The work of preparing Internati
14、onal 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 and non-governmental, in liaison with IS
15、O, 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 in the ISO/IEC Directives, Part 3. Draft International Standards
16、 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 that some of the elements of this part of ISO 14526 may be the s
17、ubject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14526-2 was prepared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 12,Thermosetting materials. After a transition period of, at the most, four years, the
18、three parts of ISO 14526 (see below) will replace ISO 800:1992, of which they constitute a technical revision. ISO 14526 consists of the following parts, under the general titlePlastics Phenolic powder moulding compounds (PF-PMCs): ?Part 1: Designation system and basis for specifications ?Part 2: Pr

21、ies the methods of preparation of test specimens and 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 giv
22、en 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 and test methods which are suitable and necessary to characterize PMCs are listed. The properties have been sele
23、cted 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 14526, as are the designatory properties found in ISO 14526-1. In order to obtain reproducible and comparable test results, it is necess
24、ary 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 obtained using specimens of different dimensions or prepared using different procedures. 2Normative references The fo
