Corrosion Resistance Testing

Corrosion resistance testing assesses the impact of corrosive atmospheres on components, coatings, etc. In corrosion testing materials and components are exposed to corrosive atmospheres to assess the impact of on material performance and/or appearance. Test conditions in standard tests are designed to accelerate corrosion that may occur in service environments.

Capability – At TTL, we test materials, components and coatings for a variety of customers from aerospace, automotive, truck OEMs as well as mining, metals, and coating manufacturing markets. We have several environmental cabinets to run salt spray, salt fog, acidified salt spray, etc., on small test coupons to full sized components like truck wheels, auto wheels, etc.

Some relevant standards:

  • ASTM A961 – Standard Specification for Common Requirements for Steel Flanges, Forged Fittings, Valves, and Parts for Piping Applications
  • ASTM B117 – Standard Practice for Operating Salt Spray (Fog) Apparatus
  • ASTM B368 – Standard Test Method for Copper-Accelerated Acetic Acid-Salt Spray (Fog) Testing (CASS Test)
  • ASTM G34 – Standard Test Method for Exfoliation Corrosion Susceptibility in 2XXX and 7XXX Series Aluminum Alloys (EXCO Test)
  • ASTM G67 – Standard Test Method for Determining the Susceptibility to Intergranular Corrosion of 5XXX Series Aluminum Alloys by Mass Loss After Exposure to Nitric Acid (NAMLT Test)
  • ASTM G85 – Standard Practice for Modified Salt Spray (Fog) Testing
  • ASTM G110 – Standard Practice for Evaluating Intergranular Corrosion Resistance of Heat Treatable Aluminum Alloys by Immersion in Sodium Chloride + Hydrogen Peroxide Solution
  • ASTM G112 – Standard Guide for Conducting Exfoliation Corrosion Tests in Aluminum Alloys

Touchstone is committed to providing its customers with quality, reliable test results. That is why we have undertaken the rigorous steps needed to meet and secure the most stringent of test lab accreditations including ISO/IEC 17025, NADCAP 7101 (Materials Test Lab) and NADCAP 7122-I (Non-Metallics Materials Testing).
