CONTAINED IN VOL. 15.01, 2018 Defines the performance of virgin, newly impregnated or in-service, granular or palletised activated carbon for the removal of hydrogen sulphide from an air stream.

1.1This test method is intended to evaluate the performance of virgin, newly impregnated or in-service, granular or pelletized activated carbon for the removal of hydrogen sulfide from an air stream, under the laboratory test conditions described herein. A humidified air stream containing 1 % (by volume) hydrogen sulfide is passed through a carbon bed until 50 ppm breakthrough of H₂S is observed. The H₂S adsorption capacity of the carbon per unit volume at 99.5 % removal efficiency (g H₂S/cm³ carbon) is then calculated. This test is not necessarily applicable to non-carbon adsorptive materials.

1.2This standard as written is applicable only to granular and pelletized activated carbons with mean particle diameters (MPD) less than 2.5 mm. See paragraph 5.3 if activated carbons with larger MPDs are to be tested.

1.3This 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.
