Product Code:SAE J2721
Title:Recommended Corrosion Test Methods for Commercial Vehicle Components
Issuing Committee:Truck And Bus Corrosion Committee
Scope:This document establishes recommended practices to validate acceptable corrosion performance of metallic componentsand assemblies used in medium truck, heavy truck, and bus and trailer applications. The focus of the document ismethods of accelerated testing and evaluation of results. A variety of test procedures are provided that are appropriate fortesting components at various locations on the vehicle. The procedures incorporate cyclic conditions including corrosivechemicals, drying, humidity, and abrasive exposure. These procedures are intended to be effective in evaluating a varietyof corrosion mechanisms as listed in Table 2. Test duration may be adjusted to achieve any desired level of exposure.Aggravating conditions such as joint rotation, mechanical stress, and temperature extremes are also considered.This document does not address the chemistry of corrosion or methods of corrosion prevention. For information in theseareas, refer to SAE J447 or similar standard.
