Description / Abstract:
This part of ISO 20028 specifies the methods of preparation of
test specimens and the standard test methods to be used in
determining the properties of thermoplastic polyester 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.
Procedures and conditions for the preparation of test specimens
in a specified state 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
thermoplastic polyester moulding and extrusion materials are
listed.
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 part of ISO 20028, as are the designatory
properties specified in part 1 (viscosity number and tensile
modulus of elasticity).
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.
