1.1 This test method is applied to the measurement of the mechanical properties of powders as a function of normal stress.

1.2 This apparatus is suitable measuring the properties of powders and other bulk solids, up to a particle size of 5000 micron.

1.3 This method comprises four different test procedures for the determination of powder mechanical properties.

Test A-Measurement of INTERNAL FRICTION as a function of normal stress.Test B-Measurement of WALL FRICTION as a function of normal stress.Test C-Measurement of BULK DENSITY as a function of normal stress and time.Test D-Measurement of DEGRADATION as a function of normal stress.

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.
