Many inspectors have to test surfaces in accordance with ISO 8502-6 and ISO/DIS 8502-9, which specify tests using the Bresle Patch as the method of extracting the soluble salts from the test surfaces.
- The Bresle Patch is adhered to the test surface and distilled water is pumped into the patch using a syringe.
- The water is pumped between the patch and the substrate, which causes the soluble salts on the test surface to be dissolved into the water.
