ISO DIS 20676

Description / Abstract: This International Standard specifies a method for the determination of hydrogen sulfide content in working field natural gas of upstream area by laser absorption spectroscopy. The analytic range is 10×10^-6 to 20% (mol/mol). The analytic range can be expanded to higher content with special requirement to the instrument.

The use of this international standard can involve hazardous material, operations and equipments. This international standard does not aim to address all of the safety problems associated with its use. It is the responsibility of the user of this international standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
