Test Method for Catalytic Carbon Brake Disk Oxidation
The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This test is designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions.
Rationale: The SAE G-12 committee requested that AIR5567A be converted to an AS format to detail the test procedure to evaluate alkali metal Runway Deicer Fluids (RDF’s) for catalytic oxidation of carbon brakes. Also a pass/fail criteria was requested to be added to interpret the test results
