Standard Practice for Screening Apparent Specific Gravity and Bulk Density of Waste
1.1 This standard practice covers the determination of apparent specific gravity and bulk density in a waste sample. For the purpose of this practice, the property to be measured is classified into three groups based on material type:
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 practice is designed and intended as a screening procedure to complement the more sophisticated quantitative analytical techniques that may be used to determine specific gravity. This practice 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 feasibly available and/or the total waste composition is unknown.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
