The method can be used for all types of coating powder, is simple to carry out, but requires more expensive instrumentation than is often used for density determinations. It is based on the determination of the volume of a weighed test portion by measuring the volume of the gas displaced. This is achieved by equalizing the pressure difference which arises due to the displacement of the gas.
