Salt Spray Testing

Cyclic Corrosion Testing

Kesterernich Testing (Acid Rain Testing)

Salt Spray Testing:

  • DeKalb Metal Finishing's salt spray testing lab meets the ASTM B117, JIS Z 2371, and ISO 9227 specifications.

  • Here's what our customer's can expect via corrosion resistance with our unique passivation & plating process:

      • 240 hours or greater to white rust​

      • 480 hours or greater to red rust

    • Zinc Nickel plating--

      • 360 hours or greater to white rust

      • 1,000+ hours or greater to red rust

    • Zinc Iron plating

      • 168 to 240 hours or greater to white rust

      • 720 hours or greater to red rust

 

Cyclic Corrossion Testing:

  • In today's automotive manufacturing industry, there is continuous pressure to achieve increased corrosion resistance based upon various corrosive atmospheres.

  • DeKalb Metal Finishing is committed to simulating environmental changes within a controlled "yet expedited" setting so to better predict corrosion failure modes after the part has been assembled.

DeKalb Metal Finishing. Cyclic Corrosion
  • .Our Quality Lab is capable of performing Cyclic Corrosion Testing to meet the requirements of GMW14872, SAE J2334 and Ford's CETP L-467 specifications.

Kesternich Testing:

  • This is also known as "Sulfur Dionxide Testing", and it is one of the most strenuous tests in the metal finishing industry.  This is also called, "acid rain simulation" testing.

  • The sulfur dioxide aggressively breaks-down the Zinc plating finish to so determine if the proper thickness has been deposited, as well as to verify the part is resistant to corrosion.

  • DeKalb has partnered with 3rd party accredited laboratories to perform the Kesternich Testing process.

  • Through our partnership with our customer and our 3rd party laboratory we are meeting ISO 3231, DIN 50018, and ASTM G87 specification requirements.
