SAE International released a recommended practice that addresses corrosion in commercial vehicle parts, SAE J2721 - Recommended Corrosion Test Methods for Commercial Vehicle Components.
SAE J2721 describes procedures to validate acceptable corrosion performance of metallic parts and assemblies used in medium trucks, heavy trucks, buses and trailers.
Conditions such as corrosive chemicals, drying, humidity, abrasive exposure and environmental variations are addressed in the recommended tests.
"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," said Vern Caron, chair of the SAE Truck and Bus Corrosion Committee.
"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."
