BS EN ISO 19062-1:2015建立了丙烯腈-丁二烯-苯乙烯(ABS)的命名体系
模塑和挤压材料,可作为规范的基础。ABS塑料的类型通过基于
指定性能的适当水平:维卡软化温度;熔体质量流动速率;夏比缺口冲击强度;拉伸模量;以及关于成分、预期用途和/或处理方法的信息,非常重要
性能、添加剂、着色剂、填料和增强材料。ISO 19062的本部分适用于所有丙烯腈-丁二烯-苯乙烯材料,包括
主要基于苯乙烯(和/或烷基)共聚物的连续相-
取代苯乙烯)和
丙烯腈和主要基于聚丁二烯的分散弹性体相,以及其他组分,
按正文规定的数量。适用于以粉末、颗粒、颗粒或碎屑形式准备好正常使用的ABS材料,
未经着色剂、添加剂、填料等改性或改性。ISO 19062的本部分不适用于夏比缺口冲击强度小于每平方米3千焦耳、弹性相弹性体中丁二烯质量分数小于50%、连续相中丙烯腈质量分数小于15%的材料。这并不意味着具有相同名称的材料必然具有相同的性能
表演ISO 19062的本部分不提供工程数据、性能数据或
为特定应用指定材料所需的加工条件和/或
处理方法。如果需要此类附加性能,将根据试验方法确定
ISO 2580-2中规定(如适用)。为了指定特定应用的热塑性材料或确保可重复性
数据块5中可能会给出额外的要求。交叉引用:ISO 1043-1ISO 1043-2ISO 2580-2购买时可用的所有现行修订版均包含在本文件的购买中。
BS EN ISO 19062-1:2015 establishes a system of designation for acrylonitrile-butadiene-styrene (ABS)
moulding and extrusion materials, which may be used as the basis for specifications.The types of ABS plastic are differentiated from each other by a classification system based on
appropriate levels of the designatory properties:Vicat softening temperature;melt mass-flow rate;Charpy notched impact strength;tensile modulus;and on information about composition, intended application and/or method of processing, important
properties, additives, colorants, fillers, and reinforcing materials.This part of ISO 19062 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 19062 does not apply to materialswith a Charpy notched impact strength of less than three kilojoules per square metre,containing less than 50 % by mass of butadiene in the elastomer of the elastomeric phase, andcontaining less than 15 % by mass of acrylonitrile in the continuous phase.It is not intended to imply that materials having the same designation give necessarily the same
performance. This part of ISO 19062 does not provide engineering data, performance data, or data on
processing conditions which may be required to specify a material for a particular application and/or
method of processing.If such additional properties are required, they will be determined in accordance with the test methods
specified in ISO 2580-2, if suitable.In order to specify a thermoplastic material for a particular application or to ensure reproducible
processing, additional requirements may be given in data block 5.Cross References:ISO 1043-1ISO 1043-2ISO 2580-2All current amendments available at time of purchase are included with the purchase of this document.
