scope:

This European Standard describes a performance based method for the chemical analysis of cement for SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5, Mn2O3, SrO, Cl and Brusing x-ray fluorescence (XRF). It may be applied to other relevant elements when adequate calibrations have been established. This European Standard describes an alternative method for analyses of cement for conformity and information purposes based on beads of fused sample and analytical validation using certified reference materials together with performance criteria. A method based on pressed pellets of unfused sample can be considered to be equivalent providing that the analytical performance satisfies the same criteria. Any other methods may be used provided they are calibrated, either against the reference method or against internationally accepted reference materials, in order to demonstrate their equivalence. In the case of dispute, unless otherwise agreed by all parties, only the reference method in EN 196-2 is to be used. This European Standard describes methods which apply principally to cements, but which can also be applied to their constituent materials. They can also be applied to other materials, the standards for which call up these methods. European Standard specifications state which methods are to be used.
