Q-Lab includes an air preconditioner as a standard accessory with every Q-FOG CRH tester. Not all manufacturers do this, so we often are asked why it is necessary. In short, the Q-FOG CRH air preconditioner ensures reliable, stable, repeatable chambe...

The short answer to this question is no, for two main reasons:There are no international corrosion standards that contain mandatory requirements for the bubble tower water temperature.Bubble tower temperature is not critical to testing, and as a resu...

JASO M609/M610 CCT-I and CCT-II are cyclic corrosion tests that feature a fast transition between conditions. This fast transition requirement is designed to reduce variability between testers and laboratories. The primary difficulty in this test met...

The term “wet bottom” is used in two common standards for corrosion testing - ASTM G85 and SAE J2334. ASTM G85 calls for a few cm of water retained in the bottom of the chamber; SAE J2334 calls for either a reservoir of immersively-heated water or st...

Cyclic corrosion testing is intended to be a more realistic way to perform salt spray tests than traditional, steady state exposures. Because actual atmospheric exposures usually include both wet and dry conditions, it makes sense to pattern accelera...
