This part of ISO15901 describes methods for the evaluation of the volume of micropores (pores of internal width less than 2nm) and the specific surface area of microporous material by low-temperature adsorption of gases[1],[2],[3],[4],[5],[6],[7]. These are comparative, non-destructive tests. The methods use physisorbing gases that can penetrate into the pores under investigation. The method is applicable to isotherms of typeI, II, IV or VI of the IUPAC classification (see ISO15901-2:—, Figure1, and ISO9277).
The methods in this part of ISO15901 are not applicable when chemisorption or absorption takes place.
