Standard test method for determining density of structural lightweight concrete

This test method provides procedures to determine the oven-dry and equilibrium densities of structural lightweight concrete. 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 non-conformance with the standard. Some values have only SI units because the inch-pound equivalents are not used in practice.
