\u00c9preuve pression\/temps (Time-Pressure-Test) : ONU s\u00e9rie 1 \/ s\u00e9rie 2, \u00e9preuve 1 (c) (i) und 2 (c) (i))<\/h1>\n

L\u2019\u00e9preuve pression\/temps sert \u00e0 d\u00e9terminer \u00e0 quelle vitesse du gaz est lib\u00e9r\u00e9 suite \u00e0 l\u2019inflammation d\u2019une substance \u00e0 tester se trouvant sous confinement, et si la pression ainsi engendr\u00e9e peut causer une d\u00e9flagration explosive.<\/h2>\n

L\u2019appareillage d\u2019essai est constitu\u00e9 d\u2019un petit autoclave cylindrique d\u2019une contenance approximative de 17 ml et que l\u2019on remplit de 5 g de substance \u00e0 tester. Le dispositif d\u2019inflammation se trouve \u00e0 l\u2019extr\u00e9mit\u00e9 inf\u00e9rieure du Innenraum, il se compose d\u2019une t\u00eate d\u2019amorce \u00e9lelctrique et d\u2019un morceau de tissu carr\u00e9 de dimension 13 mm x 13 mm \u201eprimed cambric\u00a0\u00bb (toile de lin enduite des deux c\u00f4t\u00e9s d\u2019une composition pyrothechnique de nitrate de potassium\/silicium\/poudre noire sans soufre).<\/p>\n

Pour les essais sur des liquides, le \u00ab\u00a0primed cambric\u00a0\u00bb est entour\u00e9 d\u2019une gaine \u00e9tanche en plastique plastique de telle mani\u00e8re que le \u00ab\u00a0primed cambric\u00a0\u00bb ne soit pas en contact avec la substance liquide.<\/p>\n

La bombe est obtur\u00e9e par un vissage comprenant un disque de rupture en aluminium de 0,2 mm d\u2019\u00e9paisseur, r\u00e9gl\u00e9 pour une pression de rupture d\u2019environ 25 bar. On d\u00e9clenche l\u2019inflammation et la courbe pression\/temps est enregistr\u00e9e. L\u2019essai est \u00e9galement d\u00e9crit comme \u00e9preuve ONU 1 (c) (i) et 2 (c) (i).<\/p>\n

Pour l\u2019\u00e9valuation des r\u00e9sultats, on note le temps n\u00e9cessaire pour que la pression passe de 690 kPa \u00e0 2070 kPa (voir tableau).<\/p>\n\n\n\n\n\n\n
