  1. General Details

    ASTM D287 – Api gravity of crude petroleum and petroleum products.

    Covers the determination by means of a glass hydrometer of the API gravity of crude petroleum and petroleum products normally handled as liquids and having 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.

    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 petroleum and non-petroleum products normally handled as liquids, and having a Reid vapour pressure of 14.696 psi (101.325 kPa) or less.
