ISO 11652:1997 PDF

Overview

ISO 11652:1997 specifies a flame atomic absorption spectrometric (AAS) method for the determination of cobalt (Co) content in steel and iron. The method covers cobalt concentrations from 0.003% to 5.0% (m/m) and defines sample preparation, reagents, instrument performance criteria and calibration procedures using a cobalt hollow‑cathode lamp at 240.7 nm. This standard is intended for routine analytical control, certification and quality assurance in metallurgical laboratories.
