This part of IEC TS 62607 provides a method for the determination of magnetic impurities in anode nanomaterials for energy storage devices using an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES), including test overview, reagents, apparatus, test procedures, test results and test report.

This document applies to the determination of the total content of magnetic impurities (iron, cobalt, chromium, and nickel) ≥ 0,02 mg/kg which can be attracted by magnet.
