SAE International Standard Tests Corrosion of Commercial Vehicle Parts

WARRENDALE, Pa., Aug. 13, 2009 - A new SAE International recommended practice addresses the issue of corrosion in commercial vehicle parts.

Recommended practice J2721, “Recommended Corrosion Test Methods for Commercial Vehicle Components,” offers procedures to validate acceptable corrosion performance of metallic parts and assemblies used in medium trucks, heavy trucks, buses and trailers.  Test methods incorporate recurring conditions such as corrosive chemicals, drying, humidity and abrasive exposure, as well as variations in the environment.

“Vehicle corrosion standards available today do not provide suitable coverage for new de-icing chemicals and application methods, nor do they adequately account for aggravating effects such as temperature extremes, abrasion and mechanical stress,” Vern Caron, Chair of the SAE Truck and Bus Corrosion Committee, said.  “This standard was developed to address these issues and also to provide a methodology for evaluating laboratory results and correlating these results with field performance.” 

Recommended practice J2721 was developed by the SAE Truck and Bus Corrosion Committee.
