1.1 These test methods cover the chemical analysis of graphite. 1.2 The analytical procedures appear in the following order: Sections Silicon by the Molybdenum Blue (Colorimetric) Test Method 8 to 14 Iron by the o-Phenanthroline (Colorimetric) Test Method 15 to 21 Calcium by the Permanganate (Colorimetric) Test Method 22 to 28 Aluminum by the 2-Quinizarin Sulfonic Acid Test Method 29 to 35 Titanium by the Peroxide (Colorimetric) Test Method 36 to 43 Vanadium by the 3,3'-Dimethylnaphthidine (Colorimetric) Test Method 44 to 51 Boron by the Curcumin-Oxalic Acid (Colorimetric) Test Method 52 to 591.3 The preferred concentration of sought element in the final solution, the limits of sensitivity, and the precision of the results are given in Table 1. 1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See 56.1 for specific caution statement. |
