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.

Many thanks,
