scope:

This standard covers a procedure for determining the corrosion resistance of sintered or heat treated MIM grades of stainless steel materials immersed in a 2% sulfuric acid solution.

Immersion of MIM stainless steel in 2% H₂SO₄ solution may result in the gradual dissolution of the metal with time. Corrosion resistance is measured in terms of loss of mass in a specified time. The loss of mass is expressed in g/dm² per day to normalize for the surface area.

The values stated in SI units are to be regarded as the standard.

This standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the potential safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
