DIN ISO 9277
Determination of the specific surface area of solids by gas adsorption - BET method (ISO 9277:2010)

Title (German)

Bestimmung der spezifischen Oberfläche von Festkörpern mittels Gasadsorption - BET-Verfahren (ISO 9277:2010)

Overview

This standard specifies the determination of the overall specific external and internal surface area of disperse or porous solids by measuring the amount of physically adsorbed gas according to the 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 isotherms of type I or to solids which absorb the measuring gas. The committee responsible for this standard is NA 005-11-43 AA "Partikelmesstechnik; Porositäts- und Oberflächenmessverfahren (SpA zu ISO/TC 24/SC 4/WG 3)" ("Particle characterization, porosity and pore size distribution (national mirror committee for ISO/TC 24/SC 4/WG 3")) at DIN.
