Abstract : This report describes an analytical procedure for the characterization of elastomers used for automotive applications with special emphasis on brake and cooling system components. The procedure involves the thermal degradation of an elastomer sample and subsequent gas-chromatographic analysis of the decomposition products. Positive identification is made by comparing the 'pyrogram' from a sample with those obtained from reference materials. (Author, modified-PL)
