ASTM D287 - API gravity of crude petroleum and petroleum products.
It covers the determination using a glass hydrometer of the API gravity of crude petroleum and petroleum products usually handled as liquids. It has a Reid vapour pressure (Test Method D323) of 26 psi (180 kPa) or less.
ASTM D1298 - Density, relative density (specific gravity), or API gravity of crude petroleum and petroleum products by hydrometer.
This covers the laboratory determination, using a glass hydrometer, of the density, relative density (specific gravity), or API gravity of crude petroleum, petroleum products, or mixtures of oil and non-petroleum products usually handled as liquids and having a Reid vapour pressure of 14.696 psi (101.325 kPa) or less.
