Methods of test for petroleum and its products. Crude petroleum and petroleum products. Determination of density. Oscillating U-tube method Ingestion-build-54484 BS 7478 covers two areas1 Scope This International Standard specifies a method for the determination, using an oscillating U tube density meter, of the density of crude petroleum and related products within the range 600 kg m3 to 1 100 kg m3 which can be handled as single phase liquids at the test temperature and pressure. This International Standard is applicable to liquids of any vapour pressure as long as suitable precautions are taken to ensure that they remain in single
