Plastics — Urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds (UF- and UF/MF-PMCs) — Part 2: Preparation of test specimens and determination of properties

This part of ISO 14527 specifies the methods of preparation of test specimens and the test methods to be used in

determining the properties of urea-formaldehyde and urea/melamine-formaldehyde powder moulding compounds

(UF- and UF/MF-PMCs). Requirements for handling test material and for conditioning both the test material before

moulding and the specimens before testing are given here.

Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the

materials from which these specimens are made are given. Properties and test methods which are suitable and

necessary to characterize PMCs are listed.

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, PMCs are also included in this part of ISO 14527, as are the designatory

properties found in ISO 14527-1.

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
