What Is Corrosion?Corrosion BasicsCorrosion is an electrochemical process that returns refined metals to their natural oxide states. The most familiar and widespread example is of iron or steel forming rust. Corrosion leads to billions of dollars in ...

Cyclic corrosion testing provides the best possible laboratory simulation of natural atmospheric corrosion. Research indicates that test results are similar to outdoors in resulting structure, morphology, and relative corrosion rates. Q-FOG cyclic co...

Humidity is a general term that describes the amount of water vapor in the air. Humidity is a critical element of the outdoor environment and contributes to the material degradation in both weathering and corrosion.Humidity can be expressed as either...

Q-Lab's Sean Fowler is one of the organizers for the upcoming Automotive Corrosion Symposium, presented by the Southwest Research Institute (SwRI) and held in Detroit, MI on 31 Mar and 01 Apr. This exciting event brings together industry experts from...

Copper-accelerated Acetic-Acid Salt Spray (CASS) testing is a common quality control corrosion test. This test combines a highly-corrosive, acidic salt solution and a high-temperature fog to accelerate the effects on corrosion-resistant materials lik...

ISO and ASTM are the two major international standards bodies for weathering and corrosion testing. Although they use different terms and organize the documents somewhat differently, they share very similar structures, and most other standards bodies...

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 dew point is the temperature at which dew (condensation) forms and is a measure of atmospheric moisture. It is the temperature to which air must be cooled at constant pressure and water content to reach saturation. Dew points are expressed as a t...

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...
