Would you please share your company's practice regarding 'humidity' mapping
during the OQ/PQ of new or existing chambers. Does your company map
humidity or just temperature?
I would also like to know what the industry standard is regarding:
Type of equipment, probes uses
Number of probes per cubic foot
Placement of probes
Pass/fail criteria?  How much tighter than ICH +/- 5% does the test method
require?
