1.1 This test method covers the single-point determination of the surface area of catalysts and catalyst carriers that exhibit Type II or Type IV nitrogen adsorption isotherms using a nitrogen-helium flowing gas mixture. This test method is applicable for the determination of total surface areas from 0.1 to 300 m 2<\/sup> , where rapid surface area determinations are desired.<\/p>\n

1.2 Because the single-point method uses an approximation of the BET equation, the multipoint BET method (Test Method D 3663 ) is preferred to the single-point method.<\/p>\n

Note<\/span> 1This is particularly true when testing microporous materials.<\/p>\n

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/span><\/p>\n
