Micom Laboratories is delighted to announce that it now offers SAE J2334 test as part of its corrosion testing services . This method describes a cyclic corrosion test which assesses the corrosion performance of a coating system, process, substrate or design. Indeed, this test protocol relies on the use of a salt solution and on the control of the parameters inside the apparatus in order to create a corrosion environment that allows foreseeing the performance of the sample in the field. Hence, this standard is based on the guidelines of ASTM D1735 , ASTM D2247 and SAE J1563.
SAE J2334 test
The goal of the standard SAE J2334 is to describe a cyclic corrosion test that reproduces the natural cyclic behavior. Indeed, the three-stage cycle portrayed on this protocol differentiates itself from a standard salt spray test because there is the introduction of an alternation between dry and wet conditions which models the natural cyclic conditions. By doing so, it creates a corrosive environment that simulates quite well, on an accelerated basis, an outdoor exposure. The corrosion performance is assessed by evaluating the aesthetics of the sample after it had been periodically introduced to the corrosive agent that is composed of: 0.5% of NaCl, 0.1% of CaCl2 and of 0.075% NaHCO3. More specifically, it relies on the cyclical appraising of the corrosion rate and of scribe creepback values in order to gauge the effectiveness of the coating to resist corrosion. Lastly, this method can either serve for validation or development purposes because it is a field correlated test.
Micom offers polymer testing services for a wide selection of material and products. For more information about the SAE J2334, we invite you to contact our material testing laboratory today. It will be our pleasure to answer your questions about either of those tests.

My career has been focused on simulating real life in the lab under controlled yet accelerated conditions. My passion for lab testing lead me to start Micom Laboratories Inc. 16 years ago. Through time I made sure Micom has the necessary equipment to simulate various environmental parameters such as the sun, vibrations, heat, cold, thermal shocks and humidity. I wanted to be able to move things back and forth, apply stresses to the products and materials we test and see how they react to the various stimuli. To do so we test products and materials against known standards and specifications (certification) and in many cases by creating my own test protocols and specifications (this is the cherry on top of the sundae…). This is what led me to participate in many standards writing committees and to become chairman of some of these committees.
