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.

.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.
