There are several conditions you could apply: 1) 85C, 85%RH 2) 65C, 95%RH 3) 130C, 85%RH, 2 atm HAST But, be careful when applying these test conditions. The failure mechanism must be the same as would be expected in a user environment. There are some published data on acceleration factors, but failure mechanism must be considered there as well.

How can we know the relation/computation of the equivalent year?I only have info regarding the temperature. Andrew J. Medina Quality Control Section QM Department Daeduck Phils., Inc.
