22、ation for Standardization) is a worldwide federation of national 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
23、 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. I
24、nternational Standards are drafted in accordance with the rules 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 % of the
25、 member bodies casting a vote. Attention is drawn to the possibility 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 14527-3 was prepared by Technical
26、Committee ISOTTC 61, Plastics, Subcommittee SC 12, Thermosetting materials. 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、ed moulding compounds 1 Scope This part of IS0 14527 specifies the requirements for the physical and chemical properties of urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs) and compression- or injection-moulded test specimens produced from them. It is l
30、imited to those powder moulding compounds whose composition and properties are significantly different. It is further limited to those moulding compounds which are of general technical and/or economic importance. The properties which are used to characterize the moulding compounds, the test methods
31、and the test conditions are selected from those given in IS0 14527-2. The moulding compounds are divided into types according to their composition and properties. The various types are designated using the designation system defined in IS0 14527-1. 2 Normative references The following normative docu
32、ments contain provisions which, through reference in this text, constitute provisions of this part of IS0 14527. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IS0 14527 are encouraged to i
33、nvestigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IS0 and IEC maintain registers of currently valid International Standards. IS0 472:1999, Pl

37、 it shall meet the requirements given in Table 1. Table 1 gives the mean value obtained for the set of test specimens used to determine a particular property. Individual values of properties 2.1, 2.2, 2.3 and 2.4 shall be within 1 O % of the mean value, and individual values of properties 3.1 and 3.
38、2 shall be within 5 “C of the mean value. No specific limits are placed on rheological and processing properties. However, suitable rheological and processing properties are essential for the satisfactory use of a moulding compound. The test methods and test conditions used shall be as agreed betwee
39、n the interested parties. In addition, for some applications, it may be useful for information to be made available on other properties, for example: - cure time: - particle size; - moisture content. If this is so, these properties and test methods, as well as the test conditions to be used, shall b
40、e as agreed between the interested parties. 4.2 Filler/reinforcement type and content In order for a phenolic powder moulding compound to be considered as complying with this part of IS0 14527, the nature, form and content by mass of its fillerheinforcement shall be as given in the designation of th
41、e moulding compound (see IS0 14527-1 :1999, subclause 4.2). 2 STD-BSI BS EN IS0 14527-3-ENGL 2000 M 1b24bbq 0823420 213 E Pro- Max. Unit cess- or inga min.
