21、ional 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. Interna
22、tional 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 r
23、ules given in the ISOAEC 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/O of the member bodies casting a vote. Attention is drawn to the
24、possibility that some of the elements of this part of IS0 15252 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights.

This part of IS0 15252 establishes a data block system for the designation of epoxy powder moulding 1
27、.2 The various types of EP-PMC are differentiated from each other by a classification system based on information about the filler/reinforcement type and content, the intended method of processing, any special properties and those of the special properties used specifically for designation purposes
28、(designatory properties). 1.3 ground material. This part of IS0 15252 is applicable to all EP-PMCs ready for normal use in the form of powder, granules or 1.4 it is not intended to imply that materials having the same designation necessarily give the same performance. This part of IS0 15252 does not
29、 provide engineering data, Performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in par
30、t 2 of this International Standard, if suitable. 1.5 indicated, this is also done using this data block system. Whenever general requirement data, as covered by part 3 of this International Standard, need to be 1.6 To ensure that code-letters and code-numbers remain unambiguous, and to avoid conflic
