Description
This Standard specifies a spectrophotometric method for the determination of cobalt in iron and steel.
The method has given satisfactory results on a wide variety of steels containing up to 12% cobalt. However, copper interferes appreciably and the method is limited to a maximum of 10% copper.. The sample is dissolved in acid and nitroso-R-salt added. This forms a red-brown chromosphere which is measured spectrophotometrically at 580 nm.
