DANSK DS/EN ISO 14663-2 PDF

This part of EN ISO 14663 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of EVOH moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here.
Procedures and conditions are described for the preparation of test specimens, and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize EVOH moulding and extrusion materials are listed.
The properties have been selected from the general test methods in ISO 10350. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this part of ISO 14663, as is the designatory property specified in part 1: melt mass-flow rate.
In order to obtain reproducible and comparable test results, it is necessary 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.
