ISO 6402-2:20 03规定了试样的制备方法和用于测定丙烯腈-苯乙烯-丙烯酸酯(ASA)、丙烯腈-(乙烯-丙烯-二烯)-苯乙烯(AEPDS)和丙烯腈-(氯化聚乙烯)-苯乙烯(ACS)模塑和挤出材料的性能的测试方法。给出了处理试验材料以及在成型前对试验材料和试验前对试样进行调节的要求。 给出了制备试样的程序和条件以及测量制造这些试样的材料的性能的程序。列出了表征ASA、AEPDS和ACS模塑和挤出材料的合适和必要的性能和测试方法。 这些特性选自ISO 10350中的通用测试方法。广泛使用或对这些模塑和挤出材料特别重要的其他测试方法也包括在ISO 6402的这一部分中，如第1部分中规定的指定特性。

ISO 6402-2:2003 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of acrylonitrile-styrene-acrylate (ASA), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) and acrylonitrile-(chlorinated polyethylene)-styrene (ACS) 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 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 ASA, AEPDS and ACS 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, or of particular significance to these moulding and extrusion materials, are also included in this part of ISO 6402, as are the designatory properties specified in Part 1.
