The work of p
12、reparing International Standards is normally 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,
13、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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main ta
14、sk of technical committees is to prepare International 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. Attenti
15、on is drawn to the possibility that some of 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 7675 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transpo
16、rt of fluids, Subcommittee SC 1, Plastics pipes and fittings for soil, waste and drainage (including land drainage).

21、ope This International Standard specifies the requirements for chlorinated poly(vinyl chloride) (PVC-C) pipes and fittings for soil and waste discharge (low and high temperature) inside buildings, as well as the system itself. It does not include buried pipework. It also specifies the test parameter
22、s for the test methods referred to in this International Standard. This International Standard is applicable to PVC-C pipes and fittings, as well as assemblies of such pipes and fittings, intended to be used for the following purposes: a) soil and waste discharge pipework for the conveyance of domes
23、tic waste waters (low and high temperature); b) ventilation pipework associated with a); c) rainwater pipework inside the building. It is applicable to pipes and fittings designed for jointing by means of elastomeric sealing rings, solvent cementing or integral dual-purpose sockets, i.e. for elastom
24、eric ring seal joints and/or for solvent cement joints. 2 Normative references The following referenced documents are indispensable for the application of this document.
