ASTM D4780-95(2001) Standard Test Method for Determination of Low Surface Area of Catalysts by Multipoint Krypton Adsorption
standard by ASTM International, 08/15/1995
Full Description
1.1 This test method covers the determination of the specific surface area of catalysts and catalyst carriers in the range from 0.05 to 10 m/g. A volumetric measuring system is used to obtain at least three data points which fall within the linear BET region.
1.2 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.
