適用范圍：This part of ISO 1622 specifies the methods of prep-aration of test specimens and the test methods to be used in determining the properties of PS moulding and extrusion materials. Requirements for handling test material and for conditioning both the test ma-terial 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 given. Properties and test methods which are suitable and necessary to characterize PS mould-ing and extrusion materials are listed. The properties have been selected from the general test methods in ISO 10350. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this part of ISO 1622, as are the designatory proper-ties specified in part 1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of speci-men preparation and conditioning, the specimen di-mensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimen-sions or prepared using different procedures.
