Scope

This Standard specifies the principle, environmental conditions for
determination, reagents and instruments, test procedures, analysis and
calculation of results, and test report content in determination of magnetic
materials in anode nanomaterials for Li-ion battery in inductively coupled
plasma atomic emission spectrometry (ICP-OES).
This Standard applies the determination of magnetic materials (the sum of
iron, cobalt, chromium, nickel, zinc content) with mass fraction between
0.02×10-6 ~ 20×10-6.
