in the part numbers included in each
33、 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 clause structure and the relationship between ISO 11298 and the System Standards

35、nd water supply networks Part 3: Lining with close-fit pipes 1 Scope This part of ISO 11298, in 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
36、 consumption, including raw water intake pipelines. It is applicable to polyethylene (PE) pipe 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
