UNE-EN ISO 25137-2:2017

1.1 This part of ISO 25137 specifies the methods of preparation of test specimens and the test methods tobe used in determining the properties of sulfone polymer moulding and extrusion materials. Requirements forhandling test material and for conditioning both the test material before moulding and the specimens beforetesting are given here.1.2 Procedures and conditions for the preparation of test specimens and procedures for measuringproperties of the materials from which these specimens are made are given. Properties and test methodswhich are suitable and necessary to characterize sulfone polymer moulding and extrusion materials are listed.1.3 The properties have been selected from the general test methods in ISO 10350-1. Other test methodsin wide use for, or of particular significance to, these moulding and extrusion materials are also included in thispart of ISO 25137, as are the designatory properties specified in Part 1.1.4 In order to obtain reproducible and comparable test results, it is necessary to use the methods ofspecimen preparation and conditioning, the specimen dimensions and the test procedures specified herein.Values determined will not necessarily be identical to those obtained using specimens of different dimensionsor prepared using different procedures.
