Applicable to products having a Mn content between 0.0002 % (m/m) and 0.005 % (m/m). Preliminary extraction by the method specified in the annex if the apparatus available does not have a sufficient sensitivity. Describes the dissolution of a test sample by heating in a sealed borosilicate glass tube with hydrochloric acid at a controlled temperature of 250 °C. Aspiration of the solution in an air-acetylene flame and spectrophotometric measurement of the absorption of the 279.5-nm line emitted by a manganese hollow cathode lamp.
