Significance and Use | ||
Test Method A is commonly used for quality control testing because of the solvent efficiency of carbon disulfide. Test Method B employs toluene as a solvent because it is less toxic and less volatile than carbon disulfide. Test Method B is more likely to be used for research and development or for any other purpose where such information may be useful. |

1. Scope | ||
1.1 These test methods cover the determination of solvent insoluble materials in a sulfur sample. The two test methods available are: (1) Test Method A, Extraction by Carbon Disulfide, and (2) Test Method B, Extraction by Toluene. If there are no other solvent insoluble materials present in the sulfur, these test methods determine the insoluble sulfur content directly. If other materials are also present, additional testing is necessary to identify what portion of the insolubles is insoluble sulfur. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. For a specific warning, see 5.1. |
