ISO/TR 12389:2009 PDF Download

ISO/TR 12389:2009 is a technical report that presents the findings of a test program for the chemical analysis of cement using x-ray fluorescence. The testing program was conducted in multiple laboratories in Japan, Asia, and Europe to evaluate the accuracy and consistency of the analysis method. The samples used in the testing program were Portland cement and a mixture of Portland cement and blast furnace slag.

The report outlines the constituents that were analyzed, including SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Na2O, K2O, TiO2, P2O5, MnO, SrO, and the loss on ignition. Calibration standards and validation materials were used to ensure accurate measurements. The report indicates that ISO/TR 12389:2009 is designed for use in everyday laboratory conditions, allowing for the comparison of performance across different laboratories.
