Plastics — Compression moulding test specimens of thermoplastic materials

Specifies the general principles and the procedures to be followed with thermoplastics in the preparation of specimens, which are homogeneous and isotropic and from which test specimens may be machined or stamped. In order to obtain mouldings in a reproducible state, the main steps of the procedure, including four different cooling methods, are standardized. Two alternative kinds of moulds, flash moulds and positive moulds, are specified.
