    Scope - (Show below) - (Hide below)

    1.1This test method covers an apparatus and procedures for measuring properties of bulk solids, henceforth referred to as Carr Indices.2

    1.2This test method is suitable for free flowing and moderately cohesive powders and granular materials up to 2.0 mm in size. Materials must be able to pour through a 6.0 to 8.0-mm diameter funnel outlet when in an aerated state.

    1.3This method consists of eight measurements and two calculations for Carr Indices as follows. Each measurement, or calculation, or combination of them, can be used to characterize the properties of bulk solids.

    1.3.1Measurement of Carr Angle of Repose

    1.3.2Measurement of Carr Angle of Fall

    1.3.3Calculation of Carr Angle of Difference

    1.3.4Measurement of Carr Loose Bulk Density

    1.3.5Measurement of Carr Packed Bulk Density

    1.3.6Calculation of Carr Compressibility

    1.3.7Measurement of Carr Cohesion

    1.3.8Measurement of Carr Uniformity

    1.3.9Measurement of Carr Angle of Spatula

    1.3.10Measurement of Carr Dispersibility

    1.4All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

    1.4.1The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives: and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

    1.5Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.6This 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.
