Requirements for handling test materialand 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 thematerials from which these specimens ar
29、e made are given. Properties and test methods which are suitable andnecessary to characterize PE-UHMW moulding and extrusion materials are listed.The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide usefor or of particular significance to these m
30、oulding and extrusion materials are also included in this part of ISO 11542,as are the designatory properties specified in part 1.In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation andconditioning, the specimen dimensions and the test proce
31、dures specified herein. Values determined will notnecessarily be identical to those obtained using specimens of different dimensions or prepared using differentprocedures.2 Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of
