scope:
Specifies a method to determine the moulding shrinkage of compression moulded test specimens of thermoset moulding compounds. It applies only to materials which exhibit no post-shrinkage after moulding such as polyester SMC (Sheet moulding compound) and BMC (Bulk moulding compound). Knowledge of the shrinkage allows the construction of moulds to produce parts with accurate dimensions, as well as evaluation of the suitability of a moulding compound of this purpose.
