Test No. 109: Density of Liquids and Solids

Flag for IGO OECD on July 27th 1995
This Test Guideline lists methods for determining the density of liquids and solids, giving only a very succinct description of them. The density of a substance is the quotient of its mass and its volume and is expressed in kg/m3. Several methods are for liquid substance only: hydrometer, immersed body method (both are buoyancy methods) and oscillating densitometer. These methods are applicable to liquids with a dynamic viscosity below 5 Pa s for hydrometer and oscillating densitometer and below 20 Pa s for immersed body method. The method for solids only is the air comparison pycnometer. The volume of a sample of the solid is measured in air or in an inert gas in a calibrated cylinder of variable volume. After concluding the volume measurement, the sample is weighed. The methods for liquids and solids are the hydrostatic balance (a buoyancy method) and the pycnometer. The dynamic viscosity of liquids to be investigated should not exceed 5 Pa s for hydrostatic balance, and should not be above 500 Pa s for ...
