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 polycarbonate 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 in this document.
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 also lists properties
and test methods which are suitable and necessary to characterize polycarbonate 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 21305-1.
In order to obtain reproducible and comparable test results, it is intended to use the methods of
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.
