Specifies two titrimetric methods for the determination of the copper content of copper sulfide concentrates in the range 15 % (m/m) to 50 % (m/m), titrating free iodine isolated by reaction between iodide ions and copper(II) ions with sodium thiosulfate using soluble starch as the indicator after separation (method 1) or without separation (method 2) of copper from interfering elements.
