--- Increase the specific method for determining the moisture content of the sample (3.2), so that the standard implementation is more instructive.

This standard was proposed by the China Petroleum and Chemical Industry Federation.

This part is under the jurisdiction of the National Plastics Standardization Technical Committee (SAC/TC15).

This standard is mainly drafted by. Zhonglan Chenguang Chemical Research and Design Institute Co., Ltd., Zhejiang Xinhecheng Special Materials Co., Ltd., Dunhuang West

1 Scope

This part of GB/T 37194 specifies the sample preparation and performance test methods for polyphenylene sulfide molded and extruded materials, as well as the sample site.

Requirements for conditioning of the sample before and after molding of the sample.

At the same time, this part specifies the procedures and conditions for sample preparation, as well as the performance test procedures for samples prepared from materials.

Suitable properties and test methods suitable for polyphenylene sulfide molding and extrusion materials.

The performance item is selected from the general test method GB/T 19467.1. Other widely used or extruded materials of polyphenylene sulfide molding and extrusion materials

Other important test methods are also included in this section, such as melt mass flow rate or melt viscosity, density and elongation in ISO 28078-2

Modulus.

In order to obtain repeatable and comparable test results, it is necessary to specify the method of sample preparation and condition adjustment as well as sample size and measurement.

Try the steps. Test data obtained from samples of different sizes or different preparation processes are not necessarily identical.
