Abstract

Overview

ISO 10697-1:1992 specifies a standardized flame atomic absorption spectrometry (AAS) method for determining the acid‑soluble calcium content in steel. The part covers principle, reagents, apparatus, sampling, test procedure, calibration, analytical performance (precision, detection limits, characteristic concentration) and reporting. The method is applicable to calcium levels from 0.0005 % (m/m) to 0.003 % (m/m) and uses dissolution in hydrochloric and nitric acids followed by AAS measurement of the 422.7 nm Ca line in a dinitrogen‑monoxide/acetylene flame.

Key topics and technical requirements

Scope & definition: Acid‑soluble calcium = calcium dissolved in the specified acids (HCl/HNO3).
Sampling: Follow ISO 377.2 (sampling and preparation of steel samples).
Reagents & solvents: Analytical‑grade reagents and very low‑calcium water (ISO 3696); potassium chloride/lanthanum nitrate buffer; pure iron diluent with
