1.1 This guide describes how to measure the pore volume of catalytic materials by water immersion with the excess water removed with a centrifuge. The measured pore volume is converted to the dry pore volume by using the loss on ignition (LOI) of the material. It is generally applicable to both powdered materials and particles greater than about 1 mm.

1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


5.1 This guide provides an alternative way to measure the porosity of catalytic materials without the use of mercury porosimetry. It is useful for research and development as well as quality control purposes. (See Test Methods D4284 and D6761.)
