Scope

This Part of GB/T34691 specifies the methods and conditions for the preparation of test
specimens and the determination of properties of thermoplastic polyester (TP) molding
and extrusion materials. This part also specifies the requirements for the pretreatment
of test materials and the conditioning of test specimens before testing.
This Part lists the appropriate and necessary properties and test methods for
characterizing thermoplastic polyester (TP) molding and extrusion materials. These
properties are selected from the general test methods in GB/T 19467.1-2004. This Part
also lists other test methods that are widely used or have special significance for
molding and extrusion materials.
In order to ensure the reproducibility and repeatability of the test results, the methods
of specimen preparation and state adjustment, as well as the specified specimen size
and test method specified in this part may be used. The test data obtained using
specimens prepared under different conditions or using specimens of different sizes
may be inconsistent.
This standard applies to homopolymer and copolymer thermoplastic polyesters.
