ASTM D3246 Standard Test Method for Sulfur in Petroleum Gas by Oxidative Microcoulometry
1. Scope
1.1 This test method covers determination of sulfur in the range from 1.5 to 100 mg/kg (ppm by mass) by weight in hydrocarbon products that are gaseous at normal room temperature and pressure.
NOTE 1 - The test method has been tested cooperatively only on high-purity ethylene gas. Precision data have not been developed for other products.
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.
