scope:

1.1 This guide is intended to direct interested investigators to existing ASTM Test Methods that may be useful for determination of surface area of advanced ceramic materials.

1.2 This guide is not intended to endorse any particular test method or methods; nor does it intend to include all existing test methods that may be applicable. It shall be the option of the investigator to judge whether or not one or more of the listed test methods is appropriate for use with the materials of interest.

1.3 All numerical values shall be stated in terms of SI units and shall be considered as standard unless specific instrumentation software reports surface area using alternate units. In this case, both reported and equivalent SI units shall be presented in the final written report. Many instruments report surface area as square metres per gram, instead of using the correct SI units square metre per kilogram.

1.4 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.
