What is ISO 3838 - Determination of the density or relative density of crude petroleum and of petroleum products about?
ISO 3838 specifies methods for the determination of the density or relative density of crude petroleum and of petroleum products handled as liquids.
The capillary-stoppered pyknometer method is also for use with solids and this method may also be used for coal tar products, including road tars, creosote and tar pitches, or for mixtures of these with petroleum products.
The graduated bicapillary pyknometer method is recommended for the accurate determination of the density or relative density of all except the more viscous products and is particularly useful when only small amounts of samples are available. The method is restricted to liquids having Reid vapor pressures of 130 kPa or less according to ISO 3007 and having kinematic viscosities less than 50 mm2/s [50 centistokes (cSt)] at the test temperature.
Special precautions are specified for the determination of the density or relative density of highly volatile liquids.
Note: This method is not suitable for the determination of the density or relative density of highly volatile liquids having Reid vapour pressures greater than 50 kPa according to ISO 3007 or having an initial boiling point below 40 °C.
Who is ISO 3838 - Determination of the density or relative density of crude petroleum and of petroleum products for?
ISO 3838 on determination of the density or relative density of crude petroleum and of petroleum products is useful for:
- Petroleum products
- Testing laboratories
- Manufacturers of the pumping system
Why should you use ISO 3838 - Determination of the density or relative density of crude petroleum and of petroleum products?
Density is a very important characteristic in relation to the functioning of petroleum products and the performance of machines. Petroleum products of specific density are required for pumping a system. Therefore it is important to determine the density of such products to ensure the efficiency of systems.
ISO 3838 helps you determine the density or relative density of crude petroleum and of petroleum products using capillary-stoppered pyknometer and graduated bicapillary pyknometer methods with precision and accuracy.
