Thermocouple Locations

There is no information in the GDP guideline as to the 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 thermocouples are referred to as in standard NFX 15-140. This means 20- 25 thermocouples locations are utilised in the box during the qualification test. These thermocouples are calibrated, and the calibration documents are available under request.
