This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of poly(phenylene sulfide) (PPS) moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given. Procedures and conditions are described 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 poly(phenylene sulfide) 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 use for, or of particular significance to, these moulding and extrusion materials are also included in this document as are the designatory properties specified in ISO 20558?1 (melt mass-flow rate or melt viscosity, density and tensile modulus). In order to obtain reproducible and comparable test results, it is intended to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified in this document. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.
