23、tion-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 importance. The properties which are used to

24、 characterize the moulding compounds, the test methods and the test conditions are selected from those given in ISO 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 ISO 14527

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreeme

26、nts based on this part of ISO 14527 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 ISO and IEC maintain registers of cu

30、 this part of ISO 14527, 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 10 % of the mean value, and individual values o

31、f properties 3.1 and 3.2 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 sha

32、ll be as agreed between 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

33、be used, shall be 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 ISO 14527, the nature, form and content by mass of its filler/reinforcement shall be as given in the

34、designation of the moulding compound (see ISO 14527-1:1999, subclause 4.2).
