Test de Trauzl BAM : ONU s\u00e9rie F, \u00e9preuve F.3<\/h1>\n

Pour examiner le comportement de d\u00e9tonation, on peut utiliser le test Trauzl BAM (\u00e9preuve ONU F.3) permettant l\u2019exclusion de propri\u00e9t\u00e9s d\u00e9tonantes d\u2019une substance.<\/h2>\n

Pour contr\u00f4ler si une substance ne poss\u00e8de pas de pouvoir d\u00e9tonant, on utilise des blocs de plomb normalis\u00e9s de forme cylindrique d\u2019une hauteur et d\u2019un diam\u00e8tre de 200 mmm, coul\u00e9s \u00e0 partir de plomb doux pur. Ces blocs sont munis d\u2019une cavit\u00e9 axiale de 25 mm de diam\u00e8tre et de 125 mm de profondeur, soit un volume de 61 cm\u00b3. Dans cette cavit\u00e9, on introduit 10 cm\u00b3 de la substance \u00e0 tester (les solides se trouvant dans une feuille d\u2019aluminium et les liquides dans un cylindre en verre \u00e0 paroi mince de fabrication sp\u00e9ciale) et l\u2019on place la substance dans un d\u00e9tonateur normalis\u00e9 avec 0,6 g de nitropenthrite (PETN) comme d\u00e9tonateur initial. On remplit le volume de cavit\u00e9 restant de sable quartzeux, fin et sec (voir figure 1). Le syst\u00e8me ainsi isol\u00e9 est alors amorc\u00e9 par un d\u00e9tonateur (condensateur d\u2019amor\u00e7age) (voir figure 2).<\/p>\n

Une fois le d\u00e9tonateur actionn\u00e9, on vide soigneusement la cavit\u00e9 de tous r\u00e9sidus. On d\u00e9termine alors le volume de dilatation (protub\u00e9rance) de la cavit\u00e9 de 61 cm\u00b3. On calcule ensuite la dilatation du bloc de plomb qui se serait produite pour un \u00e9chantillon de 10 g. Si la dilation obtenue est inf\u00e9rieure \u00e0 10 cm\u00b3 pour 10 g de mati\u00e8re, on peut exclure que la substance poss\u00e8de des propri\u00e9t\u00e9s d\u00e9tonantes. Si la dilatation est \u00e9gale ou sup\u00e9rieure \u00e0 10 cm\u00b3 pour 10 g de mati\u00e8re, il sera n\u00e9cessaire d\u2019examiner le comportement de d\u00e9tonation avec plus de pr\u00e9cision.<\/p>\n\n\n\n\n\n\n
