Scope

This Part of GB/T 2546 specifies the methods of preparation of test specimens and the
test methods to be used in determining the properties of polypropylene (PP) 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.
This Part also specifies the methods and conditions for specimen preparation and
properties determination. This Part lists the properties and test methods which are
suitable and necessary to characterize PP 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 Part, as well as include determination of
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.
