It really depends on the purpose of the test. Is this reliability or packaging test?
From my experience with testing medical device packaging, profiles may vary slightly from test to test. However, you probably want to stress outter packaging for three environmental extremes before proceeding with distribution simulation testing: (cold, dry and wet)
Example of environmental conditioning profile for MDP:
-18 C (uncontrolled RH) @ 24hr
38 C (85% RH) @ 24hr
60 C (30% RH) @24hr
