Full Description
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 59 |
1.3 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 The values stated in SI units are to be regarded as the standard.
1.5 This standard does not purport to address all of the safety concerns, 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.
