Methods of Validating Equivalence to ISO 8502-9 on Measurement of the Levels of Soluble Salts
The purpose of this standard practice is to define a method that shows equivalence of other methods for measuring the level of contamination of soluble salts on surfaces to the Bresle patch method defined by ISO 8502-9. This standard practice provides a way to establish equivalence by testing and comparing results of the tests to meet established criteria that would be achieved using the method specified in ISO 8502-9. Equivalence is evaluated at three salt levels (30 mg/m2, 50 mg/m2, and 85 mg/m2) on three surface conditions (grit blasted steel, zinc silicate preconstruction primer on steel, and rusted steel).
