1.1These test methods cover the determination of total carbon, sulfur, and acid-base characteristics in metal bearing ores and related materials such as leach residues, tailings, and waste rock within the following ranges:
| Analyte | Application Range, % | Quantitative Range, % |
| Total Carbon | 0 to 10 | 0.08 to 10 |
| Total Sulfur | 0 to 8.8 | 0.023 to 8.8 |
Note 1:The test methods were tested over the following ranges: Total Carbon 0.01 % to 5.87 % Total Sulfur 0.0002 % to 4.70 % Residual Carbon from Pyrolysis 0.002 % to 4.97 % Residual Sulfur from Pyrolysis 0.014 % to 1.54 % Pyrolysis Loss Sulfur 0 % to 4.42 % Hydrochloric Acid Insoluble Carbon 0.025 % to 0.47 % Hydrochloric Acid Loss Carbon 0 % to 5.78 % Hydrochloric Acid Insoluble Sulfur 0.012 % to 4.20 % Acid Neutralization Potential Acidity Titration -1.0 % to 100 % Acid Neutralization Potential Acidity Titration Low Range -1.0 % to 2 % CaCO3 Nitric Acid Insoluble Sulfur 0.006 % to 0.924 % Nitric Acid Loss Sulfur -0.08 % to 4.19 % Sodium Carbonate Insoluble Sulfur 0.007 % to 3.78 %
1.2The quantitative ranges for the partial decomposition test methods are dependent on the mineralogy of the samples being tested. The user of these test methods is advised to conduct an interlaboratory study in accordance with Practice E1601 on the test methods selected for use at a particular mining site, in order to establish the quantitative ranges for these test methods on a site-specific basis.
1.3The test methods appear in the following order:
| Sections | |
| Carbon and Sulfur, Total | 10.1 – 10.9 |
| Carbon and Sulfur, Residual from Pyrolysis | 10.10 – 10.18 |
| Carbon and Sulfur, Hydrochloric Acid Insoluble | 10.19 – 10.27 |
| Acid Neutralization Potential Acidity Titration | 10.28 – 10.36 |
| Acid Neutralization Potential Acidity Titration Low Range | 10.37 – 10.46 |
| Sulfur, Nitric Acid Insoluble | 10.47 – 10.55 |
| Sulfur, Sodium Carbonate Insoluble | 10.56 – 10.64 |
1.4The values stated in SI units are to be regarded as 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. Specific warning statements are given in Section 6.
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.
