Description / Abstract:
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.
Purpose
To establish a uniform test method for the wheel and wheel trim
industry when assessing the resistance of components to filiform
corrosion. An objective is to reduce test procedure proliferation
and thereby reduce costs for establishing and maintaining unique
test facilities, test methods, measurement methods, laboratory
accreditations, and operator training. The net effect is to reduce
cost while improving the quality of the test data by adopting
uniform and standardized test methods. The procedure does not
establish performance standards for the components. Performance
standards are to be established by the users of the test and/or
their clients. The method and format for documenting proficiency
is
