A thermal coating provider needed to monitor its thermal coating process to make sure the conditions were within process specifications for the material being applied. In particular, the customer needed to record air temperature, surface temperature, relative humidity and dew point. It was critically important to make sure that the surface temperature was at least 5 degrees above the dew point as recommended by ASTM Standard D3276 and ISO Standard 8502-4. It was also important to make sure that the air temperature was within the recommended application range as prescribed by the coatings manufacturer.
