21、 All irhgts seredevr 1 Plastics Melamine-formaldehyde powder moulding compounds (MF-PMCs) Part 2: Preparation of test specimens and determination of properties 1 Scope This part of ISO 14528 specifies the methods of preparation of test specimens and the test methods to be used in determining the pro
22、perties of powder moulding compounds (PMCs). Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of
23、 the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PMCs are 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 significanc
24、e to, PMCs are also included in this part of ISO 14528, as are the designatory properties found in ISO 14528-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified h
25、erein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of thi

44、orque M B measured in accordance with ISO 15062 may be taken as a measure 4 Preparation of test specimens 4.1 General It is essential that specimens are always prepared by the same procedure (either injection moulding or compression moulding), using the same processing conditions. The procedure to b
45、e used for each test method is indicated in Tables 3 and 4 (M = injection moulding, Q = compression moulding). 4) To be published.

46、e content of filled or reinforced materials shall be expressed as a percentage of the total mass of the compound. 4.2 Pretreatment of the material Before processing by injection moulding, no treatment of the sample is normally necessary. If pretreatment is required, this shall be in accordance with
47、the manufacturers recommendations. Before processing by compression moulding, treatment of the sample in accordance with ISO 295:, subclause 5.2 (preforming), 6.2 (drying), 6.3 (high-frequency preheating) or 6.4 (preplastification), is allowed. 4.3 Injection moulding Injection-moulded specimens shal
