This test method covers the measurement of apparent density in pounds in air per U.S. gallon at convenient temperatures using a hydrometer, and reporting at any specified atmospheric temperature.
Formerly under the jurisdiction Committee D16 on Aromatic Hydrocarbons and Related Chemicals, this test method was withdrawn in July 2005 and replaced by Test Method D 1298 on Density, Relative Density (Specific Gravity), or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method.

1.1 This test method covers the measurement of apparent density in pounds in air per U.S. gallon at convenient temperatures using a hydrometer, and reporting at any specified atmospheric temperature.
1.2 The following applies to all specified limits in this test method: for purposes of determining conformance with this test method, an observed value or a calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.
1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7 and Note 3.
