Reinforced plastics based on unsaturated-polyester resins. Determination of the residual styrene monomer content, as well as the content of other volatile aromatic hydrocarbons, by gas chromatography Ingestion-build-583201 Scope This International Standard specifies a method for the determination, by gas chromatography, of the residual styrene monomer in reinforced plastics based on unsaturated polyester (UP) resins in the polymerized state. The residual styrene monomer content is an important criterion in evaluating the degree of cure of UP resins in the polymerized state. The method can also be used for the simultaneous determination of other volatile aromatic

resulting in a longer operating lifetime

and it should be possible to map these to proprietary technologies

The main objective of BS 3198 is to provide best industry practices for manufacturing copper hot water storage combination units that are safe and reliable for use

It defines the requirements for the long-term preservation of digital geospatial data

BS EN 62021-3 is a European Standard which is the third part of a multi-series that describes two procedures for the determination of the acidity of unused and used electrical non-mineral insulating oils
