RESEARCH AND DEVELOPMENT REPORT ON SPARKING CHARACTERISTICS OF METALS

摘要

Sparking taste were conducted on various metals in explosive mixtures of gasoline and oxygen-enriched air, and ethyl ether and oxygen-enriched air, for the purpose of developing a procedure for evaluating the sparking characteristics of metals. The data obtained were used as a basis for establishing sparking test requirements for nonsparking tools. Recommendations are made to include these requirements in all specifications covering nonsparking tools.
