- Scope
- 1.1 This standard specifies the test methods for the density, relative density and API specific gravity of petroleum fractions and viscous oils that are homogeneous liquids at the test temperature. 1.2 This standard is applicable to liquid samples with a vapor pressure lower than 100 kPa and a kinematic viscosity not greater than 15 000 mm2/s at the test temperature. For the case where the vapor pressure is greater than 100 kPa, if it is determined that there are no air bubbles in the U-shaped oscillating tube (the existence of air bubbles will affect the test results), the test can also be carried out. Products to which this standard applies include, but are not limited to: gasoline, diesel, jet fuel, base oils, waxes and lubricating oils, etc. 1.3 The precision discussed in this standard is obtained at 15 °C, and the wax is solid at 15 °C, so the precision discussed in this standard is not applicable to the wax density test results. For the detection of wax, the instrument should be equipped with a high temperature control device to ensure that the sample is in a liquid state when it is injected into the sample tube. When using high temperature control devices, the instrument manufacturer should be consulted for appropriate operating and safety instructions. 1.4 This standard is not applicable to dark liquid samples whose existence of air bubbles cannot be determined. 1.5 This standard adopts the International System of Units, except for special instructions. 1.6 This standard does not elaborate on all safety matters. If there is an indication in the standard, please follow it. Before using this standard, users should establish appropriate safety and protection measures and develop corresponding systems.
