The work of preparing
22、 International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison
23、with ISO, also take part in the work. ISO collaborates closely with the InternationalElectrotechnical 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 technica
24、l committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to th

26、 11299 consists of the following parts, under the general title Plastics piping systems for renovation of underground gas supply networks: Part 1: General Part 3: Lining with close-fit pipesISO 11299-3:2011(E)iv ISO 2011 All rights reservedBS EN ISO 11299-3:2013IntroductionThis part of ISO 11299 is
27、part of a system standard for plastics piping systems of various materials used for therenovation of existing pipelines in a specified application area. System standards for renovation deal with thefollowing applications: plastics piping systems for renovation of underground non-pressure drainage an
28、d 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 piping systems for renovation of underground gas supply networks (this application).These sy
29、stem standards are distinguished from those for conventionally installed plastics piping systemsbecause they set requirements for certain characteristics in the as-installed condition, after site processing.This is in addition to verification of characteristics of plastics piping systems as manufact
30、ured.This system standard comprises a Part 1: General and all applicable parts relating to the renovation techniquefamily, from the following: Part 2: Lining with continuous pipes Part 3: Lining with close-fit pipes (this document) Part 4: Lining with cured-in-place pipes Part 6: Lining with adhesiv
31、e-backed hosesThe requirements for any given renovation technique family are specified in this part of ISO 11299 and areapplied in conjunction with the relevant other part. For example, both ISO 11299-1 and this part of ISO 11299specify the requirements relating to lining with close-fit pipes. For c
32、omplementary information, see ISO 11295.Not all technique families are pertinent to every area of application and this is reflected in the part numbersincluded in each system standard.A consistent structure of clause headings has been adopted for all parts of ISO 11299, in order to facilitatedirect
