13、dards bodies (ISO member bodies). 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 org
14、anizations, governmental and non-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. International Standards are drafted in accordance with the rules given
15、 in the ISO/IEC Directives, Part 3. 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
16、 that some of the elements of this part of ISO 14531 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

21、at the properties of PE-X, in particular its high fracture resistance and its socket and saddle fusion-jointing capability, render it suitable for use in high-performance gas-distribution systems. The philosophy of ISO 14531 is to provide the platform for the introduction of PE-X gas pipe systems by
22、 embracing a performance envelope beyond that covered by existing PE standards, whilst taking its application into regimes of higher operating pressure and extremes of operating temperature. ISO 14531-1 is therefore one part of a four-part system standard covering pipes, fittings for heat-fusion joi
23、nting, fittings for mechanical jointing and design and installation guidelines. The content is suitable for use by procurement authorities and distribution engineers responsible for the design, installation and operation of pipeline systems.
