FIRE HAZARD CLASSIFICATION OF CHEMICAL VAPORS RELATIVE TO EXPLOSION-PROOF ELECTRICAL EQUIPMENT, REPORT III

At the request of the U.S. Coast Guard, a detailed study of flammability has been made by the Electrical Hazards Panel of the Committee on Hazardous Materials in order to assign tentative classifications to 370 chemicals of commerce according to the classification Groups given in the National Electrical Code, NEC 500. The method used was based on available physical and flammability properties, and chemical structure as an adjunct (by homology and analogy) where data were limited. This is a supplementary report to Report II, October 7, 1971, and includes the classification of about 170 additional materials. The first report to the Coast Guard, a study, Fire Hazard Classifiction of Chemical Vapors Relative to Explosion-Proof Electrical Equipment, was issued February 10, 1970.
