Scope

This document describes the preparation of test specimens and test methods for the
determination of properties of polyketone moulding and extrusion materials. It specifies
requirements for the handling of the test material and/or the conditioning of the test
material before moulding and the test specimens before testing.
The determination method of properties is selected from the general test methods in
GB/T 19467.1. This document also lists other test methods widely used or of special
significance for moulding and extrusion materials, as well as the determination methods
for characteristic properties in GB/T 41758.1.
In order to ensure that the test results are reproducible and repeatable, it is necessary to
use the methods for preparation of test specimens and state conditioning specified in
this document, as well as the specified specimen size and test method. Test data
obtained using specimens prepared under different conditions or using specimens of
different dimensions may not be consistent.
