标准范围

1.1 ISO 2580-1:20 02建立了丙烯腈-丁二烯-苯乙烯（ABS）模塑和挤出材料的名称系统，该系统可用作规范的基础。1.2 ABS塑料的类型通过基于适当级别的指定性能的分类系统彼此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 2580的这一部分适用于所有丙烯腈-丁二烯-苯乙烯材料，该材料由主要基于苯乙烯（和/或烷基取代的苯乙烯）和丙烯腈的共聚物的连续相和主要基于聚丁二烯的分散弹性体相以及其他组分组成，其数量如本文所述。它适用于未改性或经着色剂、添加剂、填料等改性的粉末、颗粒、小球或碎片形式的可正常使用的ABS材料。ISO 2580的这一部分不适用于材料夏比缺口冲击强度小于每平方米3千焦耳；在弹性体相的弹性体中含有小于50质量%的丁二烯；在连续相中含有小于15质量%的丙烯腈。

1.1 ISO 2580-1:2002 establishes a system of designation for acrylonitrile-butadiene-styrene (ABS) moulding and extrusion materials, which may be used as the basis for specifications.1.2 The types of ABS 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 2580 is applicable to all acrylonitrile-butadiene-styrene materials consisting of a continuous phase based mainly on copolymers of styrene (and/or alkyl-substituted styrene) and acrylonitrile and a dispersed elastomeric phase based mainly on polybutadiene, plus other components, in such quantities as specified in the text.It applies to ABS 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 2580 does not apply to materials

• with a Charpy notched impact strength of less than 3 kilojoules per square metre;
• containing less than 50 % by mass of butadiene in the elastomer of the elastomeric phase;
• containing less than 15 % by mass of acrylonitrile in the continuous phase.
