Performance　and　Application　of　the　MkⅢE　Ballistic　Mortar（IV） The　MkⅢE　Ballistic　Mortar　Test　Value　for　Organic　Peroxides

Abstract

In　order　to　know　the　explosive　power　of　organic　peroxides，　we　have　conducted　the　MkⅢE　bal－ Iistic　mortar　test　for　them，using　our　standerdized　method． As　the　results，　we　can　obtain　not　only　the　B　values　but　alsoβ’value　for　many　kinds　of　peroxides．In　addition，we　also　can　obtain　some　new finding　on　the　performance　of　the　MkⅢE　ballistic　mortar test，asfollows． （1）　For　such　Iower　expbsive　materials　as　organic　peroxides，　an　amplitude　of　vibration　is　unexpe-ctedly small when an electric detonator is not deeply inserted． （2）As　the　quantity　of　the　material　illcreases，the　amplitude　of　vibration　increases，until　it　reachs toaplateau， （3）When　there　is　no　space　in　the　bottle，the　explosive　power　is　low. （4）　The　BI　values　of　peroxides　are　not　well　correlated　with　the　calculated　heats　of　decomposition．
