Toyota Laboratory Accelerated Cyclic Corrosion Test
This test procedure serves as a general purpose atmospheric corrosion test and can be applied to a wide variety of materials, coatings and interactions of materials.
It has been developed to allow the evaluation of the corrosion resistance of metals used in vehicle bodies where there is a significant influence of chloride ions, mainly as sodium chloride from winter road de-icing salt. This test is cyclic in nature, i.e.; test specimens are exposed to changing climates over time.
Test specimens are placed in an enclosed chamber and exposed to a changing climate.
The test comprises 3 alternative 24 hour single cycles, methods A, B and C.
