Dentistry. Polymerization shrinkage: Method for determination of polymerization shrinkage of polymer-based restorative materials Ingestion-build-260237 rectangular or circular passages1 Scope This International Standard specifies a test method for the measurement of the polymerization shrinkage of external energy activated polymer based restorative materials such as composites and core materials. The method is not suitable for Class 1 (self curing, see ISO 4049) polymer based restorative materials.
