Determination of the specific surface area of solids by gas adsorption using the BET method

95.99 Withdrawal of Standard 20 gush 2010

General information

Current stage: 95.99 Effective date: 20 gush 2010

Originator: ISO

Owner: ISO/TC 24/SC 4

Type: International Standard

ICS: 19.120

Scope

Specifies the determination of the total specific external and internal surface area of disperse or porous solids by measuring the amount of physically adsorbed gas according to the method of Brunauer, Emmett and Teller (BET method). The BET method is applicable only to adsorption isotherms of type II and type IV. The BET method cannot reliably be applied to type I isotherms or to solids which adsorb the measuring gas.
