AMCP 706-177 (1971) gives the power of PETN as 145% of TNT in the Ballistic Mortar and 173% of TNT in the Trauzl block. It also lists PETN s brisance at 1.5g/cc as 129% of TNT as detd in plate dent test. The Russians use a somewhat different measure of power which they call total efficiency . This involves computing expln product expansion to 1 atm. Andreev Belyaev (Ref 25, p 655) list the total efficiency of 1.6g/cc PETN as 134% of TNT... [Pg.575]

VIII. Explosive Characteristics. Picric Acid is generally considered to be a relatively insensi tive but brisant expl. On a qualitative sensitivity scale of comparing common expls, PA would be judged to be more sensitive than TNT but appreciably less sensitive than Tetryl. Its power and brisance are also similar to those of TNT (112% TNT in the Ballistic Mortar 101% of TNT in the Trauzl Block and 107% in the plate dent test (Ref 48). In this section we will consider the steady detonation parameters. initiation characteristics and potential hazards of PA... [Pg.769]

Plate Denting Tests, although not actually involving shattering by expls, are used as measures of brisance. In these tests the effect of a cylinder of expl when detonated in contact with a steel plate, is detd under such condirioQs that the more powerful expls depress and dent but never puncture or shatter the plate, while leas powerful expls merely dent or bend it...
