This test method provides for the measurement of volume of pores that are in the range of catalytic importance and possibly for adsorption processes. This test method requires the use of mercury in order to perform the measurements.

1.1 This test method covers the determination of the total pore volume of catalysts and catalyst carriers, that is, the volume of pores having pore diameter between approximately 14 m and 0.4 nm (4 A).

This test method involves hazardous materials, operations, and equipment. This 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. Specific hazard statements are given in Section . Warning statements are given in 9.1.4, 9.1.7, and 9.1.11.
