ASTM D5057-90(2006) PDF

1.1 This test method covers the determination of apparent specific gravity and bulk density in waste. For the purpose of this test method, materials to be measured will be classified into three groups:

1.1.1 Group A - Free-flowing liquids; apparent specific gravity (ASG),

1.1.2 Group B - Granules, powders and water reactive liquids, solids or sludges; bulk density (BD), and

1.1.3 Group C - Bulk solids (such as gravel, paper or wood, etc.); apparent specific gravity (ASG).

1.2 This test method is designed and intended as a preliminary test to complement the more sophisticated quantitative analytical techniques that may be used to determine specific gravity. This test method offers to the user the option and the ability to screen waste for apparent specific gravity or bulk density when the more sophisticated techniques are not available and the total waste composition is unknown.

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.
