1.1 This part of ISO 19065 establishes a system of designation for acrylonitrile-styrene-acrylate (ASA),acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) and acrylonitrile-(chlorinated polyethylene)-styrene (ACS) moulding and extrusion materials, which may be used as the basis for specifications.1.2 The types of ASA, AEPDS and ACS plastic are differentiated from each other by a classificationsystem based on appropriate levels of the designatory properties:a) Vicat softening temperature,b) melt volume-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.1.3 This part of ISO 19065 is applicable to all ASA, AEPDS and ACS materials consisting of a continuousphase based mainly on styrene-acrylonitrile (SAN) copolymer (in which the styrene component may bestyrene itself and/or alkyl-substituted styrene) and a dispersed elastomeric phase based mainly on— acrylate (ASA materials),— ethylene-propylene-diene (EPDM) (AEPDS materials),— chlorinated polyethylene (ACS materials),with or without other components, in such quantities as specified in data block 1.It applies to ASA, AEPDS and ACS materials ready for normal use in the form of powder, granules, pelletsor chips, unmodified or modified by colorants, additives, fillers, etc.This part of ISO 19065 does not apply to materialsa) containing less than 10 % by mass of acrylonitrile in the continuous phase;b) with a Charpy notched impact strength of less than 3 kJ/m2;c) containing less than 50 % by mass of acrylate in the elastomeric phase in the case of ASA;d) containing less than 50 % by mass of ethylene-propylene-diene in the elastomeric phase in the caseof AEPDS;e) containing less than 50 % by mass of chlorinated polyethylene in the elastomeric phase in the caseof ACS.1.4 It is not intended to imply that materials having the same designation give necessarily the sameperformance. This part of ISO 19065 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 are to be determined in accordance with the test methodsspecified in ISO 6402-2, if suitable.1.5 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).
