Jim, Try National Electrical Code Article 500 Hazardous (Classified) Locations
Class 1 is locations where "flammable gases or vapors are or may be in the air in quantities sufficient to produce explosive or ignitible mixtures" Class 1 Div 1 is as above due to 1) normal conditions, or 2) frequently because of repair operations/leakage/etc, or 3) breakdown/faulty operation Group D is atmospheres such as acetone, ammonia, benzene, butane, cyclopropane, ethanol, gasoline, hexane, methanol, methane, natural gas, naptha, propane, etc If your product carries a rating label with the above Class 1 Div 1 Group D rating and a NRTL mark, you can claim to meet this performance level. If not, I suggest to contact UL in Northbrook IL at 847-272-8800 to discuss evaluating your product. I used to work at Square D Co., which makes HazLoc electrical equipment, and was responsible for building an in-house hydrogen-air testing facility, plus testing with UL witnessing our tests for Listing. My company helps manufacturers get UL and other agency certifications. If we can help, feel free to contact me.
