22、nal 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 committee has been established has the right to be represented on that committee. Internati
23、onal 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 all matters of electrotechnical standardization. International Standards are drafted in accordance with the rul
24、es 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 ?O of the member bodies casting a vote. Attention is drawn to the po
25、ssibility that some of the elements of this part of IS0 14527 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 14527-1 was prepared by Technical Committee ISO/TC 61 , Plastics, Subcommittee SC 12, Thermos

After a transition period of, at the most, four years, the three parts of IS0 14527 (see below), together with the three parts of IS0 14528, will replace IS0 21 12:1990, of which they constitute a technical revision.

29、 powder moulding compounds (UF- and UF/MF-PMCs). This part of IS0 14527 establishes a data block system for the designation of urea-formaldehyde and 1.2 The various types of UF- and UFIMF-PMC are differentiated from each other by a classification system based on information about the filler/reinforc
30、ement type and content, the intended method of processing, any special properties and those of the special properties used specifically for designation purposes (designatory properties). 1.3 granules or ground material. This part of IS0 14527 is applicable to all UF- and UF/MF-PMCs ready for normal
31、use in the form of powder, 1.4 It is not intended to imply that materials having the same designation necessarily give the same performance. This part of IS0 14527 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a p
32、articular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in IS0 14527-2, if suitable. 1.5 using this data block system. Whenever general requirement data, as covered by IS0 14527-3, need to b
33、e indicated, this is also done 1.6 To 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. 2 No
