We've been testing a large steel enclosure in a static airspace to measure the maximum internal temperature and corresponding temperature outside of the enclosure. We want to know the maximum temperature of the outside airspace so that the maxmum inside temperature limit is not exceeded at a 95% confidence level. The maximum internal temperature is measured near the top of the inside of the enclosure, and the outside temperature is determined by averaging the vertical temperature measurements from top to bottom of the enclosure. Using the temperature at the top of the encosure would result in a higher outside temperature rating causing the inside to overheat, using the lowest outside temperature would underate the enclosure.
Using these measurements we want to be able to say that X is the maximum average outside temperature so that the maximum temperature inside of the sealed enclosure, Y does not exceed Z degrees F at a 95% confidence level.
What method should be used to calculate this result?
