If the actual shelf life has exceeded 12 months, but less than 2 years, from the bag seal date and the humidity indicator card HIC see Clause 5.

All testing occurs inside the chamber, while the cards are exposed to the test humidity. Special consideration should be given to non-hermetic cavity packages. Floor-life derating is discussed in Clause 7. If bake iedec interrupted for greater than 15 minutes the total time of the interruption should be added to the bake time. C If blank, see adjacent j-td-033b.1 code label 3.
