21、e International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committ
22、ee has been established has the right to be represented on that committee. international organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on ail matters of electrotechn
23、ical standardization. International Standards are drafted in accordance with the rules given 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
24、 by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of IS0 14526 may be the subject of patent rights.

28、d the test methods to be used in determining the properties of phenolic powder moulding compounds (PF-PMCs). Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here. Procedures and conditions for the preparat
29、ion of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PMCs are listed. The properties have been selected from the general test methods in IS0 10350-1.
30、Other test methods in wide use for, or of particular significance to, PMCs are also included in this part of IS0 14526, as are the designatory properties found in IS0 14526-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and condition
31、ing, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedu res. 2 Normative references The following normative documents contain provisions wh
