2015-11-06
ISO 19062-1:2015建立了丙烯腈-丁二烯-苯乙烯(ABS)模塑和挤出材料的命名体系,可作为规范的基础。
ABS塑料的类型通过基于适当等级的指定性能的分类系统相互区分:
a) 维卡软化温度;
b) 熔体质量流动速率;
c) 夏比缺口冲击强度;
d) 拉伸模量;
以及有关成分、预期用途和/或加工方法、重要性能、添加剂、着色剂、填料和增强材料的信息。
ISO 19062-1:2015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/或烷基取代苯乙烯)和丙烯腈共聚物的连续相和主要基于聚丁二烯的分散弹性相,以及文本中规定数量的其他组分。
适用于未经着色剂、添加剂、填料等改性或改性的、以粉末、颗粒、颗粒或碎片形式准备正常使用的ABS材料。
ISO 19062-1:2015不适用于材料
a) 夏比缺口冲击强度低于每平方米3千焦耳,
b) 所述弹性体相的弹性体中丁二烯的质量分数低于50%,以及
c) 连续相中丙烯腈质量分数低于15%。
这并不意味着具有相同名称的材料必然具有相同的性能。ISO 19062的本部分不提供工程数据、性能数据或加工条件数据,这些数据可能需要用于指定特定应用和/或加工方法的材料。
如果需要此类附加性能,则应根据ISO 2580?2规定的试验方法(如适用)进行测定。
为了为特定应用指定热塑性材料或确保可重复加工,数据块5中可能会给出额外要求(见3)。

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:
a) Vicat softening temperature;
b) melt mass-flow rate;
c) Charpy notched impact strength;
d) tensile modulus;
and on information about composition, intended application and/or method of processing, important properties, additives, colorants, fillers, and reinforcing materials.
ISO 19062-1:2015 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.
ISO 19062-1:2015 does not apply to materials
a) with a Charpy notched impact strength of less than three kilojoules per square metre,
b) containing less than 50 % by mass of butadiene in the elastomer of the elastomeric phase, and
c) containing 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 (see 3.1).
