BS EN 196-2:2013 PDF Download

BS EN 196-2:2013 is a standard that provides the methods for the chemical analysis of cement. The standard outlines both the reference methods and alternative methods that can be considered equivalent. In cases of dispute, only the reference methods are used.

One of the alternative methods described in the standard is the use of X-ray fluorescence (XRF) for the analysis of various elements such as SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5, Mn2O3, SrO, Cl, and Br. This method, when properly calibrated according to specified procedures and reference materials, provides an equivalent analysis to the reference methods. However, it has not been validated for conformity and dispute purposes yet.

The standard also allows for other methods to be used as long as they are calibrated against the reference methods or internationally accepted reference materials to demonstrate their equivalence. The methods described in the standard primarily apply to cements but can also be applied to their constituent materials and other materials that reference these methods.
