Filiform Corrosion Test Procedure for Painted Aluminum Wheels and Painted Aluminum Wheel Trim
This test procedure defines a laboratory procedure for generating and evaluating filiform corrosion on painted aluminum wheels and painted aluminum wheel trim. While this test was developed specifically for the testing of painted aluminum wheels and wheel trim it may be applicable to other components. The application owner will need to assess if this test generates filiform similar to that found in the relevant usage to ensure it will provide accurate data for the application.
Rationale: This document is being updated to add additional information on procedures to measure the samples using image analysis. A sub-group of the task group is working to update the procedure to ensure the capability to measure the length, area and frequency of filiform can be completed using image analysis to industry standards. The proficiency process and documents will be updated to account for these changes.
