This test should also be done at 500 deg F, not 480.

J-STD-003   4.2.3.4.1 After fluxing and draining per  . . . slide the coupon
gently on molten solder. Allow coupon to float on solder for 5 seconds
maximum. The coupon may be depressed into the solder bath to a maximum of
50% of the coupon thickness after it has been initially floated on the
solder. After the elapsed time, slide the coupon off molten solder. Hold
coupon still and horizontal until solder solidifies.
