Test Methods: Hot Oil Test: Spray one c
11、oat of paint over a clean 3 x 8 in (75 x 200 mm) paint panel (0.0004 - 0.0006 in (10 - 15 m) dry film thickness). Air dry 24 h. Place panel in a 600 ml beaker, half filled with M-520 oil. Heat to 65 +/- 3 C for 1 h. Upon removal, the panel shall show no blistering and no more than slight softening o
12、r dulling. Gasoline Test: Spray one coat of paint over a clean 3 x 8 in (75 x 200 mm) paint panel (0.0004 - 0.0006 in (10 15 m) dry film thickness). Air dry 24 h. Place panel in a 600 ml beaker, half filled with Petroleum Naphtha-Aliphatic type at 23 +/- 2 C for 1 h. Upon removal, the panel shall sh
13、ow no blistering and no more than slight softening or dulling. Ethylene Glycol Test: Spray one coat of paint over a clean 3 x 8 in (75 x 200 mm) paint panel (0.0004 - 0.0006 in (10 - 15 m) dry film thickness). Air dry 24 h. Place panel in a 600 ml beaker, half filled with ethylene glycol at 23 +/- 2 C for 1 h. Upon removal, the panel shall show no blistering and no more than slight softening or dulling.
