21、ISO 14530 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of unsaturated-polyester powder moulding compounds (UP-PMCs). Requirements for handling test material and for conditioning both the test material before moulding and the spe
22、cimens 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 given. Properties and test methods which are suitable and necessary to characterize PMCs are listed.
23、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 14530, as are the designatory properties found in ISO 14530-1. In order to obtain reproducible and comparab
24、le 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 identical to those obtained using specimens of different dimensions or prepared using different procedures.

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
46、of the sample is normally necessary. If pretreatment 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 preheati
