1. Scope
1.1 This test method covers the determination of the total
surface area by the Brunauer, Emmett, and Teller (B.E.T. NSA)
theory of multilayer gas adsorption behavior using multipoint
determinations and the external surface area based on the
statistical thickness surface area method.
1.2 The values stated in SI units are to be regarded as the
standard. The values given in parentheses are for information
only.
1.3 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
