Plastic powdered melamine - formaldehyde molding compounds (MF-PMCs) Part 2. Sample preparation and determination of properties

1 Scope

GB/T 13454 in the provisions of this section for powdered melamine - Preparation of formaldehyde molding compound (MF-PMCs) performance test specimens Processes and test methods.

This section specifies the method of test material to be treated and the state of the molding material samples to be tested before the pre-test and adjustment requirements.

This section applies to melamine-formaldehyde powder molding compounds (MF-PMCs) and sample preparation procedures and conditions for use of these samples test material Performance with method also applies to characterize the performance of their testing methods MF-PMCs required.

Performance Project selected generic test method GB/T 19467.1-2004. Some other particularly important or broad MF-PMCs make Test methods are also included in this part of GB/T 13454, the characteristic performance can be GB/T 13454.1 found in.

In order to obtain comparable and have a reproducible test results should be in accordance with the process of sample preparation and status adjustment method provided herein, specimens Dimensions and test methods. Using different sample size or sample preparation method of test data may not be consistent.
