SUBGROUP 1*,2,3,4,5,6 1,2,3,4,5,6 1,2,3 PDA Test Notes The PDA is specified as 5% based on failures from group A, subgroup 1, tests after cooldown as the final electrical test in accordance with method 5004 of MIL-STD-883 Class B. The verified failures of group A, subgroup 1, after burnin divided by the total number of devices submitted for burn-in in that lot shall be used to determine the percent for the lot.
