CONTAINED IN VOL. 14.02, 2016 Pertains to determine an envelope-specific surface area and its associated average equivalent spherical diameter (from 0.2 to 75 [mu]m) of powders.

1.1These test methods use air permeability to determine an envelope-specific surface area and its associated average equivalent spherical diameter (from 0.2 to 75 µm) of powders. Two test methods are described: One test method for inorganic materials (Test Method 1), and another test method for organic materials (Test Method 2). The values obtained are not intended to be absolute but are generally useful on a relative basis for control purposes.

1.2Units—With the exception of the values for density and the mass used to determine density, for which the use of the gram per cubic centimetre (g/cm³) and gram (g) units is the longstanding industry practice; and the units for pressure, cm H₂O—also long-standing practice; the values in SI units are to be regarded as standard.

1.3This 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.
