This standard - establishes the general principles and lays down the procedure to prepare test specimens of heat- and pressure-moulded thermosetting material from different moulding compounds; --specifies the details for test specimen preparation to be included with the test reports on properties; . gives the general principles for the design of the mould intended for the preparation of the test specimens. The conditions required for preparing, in a reproducible manner, test specimens which will give comparable results are discussed relative to the substance under consideration.
