BS IS0 7391-2 Plastics - Polycarbonate (PC) moulding and extrusion materials - Part 2: Preparation of test specimens and determination of properties
Printed version of this is available at library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This part of IS0 7391 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
here.
Procedures and conditions 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 polycarbonate moulding and extrusion materials are listed.
The properties have been selected from the general test methods in IS0 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 IS0 7391,
as are the designatory properties specified in part 1.
In order to obtain reproducible and comparable test results, it is necessary 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.
