scope:

Establishes a system of designation for Methyl methacrylate-acrylonitrile-butadiene-styrene (MABS) thermoplastic materials, which may be used as the basis for specifications. The types of MABS plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties Vicat softening temperature, melt flow rate, impact strength, flexural modulus and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. Is applicable to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.
