NFPA 33, Section A.6.2.5
The temperature of the object or material being coated should be maintained at least 28° C (50° F) below the autoignition temperature of the powder.
28° C is 82.4° F
10° C is 50° C
so my question is: Is 28° C or 10° C correct? To be on the safe side I used 28° C.
I believe this part has a typo error 28° C is not 50° F.
