A detailed study has been made by the Electrical Hazards Panel of the Committee on Hazardous Materials to determine the feasibility of classifying some 200 chemicals of commerce according to the classifications given in the National Electric Code, NEC 500, by using a scheme based entirely on available physical and flammability properties only. The system would eliminate the present laborious process of actually testing the piece of electrical equipment in the vapors of the particular chemical of concern.
