Thermocouple Locations

There is no information in GDP guideline as to location of or how many thermo couplings for temperature measurement should be inserted into the load space during the qualification test. Therefore, the locations of the thermo couplings are referred to as in the ATP guideline. ATP is using standard NFX 15-140. This means 15 thermocouples per zone are utilised in the box during the multi-temperature’s qualification test and 25 thermocouples for the single temperature qualification test. These loggers are calibrated, and the calibration documents are available under request.
