ASTM C560-20 Standard Test Methods for Chemical Analysis of Graphite
standard by ASTM International, 05/01/2020
Full Description
1.1These test methods cover the chemical analysis of graphite.
1.2The analytical procedures appear in the following order:
| Sections | |
| Silicon by the Molybdenum Blue (Colorimetric) Test Method | 9 to 15 |
| Iron by the o-Phenanthroline (Colorimetric) Test Method | 16 to 22 |
| Calcium by the Permanganate (Colorimetric) Test Method | 23 to 29 |
| Aluminum by the 2-Quinizarin Sulfonic Acid Test Method | 30 to 36 |
| Titanium by the Peroxide (Colorimetric) Test Method | 37 to 44 |
| Vanadium by the 3,3-Dimethylnaphthidine (Colorimetric) | 45 to 52 |
| Boron by the Curcumin-Oxalic Acid (Colorimetric) Test Method | 53 to 60 |
1.3The preferred concentration of sought element in the final solution, the limits of sensitivity, and the precision of the results are given in Table 1.
1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See 56.1 for specific caution statement.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
