Sensibilit\u00e9 m\u00e9canique (friction) : ONU s\u00e9rie 3, \u00e9preuve 3 (b) (i) : \u00c9preuve de frottement BAM<\/h1>\n

Pour cette \u00e9preuve, des substances solides ou p\u00e2teuses sont soumises au frottement entre des surfaces standardis\u00e9es dans des conditions d\u00e9finies de sollicitation et de mouvement relatif.<\/h2>\n

L\u2019appareil \u00e0 frottement se compose d\u2019une embase (acier coul\u00e9) sur laquelle est mont\u00e9 le dispositif de frottement proprement dit. Celui-ci se compose d\u2019un crayon de porcelaine fixe et d\u2019une plaquette mobile en porcelaine. La plaquette en porcelaine est fix\u00e9e sur un chariot coulissant sur deux glissi\u00e8res. Le chariot est entra\u00een\u00e9 par un moteur \u00e9lectrique par l\u2019interm\u00e9diaire d\u2019une biellette, d\u2019une came \u00e0 excentrique et d\u2019un jeu d\u2019engrenages, de telle mani\u00e8re que la plaquette ex\u00e9cute sous le crayon un seul mouvement de va-et-vient sur une course de 10 mm. La force exerc\u00e9e sur le crayon de porcelaine peut \u00eatre par ex. de 120 ou 360 N.
\nLes plaquettes de porcelaine plates sont en porcelaine technique blanche pure (rugosit\u00e9 9 \u03bcm \u00e0 32 \u03bcm) et sont de dimensions 25 mm (longueur) \u00d7 25 mm (largeur) \u00d7 5 mm (hauteur). Le crayon cylindrique de porcelaine est \u00e9galement porcelaine technique blanche pure. Il a une longueur de 15 mm, un diam\u00e8tre de 10 mm et une surface d\u2019extr\u00e9mit\u00e9 sph\u00e9rique rugueuse pr\u00e9sentant un rayon de courbure de 10 mm.<\/p>\n

On consid\u00e8re que le r\u00e9sultat d\u2019\u00e9preuve est positif si, avec l\u2019appareil \u00e0 frottement d\u00e9crit, une explosion se produit au moins une fois dans un essai. Un cr\u00e9pitement et\/ou un bruit de d\u00e9tonation ou une inflammation sont consid\u00e9r\u00e9s comme une explosion. Un changement de couleur n\u2019est pas consid\u00e9r\u00e9 comme une explosion.[\/vc_column_text][vc_row_inner rt_row_style=\u00a0\u00bbglobal-style\u00a0\u00bb rt_bg_custom_alignment=\u00a0\u00bbtop\u00a0\u00bb class=\u00a0\u00bbtest__illustration–desktop\u00a0\u00bb][vc_column_inner width=\u00a0\u00bb1\/2″ rt_column_shadow=\u00a0\u00bb\u00a0\u00bb rt_bg_image_repeat=\u00a0\u00bbrepeat\u00a0\u00bb rt_bg_size=\u00a0\u00bbauto auto\u00a0\u00bb rt_bg_attachment=\u00a0\u00bbscroll\u00a0\u00bb][vc_single_image image=\u00a0\u00bb10943″ img_size=\u00a0\u00bbfull\u00a0\u00bb add_caption=\u00a0\u00bbyes\u00a0\u00bb][vc_single_image image=\u00a0\u00bb10946″ img_size=\u00a0\u00bbfull\u00a0\u00bb add_caption=\u00a0\u00bbyes\u00a0\u00bb][vc_column_text]1)\u00a0\u00a0\u00a0 Embase en acier<\/p>\n
