Crude petroleum and liquid petroleum products. Laboratory determination of density. Hydrometer method algolia-ignore The term Hollow Structural Sections1 Scope This International Standard specifies a method for the laboratory determination, using a glass hydrometer, of the density at 15C of crude petroleum, liquid petroleum products, and mixtures of petroleum and non petroleum products normally handled as liquids and having a Reid vapour pressure (RVP) of 100 kPa or less. This International Standard is suitable for determining the density of mobile transparent liquids. It can also be used for viscous
