Acid resistance test for metal coated steel

Does anyone know of a acid resistant test method or standard that can be used on metal coated steel ? (Galvalume/ Galvanised etc.)

Please note metal thickness less than 1 mm.

I think I am misunderstanding your question, or you are misunderstanding these coatings. Galvalume and Galvanize are far less acid-resistant than the steel to which they are applied.
