DIN EN ISO 20557-2:2018 塑料 聚苯醚(PPE)成型和挤出材料 第2部分:试样的制备和性能测定(ISO 20557-2:2018);德文版 EN ISO 20557-2:2018
Plastics - Poly(phenylene ether) (PPE) moulding and extrusion materials - Part 2: Preparation of test specimen and determination of properties (ISO 20557-2:2018); German version EN ISO 20557-2:2018
This part of the standard specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of poly(phenylene ether) 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 here. 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 ether) moulding and extrusion materials are listed.
