Requirements for handling test material and for conditioning both of the test material before moulding and of the specimens before testing are found here. Procedures and conditions for the preparation of test specimens and procedures for measuring

22、properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize SMCs and BMCs are listed. The properties have been selected from the general test methods in EN ISO 10350-2, Plastics - Acquisition and presentation

44、onditions. The procedure to be used for each test method is indicated in Table 3 (M = injection moulding, Q = compression moulding). The material shall be kept in styrene-proof packaging until it is required for use. 4.2 Pre-treatment of the material Before processing by injection moulding no pre-tr

45、eatment of the material sample is normally necessary. If a pre-treatment is required this shall be in accordance with the manufacturers recommendations. Before processing by compression moulding pre-treatment of the material sample in accordance with ISO 1268 is allowed. 4.3 Injection moulding Injec
