标准范围

ISO 15901-3:2007描述了通过低温气体吸附评估微孔体积（内部宽度小于2 nm的孔）和微孔材料比表面积的方法。这些是比较性的无损检测。这些方法使用物理吸附气体，这些气体可以渗透到被调查的孔隙中。该方法适用于IUPAC分类的I、II、IV或VI型等温线（见ISO 15901-2:-、图1和ISO 9277）。当发生化学吸附或吸收时，ISO 15901-3:2007中的方法不适用。

ISO 15901-3:2007 describes methods for the evaluation of the volume of micropores (pores of internal width less than 2 nm) and the specific surface area of microporous material by low-temperature adsorption of gases 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 type I, II, IV or VI of the IUPAC classification (see ISO 15901-2:--, Figure 1, and ISO 9277).The methods in ISO 15901-3:2007 are not applicable when chemisorption or absorption takes place.
