标准范围
This part of ISO 19064 establishes a system of designation for styrene/acrylonitrile (SAN) mouldingand extrusion materials, which may be used as the basis for specifications.The types of styrene/acrylonitrile plastic are differentiated from each other by a classification systembased on appropriate levels of the designatory properties,a) Vicat softening temperature,b) melt mass-flow rate,and on information about composition, intended application and/or method of processing, importantproperties, additives, colorants, fillers and reinforcing materials.This part of ISO 19064 is applicable to all copolymers of styrene and/or substituted styrene havingbetween 5 % (m/m) and 50 % (m/m) acrylonitrile.It applies to materials ready for normal use, unmodified or modified by colorants, additives, fillers, etc.This part of ISO 19064 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 19064 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 shall be determined in accordance with the test methodsspecified in ISO 4894-2, 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).
