22、specimens and determination of properties 1 Scope This part of ISO 14527 specifies the methods 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). Requiremen

23、ts 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 the materials from which these specimens are made are

24、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 significance to, PMCs are also included in this part of ISO 14527,

25、 as are the designatory properties found in ISO 14527-1. 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 herein. Values determined will not necessarily be identi

26、cal 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 this part of ISO 14527.

45、ing a mould cavity, and for which the minimum torque 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

46、 same processing conditions. The procedure to be used for each test method is indicated in Tables 3 and 4 (M = injection moulding, Q = compression moulding). 4) To be published.

47、iners until it is required for use. The moisture 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

48、 is required, this shall be in accordance with 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 Inje
