This European Standard specifies a method to determine the moulding shrinkage of compression moulded test specimens of thermosetting materials. It applies only to materials which exhibit no post-shrinkage after moulding such as polyester SMC and BMC. Knowledge of the shrinkage of these thermosetting materials is necessary for the construction of moulds and for establishing the suitability of the moulding material to produce parts with accurate dimensions.
