To meet this need, theAmerican Engineering Standards Committee [later changed to the American Standards Association (ASA)] initiatedProject B31 in March 1926 at the request of The American Society of Mechanical Engineers (ASME), and with thatsociety as sole sponsor. After several years’ work by Sectional Committee B31 and its subcommittees, a firstedition was published in 1935 as an American Tentative Standard Code for Pressure Piping.A revision of the original tentative standard was begun in 1937. Several more years’ effort was given to securinguniformity between sections and to eliminating divergent requirements and discrepancies, as well as to keeping the codeabreast of current developments in welding technique, stress computations, and references to new dimensional andmaterial standards. During this period, a new section was added on refrigeration piping, prepared in cooperation withThe American Society of Refrigeration Engineers (ASRE) and complementing the American Standard Cod

2.1 Flammable liquids Flammable liquids are liquids that will ignite easily and burn rapidly. More precisely, they are liquids with flash points that do not exceed 100 F (37.8 C). Less flammable liquids with flash points at 100 F or higher are categorized as combustible liquids. For storage purposes, flamma
