ASTM E727/E727M-08(2013)

Standard Test Methods for Determining Bulk Density of Granular Carriers and Granular Pesticides

SIGNIFICANCE AND USE
3.1 These test methods were designed principally for clay, corncob, nut shell, paper-based or sand granular carriers, and granular pesticide products, but need not be limited to these materials. There may be more appropriate test methods for other types of granular carriers or pesticide products. The differences in the following test methods are slight, but they offer a choice of a recognized test procedure.
SCOPE
1.1 These test methods are used to determine bulk density of granular carriers and granular pesticides by measuring either free-fall bulk density (Test Method A) or loose-fill bulk density (Test Method B).  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.3 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. For specific hazard statements see Section 4.
