This European Standard describes a method for the spectrometric determination of chromium (VI) in chromebearing refractories, before and after use. It is applicable to fired magnesia-chrome products (containingnatural chromite, fused grain or co-clinker) and to unfired materials (with refractory cement or chemical bonds)although it is not to be restricted to these types of refractory. The method is applicable to concentrations up to500 mg/kg of chromium (VI).
