This part of ISO 19063 establishes a system of designation for impact-resistant polystyrene (PS-I)moulding and extrusion materials, which may be used as the basis for specifications.The types of impact-resistant polystyrene plastic are differentiated from each other by a classificationsystem based on appropriate levels of the designatory properties:a) Vicat softening temperature;b) melt mass-flow rate;c) Charpy notched impact strength;d) flexural modulus;and on information about composition, intended application and/or method of processing, importantproperties, additives, colorants, fillers, and reinforcing materials.This part of ISO 19063 is applicable to all impact-resistant polystyrene plastics with a two-phasepolymer system comprised of a continuous phase, consisting of polystyrene and/or a copolymer ofstyrene with an alkyl-substituted styrene, and a dispersed elastomeric phase based on butadiene.It applies to materials ready for normal use, unmodified or modified by colorants, additives, fillers, etc.This part of ISO 19063 does not apply to expandable materials.It is not intended to imply that materials having the same designation give necessarily the sameperformance. This part of ISO 19063 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.If such additional properties are required, they will be determined in accordance with the test methodsspecified in ISO 2897-2, if suitable.In order to specify a thermoplastic material for a particular application or to ensure reproducibleprocessing, additional requirements may be given in data block 5 (see 3.1).
