21、ng Compound (SMC) and Bulk Moulding Compound (BMC). 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

23、 of comparable single-point data Part 2 Long-fibre-reinforced plastics. Other test methods in wide use for or of particular significance to these compression and injection moulding materials are also included in this part of EN 14598, as are the designatory properties found in Part 1: Designation an

24、d basis for specifications.In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, test-specimens with the dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtain

25、ed using test-specimens of different dimensions or prepared using different procedures. 2 Normative references The following referenced documents are indispensable for the application of this document.

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

46、tion moulded specimens shall be prepared in accordance with ISO 1268-10 and/or ISO 1268-11, using the conditions specified in Table 1.
