4.4.1 Corrosion resistance test. Five test specimens prepared in accordance with 4.2.2 shall be used for corrosion resistance testing. After the coating application, the test specimens shall be dried at 60 to 100 ºF (16 to 38 ºC) for 24 hours (see 6.14). The test specimens shall then be subjected to a 5 percent salt spray test in accordance with ASTM-B117 for 168 hours, except that the significant surface shall be inclined 6 ± 2 degrees from the vertical. After exposure, test pieces shall be cleaned in running water not warmer than 100 ºF (38 ºC), blown with clean, dry unheated air, and visually examined for conformance to 3.6.1. The dry unheated air for type I shall be not warmer than 100 ºF (38 ºC) and for type II shall follow the manufacturer’s recommended temperature ranges.
