标准范围

1.1 ISO 6402-1:20 02建立了丙烯腈-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）模塑和挤出材料的名称系统，可用作规格的基础。1.2 ASA、AEPDS和ACS塑料的类型通过基于适当级别的指定性能的分类系统相互区分维卡软化温度熔体体积流量夏比缺口冲击强度拉伸模量以及关于组成、预期应用和/或加工方法、重要性质、添加剂、着色剂、填料和增强材料的信息。1.3 ISO 6402的这一部分适用于所有由主要基于苯乙烯的连续相组成的ASA、AEPDS和ACS材料-丙烯腈(SAN)共聚物(其中苯乙烯组分可以是苯乙烯本身和/或烷基取代的苯乙烯)和主要基于丙烯酸酯(ASA材料)、乙烯-丙烯-二烯(EPDM)(AEPDS材料)，氯化聚乙烯（ACS材料）、有或没有其他成分，数量如文中规定。它适用于ASA、AEPDS和ACS材料，以粉末、颗粒、小球或碎片的形式准备正常使用，未经着色剂、添加剂、填料等改性或改性。ISO 6402的这一部分不适用于材料在连续相中含有小于10质量%的丙烯腈；夏比缺口冲击强度小于每平方米3千焦耳；在ASA的情况下，在弹性体相中含有小于50质量%的丙烯酸酯；在AEPDS的情况下，在弹性体相中含有小于50质量%的乙烯-丙烯-二烯；在ACS的情况下，在弹性体相中含有小于50质量%的氯化聚乙烯。

1.1 ISO 6402-1:2002 establishes a system of designation for acrylonitrile-styrene-acrylate (ASA), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) and acrylonitrile-(chlorinated polyethylene)-styrene (ACS) moulding and extrusion materials, which may be used as the basis for specifications.1.2 The types of ASA, AEPDS and ACS plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties

1. Vicat softening temperature
2. melt volume-flow rate
3. Charpy notched impact strength
4. tensile modulus

and on information about composition, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.1.3 This part of ISO 6402 is applicable to all ASA, AEPDS and ACS materials consisting of a continuous phase based mainly on styrene-acrylonitrile (SAN) copolymer (in which the styrene component may be styrene itself and/or alkyl-substituted styrene) and a dispersed elastomeric phase based mainly onacrylate ( ASA materials),ethylene-propylene-diene (EPDM) (AEPDS materials),chlorinated polyethylene (ACS materials),with or without other components, in such quantities as specified in the text.It applies to ASA, AEPDS and ACS materials ready for normal use in the form of powder, granules, pellets or chips, unmodified or modified by colorants, additives, fillers, etc.This part of ISO 6402 does not apply to materials

• containing less than 10 % by mass of acrylonitrile in the continuous phase;
• with a Charpy notched impact strength of less than 3 kilojoules per square metre;
• containing less than 50 % by mass of acrylate in the elastomeric phase in the case of ASA;
• containing less than 50 % by mass of ethylene-propylene-diene in the elastomeric phase in the case of AEPDS;
• containing less than 50 % by mass of chlorinated polyethylene in the elastomeric phase in the case of ACS.
