1.1 This test method covers the determination of total carbon and sulfur in metal bearing ores and related materials such as 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 %.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 %

1.2 The 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 E 1601 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.

1.3 The test methods appear in the following order:

	Sections
Carbon and Sulfur, Total
Carbon and Sulfur, Residual from Pyrolysis
Carbon and Sulfur, Hydrochloric Acid Insoluble
Sulfur, Nitric Acid Insoluble
Sulfur, Sodium Carbonate Insoluble

1.4 The values stated in SI units are to be regarded as standard.

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. Specific warning statements are given in Section 7.
