This part of ISO 19062 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 onappropriate 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, importantproperties, additives, colorants, fillers, and reinforcing materials.This part of ISO 19062 is applicable to all acrylonitrile-butadiene-styrene materials consisting ofa continuous phase based mainly on copolymers of styrene (and/or alkyl-substituted styrene) andacrylonitrile 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 materialsa) 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, andc) 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 sameperformance. This part of ISO 19062 does not provide engineering data, performance data, or data onprocessing conditions which may be required to specify a material for a particular application and/ormethod of processing.
