Scope

This part of GB/T 21650 specifies the method for determining the micropore volume and specific surface area of microporous materials by low temperature gas adsorption. This section applies to IUPAC classification Ⅰ, Ⅱ, Ⅳ or Ⅵ type isotherm (see Figure 1 in GB/T 21650.2-2008 and ISO 9277-1995), this section does not apply to chemical adsorption or absorption.
