This standard specifies the requirements for portable, stored pressure dry powder fire extinguishers, commonly known as ABC or BC type. It covers materials, construction, performance, testing methods, and marking for extinguishers of various capacities. The standard's goal is to ensure these life-saving devices are reliable and effective against Class A, B, and C fires.
