The UK participation in its preparation was entrusted to Technical Committee PRI/42, Fibre reinforced thermosetting plastics and prepregs, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the
6、 interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn
7、to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Cat

14、rnational Organization 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
15、 been established has 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 s
16、tandardization. International 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
17、 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 14527 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 14527-2 was prep
18、ared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 12,Thermosetting materials. After a transition period of, at the most, four years, the three parts of ISO 14527 (see below), together with the three parts of ISO 14528, will replace ISO 2112:1990, of which they constitute a technical re

22、ods of preparation of test specimens and the test methods to be used in determining the properties of urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs). Requirements for handling test material and for conditioning both the test material before moulding a
23、nd 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 and test methods which are suitable and necessary to characterize PMCs ar
24、e 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 14527, as are the designatory properties found in ISO 14527-1. In order to obtain reproducible an
25、d 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 obtained using specimens of different dimensions or prepared using different p
26、rocedures. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 14527. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to a
