Scope

This part of GB/T 3403 specifies the test methods for sample preparation and performance determination of powdered urea-formaldehyde and urea/melamine-formaldehyde molding compounds (UF- and UF/MF-PMCs), and specifies the handling requirements for test materials And the state adjustment requirements of the test material before molding and the sample before testing. This section applies to powdered urea-formaldehyde and urea/melamine-formaldehyde molding compounds (UF- and UF/MF-PMCs) sample preparation steps, conditions and methods for measuring material properties with these samples. It is also applicable to the properties and test methods required for characterizing PMCs. These performance items are selected from the general test methods in GB/T 19467.1-2004. Other widely used or particularly important test methods for PMCs are included in this section, and the characteristic performance is in accordance with the provisions in 4.4.3 and 4.4.4 of GB/T 3403.1-2008. In order to obtain reproducible and comparable test results, the sample preparation method, sample state adjustment method, sample size and test procedure specified in this section should be used. The measured values obtained by using different sample sizes or samples prepared by different methods are not necessarily the same.
