9、on 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 the right to be represented on that committee
10、. 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. International Standards are drafted in accordance w
11、ith 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 member bodies casting a vote. Attention is drawn
12、 to the possibility that some of the elements of this part of ISO 14528 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14528-1 was prepared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 12,
13、Thermosetting materials. After a transition period of, at the most, four years, the three parts of ISO 14528 (see below), together with the three parts of ISO 14527, will replace ISO 2112:1990, of which they constitute a technical revision.

17、asis for specifications 1Scope 1.1This part of ISO 14528 establishes a data block system for the designation of melamine-formaldehyde powder moulding compounds (MF-PMCs). 1.2The various types of MF-PMC are differentiated from each other by a classification system based on information about the fille
18、r/reinforcement type and content, the intended method of processing, any special properties and those of the special properties used specifically for designation purposes (designatory properties). 1.3This part of ISO 14528 is applicable to all MF-PMCs ready for normal use in the form of powder, gran
19、ules or ground material. 1.4It is not intended to imply that materials having the same designation necessarily give the same performance. This part of ISO 14528 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a part
20、icular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in ISO 14528-2, if suitable. 1.5Whenever general requirement data, as covered by ISO 14528-3, need to be indicated, this is also done usi
21、ng this data block system. 1.6To ensure that code-letters and code-numbers remain unambiguous, and to avoid conflicts within the system, any new code-letters or code-numbers for use in data block 1, 2 or 3 shall be approved before use by the secretariats of ISO/TC 61/SC 1, SC 12 and SC 13. 2Normativ
