ASTM WK59402

    New Test Methods for Measurement of Hydrogen Sulfide in Workplace Air by Direct-Reading Electrochemical Detectors

    (What is a Work Item?)

    Developed by Subcommittee: D22.04 | Committee D22 | Contact Staff Manager


    1. Scope

    This practice covers the detection of hydrogen sulfide gas in workplace air by direct-reading electrochemical detectors. Aims for protect the workers health and safety when they are working, by monitoring whether the concentration of hydrogen sulfide gas exceeds the maximum allowable concentration (MAC) or other limits. The direct-reading gases detectors using electrochemical sensor are included. The sample results are immediately available by visual observation, thus no follow-up analytical equipment is needed.


    Hydrogen Sulfide; Direct-Reading Electrochemical Detectors


    The current standards are mainly ASTM D4913-2000(2011) "Standard Practice for Determining Concentration of Hydrogen Sulfide by Direct Reading, Length of Stain, Visual Chemical Detectors", etc. However, there is a need for improvement in the uncertainty of the method. Now, the detection method of hydrogen sulfide by electrochemical detector is relatively mature, and it is cheap and widely used. Thus the standard is needed. The government agency, Safety management staff, occupational health technical service organization, or the workers could be the users. They can use this standard directly measuring the hydrogen sulfide concentration in the workplace by using the hydrogen sulfide gas detector based on the electrochemical sensor principle.

    The title and scope are in draft form and are under development within this ASTM Committee.
