scope:

This document describes the analytical procedures used to determine the content of C₃A in the clinker starting from a chemical analysis on cement. The method can be applied to CEM type I and IV for the determination of the requirement of C₃A, as defined on EN 197‑1.

This document describes two methods, traditional wet and XRF analysis (EN 196‑2), which can be considered to be equivalent, in the scope of this CEN/TR 17365, for the determination of Al₂O₃, Fe₂O₃ and SO₃.

The same methods are described in EN 196‑2, but for the scope of this document, the X-ray fluorescence (XRF) is the preferred method to be used for the determination of Al₂O₃, Fe₂O₃ and SO₃.
