ASTM D1298 Standard Test Method for Density, Relative Density, or API Gravity of Crude Oil and Liquid Petroleum Products by Hydrometer Method

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D1298 testing. This test method determines the density, relative density, or API gravity of crude oil, petroleum products, or mixtures of petroleum and non-petroleum products normally processed as liquids, using a glass hydrometer in conjunction with a series of calculations, and a Reid of 101.325 kPa (14.696 psi) or less. Vapor pressure values ​​are determined at current temperatures and corrected to 15°C or 60°F through a series of calculations and international standard tables.

The first hydrometer readings obtained are uncorrected hydrometer readings, not density measurements. Readings are measured on a hydrometer at the reference temperature or other suitable temperature and the readings are corrected to the reference temperature via the meniscus effect, thermal glass expansion effect, alternative calibration temperature effects, and oil measurement charts; Values ​​obtained outside the reference temperature are hydrometer readings, not density measurements.

Initial hydrometer readings determined in the laboratory should be recorded before any calculations are made. It includes a procedure for validating or validating equipment for this test method.

Values ​​stated in SI units or inch-pound units should be considered separately as standard. In the text, SI units are shown in parentheses. Values ​​specified in each system may not be exactly equivalent; therefore, each system should be used independently of the other.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
