ISO DIS 18069

Description / Abstract: This International standard specifies the measurements of the corrosion rate of uniform corrosion for stainless steels and nickel based alloys in the intended aqueous solution and the ability for the material to passivate after activation.

This method is intended to be used for estimation of the uniform corrosion rate for the chemical industry under specific environmental conditions and not as a delivery tests. It can also be used to determine iso-corrosion diagrams and at which temperature the corrosion rate exceeds 0,1 mm/a.

This standard is not intended be used for solutions containing halides, especially chlorides, since these might cause localised corrosion.
