18、odies). 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 a
19、nd nongovernmental, 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. The procedures used to develop this document and those intended for its further maintenance are d
20、escribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

26、rusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given.Procedures and conditions are described for the preparation of test specimens, and procedures for measuring properties of the materials fro
27、m which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize poly(phenylene ether) moulding and extrusion materials are listed.The properties have been selected from the general test methods in ISO 103501. Other test methods in wide use for
28、, or of particular significance to, these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 20557-1.In order to obtain reproducible and comparable test results, it is intended to use the methods of preparation and conditioning, th
29、e specimen dimensions and the test procedures specified in this document. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.2 Normative referencesThe following documents are referred to in the text in
