    16、 national standards 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. Int

    17、ernational organizations, 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 t

    18、he rules given in the ISO/IEC Directives, Part 2. The main task 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

    19、by at least 75 % of the member bodies casting a vote. Attention 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 21003-5 was prepared by Technical Committee

    22、tem Standard, of which this is Part 5, specifies the requirements for a multilayer piping system. The multilayer piping system is intended to be used for hot and cold water installations inside buildings. In respect of potential adverse effects on the quality of water intended for human consumption,

    23、 caused by the product covered by ISO 21003: This Standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; It should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulati

    24、ons concerning the use and/or the characteristics of this product stay in force. Requirements and test methods for components of the piping systems are specified in ISO 21003-1, ISO 21003-2 and ISO 21003-3 of the ISO 21003-series. CEN ISO/TS 21003-7 gives guidance for the assessment of conformity. T
