Abstract
Overview
EN 27520:1991 specifies a standardized method for the determination of cobalt content in ferronickel using flame atomic absorption spectrometry (AAS), based on . This method applies to cobalt concentrations ranging from 0.025% to 2.5% by mass. It provides a detailed procedure including reagents, apparatus, sampling, sample preparation, and calculation of results. EN 27520:1991 facilitates precise and reproducible chemical analysis critical for quality control in nickel alloy production.
