Crude petroleum and liquid or solid petroleum products - Determination of density or relative density - Capillary-stoppered pyknometer and graduated bicapillary pyknometer methods (ISO 3838:2004); German version EN ISO 3838:2004

DIN EN ISO 3838-2004 发布历史

The document specifies methods for the determination of density or relative density of crude petroleum and of petroleum products handled as liquids. The capillary-stoppered pyknometer is for use with solids and coal tar products. It is not suitable for highly volatible liquids having Reid vapour pressure greater than 50 kPA (0,5 bar) according to ISO 3007 or having an initial point below 40 ? The graduated bicappillary pyknometer method is recommended for all except the more viscous products, and is particularly useful when only small amounts of samples are available.
