CONTAINED IN VOL. 05.05, 2015 Defines the determination of the chemisorption of hydrogen at 298 K (25 degrees C) on supported platinum catalysts that have been reduced in flowing hydrogen at 723 K (450 degrees C).

1.1This test method covers the determination of the chemisorption of hydrogen at 298 K (25°C) on supported platinum catalysts that have been reduced in flowing hydrogen at 723 K (450°C). It incorporates a static volumetric vacuum technique at constant volume.

1.2The test method is intended for use on unused supported platinum on alumina catalysts of loadings greater than 0.3 weight %. Data on other supports and lower platinum loadings were not 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.
