DeFelsko offers a family of Bresle method patches (PosiPatch, Adhesive Patch, Latex Patch) designed to extract soluble salts from steel surfaces per ISO 8502-6/9. These patches facilitate salt contamination testing with the PosiTector SST by forming a sealed test cell for water injection, conductivity measurement, and salt concentration calculation.
The DeFelsko PosiTector SST Series is engineered to accurately measure soluble salt contamination on metal surfaces. Utilizing the Bresle method (ISO 8502-6,9), it provides precise conductivity readings, surface density calculations, and temperature normalization, ensuring reliable results for surface preparation assessments in industrial coatings.
The DeFelsko PosiTest DT Dust Tape Test kit measures both the quantity and particle-size of dust on blast-cleaned steel surfaces in full conformity with ISO 8502-3. Including tape, comparator, illuminated magnifier and reporting forms, it allows pass/fail verification or permanent records in field or lab, all in a rugged carry case.
