適用范圍：This International Standard specifies a method of determining the moulding shrinkage and the shrinkage after heat treatment of thermosetting moulding materials. These characteristics are useful for the production control of thermosetting materials and for checking uniformity of manufacture. Furthermore, knowledge of the initial shrinkage of thermosetting materials is important for the construction of compression moulds, and that of post-shrinkage for establishing the suitability of the moulding material for the manufacture of moulded pieces with accurate dimensions.
