Abstract: Parameters of deactivation of H₂SO₄ pickling bath, resulting from the presence of iron ions, were determined on the basis of laboratory pickling tests of steel sheets prior to enamelling. The critical value of mass loss of sheet at pickling was determined by means of artificially inoculated pickling solutions increasingly saturated by carbonyl iron and in gradually saturated solution by means of iron from steel sheets. Relationship between the increase of iron amount in pickling solution and the amount of carbonyl iron was determined by mathematical regression analysis.
