Plastics - Compression moulding of test
specimens of thermoplastic materials
(First revision)
(ISO 293:2004, IDT)
This International Standard specifies the general principles and the procedures to be followed with
thermoplastics in the preparation of compression-moulded test specimens, and sheets 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. For each material, the required moulding temperature and cooling methods
are as specified in the appropriate International Standard for the material or as agreed between the interested
parties.
The procedure is not recommended for reinforced thermoplastics.
