This International Standard specifies a method of determining the residual styrene monomer content in reinforced plastics based on unsaturated polyester resins in the polymerized state (hereinafter called UP resins in the polymerized state), by gas chromatography. The residual styrene monomer content is an important criterion in evaluating the degree of cure of UP resins in the polymerized state. This method is not applicable to UP resins of high chemical resistance. This International Standard also specifies a method of determining residual styrene monomer by the Wijs method for laboratories in which gas chromatography is not available.
