One good preliminary source of reference is NEC Article 500.provides a
breakdown of the various classifications of Haz Loc environmentsfrom
there on in, it's a matter of selecting the appropriate product safety
standard to meet the implementation as well as the equipment.
It would be appreciated if someone would provide me with a brief overview of
the testing that is performed in order to classify electronic equipment for
use in a hazardous location where fuel vapors are located.
