22、 of properties 1 Scope This part of ISO 4613 specifies the methods of prep- aration of test specimens and the test methods to be used in determining the properties of E/VAC moulding and extrusion materials. Requirements for handling test material and for conditioning both the test ma- terial before

23、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 characteri

24、ze E/VAC moulding 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 4613, as are the design

25、atory proper- ties specified in part 1. In Order to obtain reproducible and comparable test results, it is necessary to use the methods of prep- aration and conditioning, the specimen dimensions and the test procedures specified herein Values de- termined will not necessarily be identical to those o

26、btained using specimens of different dimensions or prepared using different procedures. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 4613.
