4、ate Comments National foreword This British Standard is the English language version of EN ISO 14528-3:1999. It is identical with ISO 14528-3:1999. The UK participation in its preparation was entrusted to Technical Committee PRI/42, Fibre reinforced thermosetting plastics and prepregs, which has the

5、 responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the U

6、K. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding Europ

7、ean publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A Bri

8、tish Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a fro

21、O 9991 All irhgts seredevr 1 Plastics Melamine-formaldehyde powder moulding compounds (MF-PMCs) Part 3: Requirements for selected moulding compounds 1 Scope This part of ISO 14528 specifies the requirements for the physical and chemical properties of melamine- formaldehyde powder moulding compounds

22、(MF-PMCs) and compression- or injection-moulded test specimens produced from them. It is limited 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 importanc

23、e. The properties which are used to characterize the moulding compounds, the test methods and the test conditions are selected from those given in ISO 14528-2. The moulding compounds are divided into types according to their composition and properties. The various types are designated using the desi

24、gnation system defined in ISO 14528-1. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 14528. For dated references, subsequent amendments to, or revisions of, any of these publications do not

However, parties to agreements based on this part of ISO 14528 are encouraged to investigate 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 I

29、ropriate table (Table 1 or 2). Tables 1 and 2 give 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 10 % of the mean value, and individual values of properties 3.1 and 3.2 shall be wit

30、hin 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 between the intereste

31、d 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 be as agreed between t
