des \u00e9l\u00e9ments de fixation en titane est la barre, et la d\u00e9finition de la barre est dimensionnelle plut\u00f4t que descriptive. ASTM B348 distingue la barre de la billette par la surface de section, en fixant la limite \u00e0 16 pouces carr\u00e9s, 10323 millim\u00e8tres carr\u00e9s, et limite en outre la barre rectangulaire \u00e0 une largeur ne d\u00e9passant pas 254 millim\u00e8tres avec une \u00e9paisseur sup\u00e9rieure \u00e0 4.8 millim\u00e8tres (ASTM B348, d\u00e9finitions de barre et de billette). Les diam\u00e8tres des \u00e9l\u00e9ments de fixation sont tr\u00e8s inf\u00e9rieurs \u00e0 cette limite, c'est pourquoi la question de classification dans une demande d'\u00e9l\u00e9ments de fixation concerne la pi\u00e8ce finie plut\u00f4t que le mat\u00e9riau \u00e0 partir duquel elle est usin\u00e9e.<\/p>\n<p>Les limites de composition chimique figurant sur un certificat d'\u00e9l\u00e9ment de fixation sont des limites d'analyse de coul\u00e9e relev\u00e9es lors de la fusion. Pour Grade 2, la limite d'oxyg\u00e8ne est de 0.25 pour cent maximum avec le fer \u00e0 0.30 pour cent maximum, et pour Grade 5, la plage d'aluminium est de 5.5 \u00e0 6.75 pour cent avec le vanadium \u00e0 3.5 \u00e0 4.5 pour cent (ASTM B348, exigences chimiques). Ces valeurs sont produites selon des m\u00e9thodes d\u00e9sign\u00e9es plut\u00f4t que selon une pratique g\u00e9n\u00e9rale : ASTM B348 r\u00e9f\u00e9rence ASTM E1409 pour l'oxyg\u00e8ne et l'azote, ASTM E1447 pour l'hydrog\u00e8ne et ASTM E1941 pour le carbone, avec arrondi selon ASTM E29 avant comparaison de toute valeur \u00e0 une limite (ASTM B348, documents r\u00e9f\u00e9renc\u00e9s et m\u00e9thodes d'essai). D\u00e9signer une m\u00e9thode \u00e9tablit comment une valeur a \u00e9t\u00e9 produite. Cela n'ajoute pas un examen que la commande n'a pas demand\u00e9.
