20、 2011 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies(ISO member bodies). The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in
21、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 with ISO, also take part in the work. ISO collaborates closely with theInternational Electrotechnical Commission
22、(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 International Standards. Draft International Standardsadopted by the technical commi
23、ttees 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. In other circumstances, particularly when there is an urgent market requirement for such documents, atechnical committee may decide to
24、 publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the membersof the parent committee casting a vote; an ISO Tec
25、hnical Specification (ISO/TS) represents an agreement between the members of a technicalcommittee and is accepted for publication if it is approved by 2/3 of the members of the committee castinga vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed
26、 for afurther three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS isconfirmed, it is reviewed again after a further three years, at which time it must either be transformed into anInternational Standard or be withdrawn. Attention is drawn to the possibili
27、ty that some of the elements of this document may be the subject of patentrights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 22391-7 was prepared by the European Committee for Standardization (CEN) Technical CommitteeTC 155, Plastics piping systems and du
28、cting systems, in collaboration with ISO Technical CommitteeISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipesand fittings for water supplies, in accordance with the Agreement on technical cooperation between ISO andCEN (Vienna Agreement).
