标准范围
This document specifies the methods of preparation of test specimens and the test methods to be used
in determining the properties of ethylene/vinyl alcohol (EVOH) copolymer moulding and extrusion
materials. It gives requirements for handling test material and for conditioning both the test material
before moulding and the specimens before testing.
This document describes procedures and conditions for the preparation of test specimens, and
procedures for measuring properties of the materials from which these specimens are made. Properties
and test methods which are suitable and necessary to characterize EVOH moulding and extrusion
materials are listed in this document.
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 is the melt mass-flow rate designatory property specified in ISO 21309-1.
In order to obtain reproducible and comparable test results, it is intended to use the methods of
specimen preparation and conditioning, the specimen dimensions and the test procedures specified
herein. Values determined will not necessarily be identical to those obtained using specimens of
different dimensions or prepared using different procedures.
