Coefficient d’utilisation pratique

The tests most used are Ballistic Mortar and Trauzl Block Tests. See also Ballistic Pendulum, Coefficient d utilisation pratique, Cratering Effect, Kraftzahl, Mortar Test and Quinan Test. Cook (1958), pp 36-7 claims... [Pg.306]

Of these tests the "Trauzl Test , also known as "Lead Block Expansion Test is one of the oldest and it became, since 1903, an official test in most of the countries of the world (except GtBritain USA). Accdg to Pe rez Ara (Ref 8, p 113) this test was invented by Beckerhinn in 1877, but accdg to Stettbacher (Ref 6, p 362) an Austrian scientist Trauzl described the method in 1883. In France the test has been used in a modified form known as "coefficient d utilisation pratique (CUP) and is described in Ref 23, pp IX-X XXV-XXVI and in Ref 26... [Pg.476]

The first of these expls, belonging to the type 1 I explosif-couche nitrate, was proposed in 1933 by Burlot Sc Schwo b. Its CUP value (coefficient d utilisation pratique) is 87(PA 100) and gap test value (coefficient dc self-excitation) 6cm [See also C(Explosifs), CSE(Explosifs), Dynamites, Grisou-dynamites, Grisou-dynamites chlorourees, Grisounires, Grisoutines, Grisoutites, N(ExpIosifs), etc]...

Sensitivity to initiation (30 mm diam cartridges)-grams of MF to cause complete deton at density (d), 0. 30g at d 0.85, 0.40 at 1.20, 0.50 at 1.40 and 2.5g at d 1.57 g/cc. In these same cartridges, cast R-Salt at d 1.42 reqd a Brisk a detonator for complete detonation (See also Vol 1, p XXIII) Sensitivity to initiation (by heat) - when 0.02g sample in a lOmm test tube was immersed 10 min in a molten metal bath and heated at 5°/min, melt-ing began at 105°, decompn began at 150°, nitrous gases evolved at 160°, and the sample was entirely decompd at 170°. When the tube was plunged into a bath at 300°, decompn was immediate, at 250° decompn was in 40 sec, at 200° in 2 min, at 150° decompn proceeded very slowly, at 110° some bubbles appeared but no increase in decompn occurred in 20 mins (See also Vol 1, pp XXII - XXIII) Specific work - See Coefficient d utilisation pratique...
