We have attempted to apply the revised time-pre~sure test to the mixtures of an inorganic peroxide and a cornbustuble, to evaluate their deflagration hazards. The binary mixtures of an inorganic peroxide and a combustible have their maximurn rates of pressure rise at their composition which has zero oxygen balance as well as other mixtures of an oxidizer and a combustible. Therefore, we have evaluated the deffagration hazards for the mixtures of inorganic peroxides and combustibles at the coiTlposition. As the results, the rates of pressure rise for the, metal peroxides-cellulose mixtures were larger than those of the mixtures which contain a peroxoacid or a perhydrate as an oxidizer, and some of the peroxoacid-cellulose mixtures and the perhydrate cellulose mixtures were not ignited. We also have tried to examine effects of particle size of an oxidizer or a combustible on the rates of pressure rise by deflagration. As the results, the remarkable pressure rise effects were observed for the KCIO,-cellulose mixtures which have high deflagration property, although no remarkable pressure rise effects were observed for the 2 Na.CO*･ 3 H.O.-cellulose mixtures and the 2 Na.C03 '3 H.O.-sorbitol mixtures which have low deffagration property.
