The work of preparing 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 Inon- governmental, 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. 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. International Standard ISO 9623 was prepared by Technical Committee ISO/TC 138, Plastics pipes, fittings and valves for the transport of fluids, Subcommittee SC 2, Plastics pipes and fittings for water supplies. @ISO1997 All rights reserved.

It also specifies the dimensions at the socket and spigot ends of the fitting. The adaptor fittings have one plain socket or spigot for fusion jointing a PE socket or spigot to a PE pipe, or a PP socket or spigot to a PP pipe. The other component of the fitting is metal and is threaded to enable connection to compressionofagasket. NOTE The fittings illustrated in this International Standard have been arbitrarily chosen without prejudice to the designs of adaptor fttings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
