DIN EN 196-10:2006-10

This European Standard describes the reference method for the determination of the water-soluble chromium (VI) content of cement. This method consists of two stages, an extraction procedure and an analysis of the filtered extract. Other instrumental procedures may be used for the analysis of the filtered extract provided they are calibrated against the analysis of the filtered extract using the reference procedure. In the case of a dispute, only the reference method is used. This standard describes a method that applies to cements. It may have wider applicability but this should be verified on a product-by-product basis. Guidance in the application of this European Standard to the determination of the water-soluble chromium (VI) content of cement-containing preparations is given in Annex B. The method which had been applied in Germany sof (TRGS 613) is now prt of the standrad in the informative annexure D.
