ISO-15158 › Corrosion of metals and alloys - Method of measuring the pitting potential for stainless steels by potentiodynamic control in sodium chloride solution
The following bibliographic material is provided to assist you with your purchasing decision:
ISO 15158:2014 describes the procedure for determining the pitting potential for stainless steels (austenitic, ferritic/austenitic, ferritic, martensitic stainless steel) under potentiodynamic control.
The principal advantage compared with other potentiostatic test methods is the rapidity of this test method, with which the pitting potential can be measured in a single potential scan.
The pitting potential as determined by ISO 15158:2014 can be used as a relative index of performance. For example, one can compare the relative performances for different lots of stainless-steel grades and products. The test described in ISO 15158:2014 is not intended to determine the pitting potential at which actual pitting can occur under real service conditions, or not.
