10. Corrosion Testing in the 21st Century

Speaker:
Brian Smith, Assured Testing

Corrosion protection requirements for coated parts are becoming increasingly more demanding.  Only 15 short years ago the standard corrosion test was ASTM B117 Neutral Salt Fog, and the typical requirement for zinc electroplated parts ranged from 48 to 96 hrs, and for coated parts 240 to 480 hrs in B117 was the norm.  Now, nearly one decade into the 21st century, finishes are expected to achieve as much as 1500 hrs of Salt Fog, or 40, 60, even 80 cycles of one of a number of cyclic accelerated corrosion tests, with alphanumeric designations such as SAE J2334, GM9540P, GMW14872, VDA 621-415 and others.  This presentation explains what coating applicators need to know about the current state of corrosion testing and what it means for applicators and their customers.
