ISO International Standard

ISO 19066-1:2014 establishes a system of designation for methyl methacrylate-acrylonitrile-butadiene-styrene (MABS) moulding and extrusion materials, which can be used as the basis for specifications. The types of MABS plastic are differentiated from each other by a classification system based on appropriate levels of the designatory properties

a) Vicat softening temperature,

b) melt volume-flow rate,

c) Charpy notched impact strength, and

d) tensile modulus,

and on information about composition, intended application and/or method of processing, important properties, additives, colorants, fillers, and reinforcing materials.
