Significance and Use

This test method provides measurements that can be used to describe the bulk properties of a powder or granular material.

The measurements can be combined with practical experience to provide relative rankings of various forms of bulk handling behavior of powders and granular materials for a specific application.

Scope

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

1.2 This 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 7.0 ± 1.0-mm diameter funnel outlet when in an aerated state.

1.3 This method consists of eight measurements and two calculations to provide ten tests for Carr Indices. Each individual test or a combination of several tests can be used to characterize the properties of bulk solids. These ten tests are as follows:

1.3.1 Test A—Measurement of Carr Angle of Repose

1.3.2 Test B—Measurement of Carr Angle of Fall

1.3.3 Test C—Calculation of Carr Angle of Difference

1.3.4 Test D—Measurement of Carr Loose Bulk Density

1.3.5 Test E—Measurement of Carr Packed Bulk Density

1.3.6 Test F—Calculation of Carr Compressibility

1.3.7 Test G—Measurement of Carr Cohesion

1.3.8 Test H—Measurement of Carr Uniformity

1.3.9 Test I—Measurement of Carr Angle of Spatula

1.3.10 Test J—Measurement of Carr Dispersibility

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.
