This document specifies the methods of preparation of test specimens and the test methods to be used in determi ning the properties of styrene-acrylonitrile (SAN) moulding and extrusion materials. It gives the requirements for handling the test material and for conditioning both the test material before moulding and the specimens before testing.
This document gives procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made. It lists properties and test methods which are suitable and necessary to characterize SAN moulding and extrusion materials.
The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 19064-1.
The methods of specimen preparation and conditioning, the specimen dimensions and the test
procedures specified in this document are used in order to obtain reproducible and comparable test
results. Values determined are not always identical to those obtained using specimens of different
dimensions or prepared using different procedures.st edition 2020-03 Plastics — Styrene-acrylonitrile (SAN) moulding and extrusion materials — Part 2: Preparation of test specimens and determination of properties Plastiques — Matériaux à base de styrène-acrylonitrile (SAN) pour moulage et extrusion — Partie 2: Préparation des éprouvettes et détermination des propriétés Reference number ISO 19064-2:2020(E) ？ ISO 2020 ISO 19064-2:2020(E)
