This SAE Recommended Practice covers a laboratory procedure for testing and evaluating the resistance of surface coatings to chipping by gravel impact. The test is designed to reproduce the effect of gravel striking exposed painted or coated surfaces of an automobile and has been correlated with actual field results. The specific intent of the test is to evaluate organic surface coatings or systems on flat test panels; however, it may be possible to extend this type of testing to finished parts or other types of materials such as anodized aluminum or plated plastics if the results are interpreted with respect to the limitations and intent implied by the original testing procedure and rating system.
The Textile and Flexible Plastics Committee/IFAI is comprised of the Automotive Materials Association, whose members are recognized as industry leaders committed to the growth of the automotive industry. The activities of the association center on: ¿ the development and harmonization of standards and test methods ¿ cooperation with international standards organizations ¿ education and promotion of standards, test methods and new technologies Participants in the SAE Textile and Flexible Plastics Committee/IFAI include OEMs, suppliers, consulting firms, government and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
