Accelerated Corrosion Tests and the Evaluation of New Automotive Brake Line Coatings

New corrosion resistant coatings for brake tubing have been evaluated by use of the accelerated vehicle corrosion test and the trailer corrosion test. These tests appear useful for comparing the end point perforation resistance of the tubing coating combination and for comparing the corrosion and paint adhesion properties of the coatings, respectively. The paper discusses the procedure and results of the accelerated vehicle corrosion test as well as burst pressure tests after accelerated vehicle corrosion testing.
