ASTM D7356/D7356M-13 + Redline

1.1 This test method covers an accelerated exposure test intended to simulate defects in automotive clearcoats caused by acid rain² that occur at the Jacksonville, Florida exposure site. Exterior exposures at an acid rain test location in Jacksonville, Florida produce etch defects that range from small pits to 12.7 mm [0.5 in.] in diameter or larger acid-etched spots. The latter type of defect is not produced in other acid-etch tests that only produce pits that are smaller than 6.35 mm [0.25 in.] in diameter.³
