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) Test Method	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.
