9、n for Standardization) is a worldwide federation of 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
10、 the right to be represented on that committee. International 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. Inter
11、national 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 by at least 75 % of the me
12、mber bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 14529 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14529-2 was prepared by Technical Com
13、mittee ISO/TC 61,Plastics, Subcommittee SC 12,Thermosetting materials. After a transition period of, at the most, four years, the three parts of ISO 14529 (see below) will replace ISO 4896:1990, of which they constitute a technical revision.

17、2: Preparation of test specimens and determination of properties 1Scope This part of ISO 14529 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of melamine/phenolic powder moulding compounds (MP-PMCs). Requirements for handling test
18、 material and for conditioning both the test material before moulding and the specimens before testing are given here. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties an
19、d test methods which are suitable and necessary to characterize PMCs are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, PMCs are also included in this part of ISO 14529, as are the designat
20、ory properties found in ISO 14529-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtaine
21、d using specimens of different dimensions or prepared using different procedures. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 14529. For dated references, subsequent amendments to, or revi
