Organization: ASTM International
Publication Date: 10 March 1998
Status: inactive
Page Count: 6
ICS Code (Measurement of volume, mass, density, viscosity): 17.060
ICS Code (Chemical reagents): 71.040.30
scope:

1.1 This test method covers the determination of nitrogen adsorption and desorption isotherms of catalysts and catalyst carriers at the boiling point of liquid nitrogen. A static volumetric measuring system is used to obtain about thirty equilibrium adsorption points on each branch of the isotherm, these points being evenly spread over the isotherm.

1.2 This standard does not purport to address all of the safety problems, 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.
