ASTM D4820-99 PDF

Scope: 1.1 These test methods cover the determination of the nitrogen surface area of carbon blacks by the conventional Brunauer, Emmett, and Teller (B.E.T.) theory of multilayer gas adsorption behavior using multipoint determinations. These test methods specify the sample preparation and treatment, instrument calibrations, required accuracy and precision of experimental data, and calculations of the surface area results from the obtained data. 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 responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (The minimum safety equipment should include protective gloves, sturdy eye and face protection, and means to deal with accidental mercury spills.)
