Description
Specifies a spectrophotometric method for the determination of cobalt content up to 12 percent in all grades of iron and steel containing less than 10.0 percent copper. The sample is dissolved in acid and nitroso-R-salt added. This forms a red-brown chromophore which is measured spectrophotometrically at 580 nm.
