after a two hour recovery, there shall be no visual difference in hardness and color of the immersed coating when compared to that of the unimmersed portion. The test shall be performed on a draw down of the primer coating on tinplate panels. The dry film thickness shall be 37 + 2 um (0.0015 + .0001 inch). The coating shall air dry for 72 hours prior for testing.

2.4 Quantitative requirements. The coating shall have the following quantitative properties:
