Description / Abstract: Purpose.

This standard defines a procedure that was developed for generating and evaluating filiform corrosion on painted aluminum wheels and painted aluminum wheel trim. This test has been used to evaluate the effectiveness of process and material changes with respect to filiform corrosion on aluminum wheels or trim. This procedure has also been used to evaluate filiform corrosion on painted aluminum body panels and parts. Unless otherwise noted, the procedure for testing these parts is identical to that used for testing wheels.

Applicability.

Evaluation of the filiform corrosion resistance of painted aluminum components.
