NF EN ISO 12185, T60-172 (03/2024)

This document specifies a method for the determination, by means of an oscillating U-tube density apparatus, of the density of crude oils and related products which are single-phase liquids at the test temperature and pressure in the density range between 600 kg/m3 and 1,100 kg/m3. This document applies to liquids of any vapor pressure, provided that appropriate precautions are taken to ensure that these liquids remain in a single-phase state. The loss of lightweight components leads to changes in density both during sample handling and during density determination. This method is not intended for use with online density devices.
