This document specifies the methods for the chemical analysis of cement. This document describes the reference methods and, in certain cases, an alternative method which can be considered to be equivalent. In the case of a dispute, only the reference methods are used. An alternative performance-based method using X-ray fluorescence (XRF) is described for SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5, Mn2O3, SrO, Cl and Br. This method is based on beads of fused sample and analytical validation using certified reference materials, together with performance criteria. A method based on pressed pellets of un-fused sample can be considered as equivalent, providing that the analytical performance satisfies the same criteria. An alternative performance-based method using inductively coupled plasma optical emission spectroscopy (ICP-OES) is described for SO3. When correctly calibrated according to the specified procedures and reference materials, XRF and ICP-OES provides methods equivalent to the reference methods but has not been validated for use yet as a reference procedure for
