Scott volumeter method

Comments This method could obviously be applied to other than just metallic powders but the necessary pre-requisite is that the powder is still reasonably free-flowing so that it will pass through the sieve and cascade down the baffle box into the cup. If light brushing is not sufficient to get the powder through the sieve, the Scott volumeter method cannot be used. The density measured is the bulk density of the material as poured under the specified conditions, and this will probably be lower than other bulk densities like the tap density.

A Scott volumeter is suggested as being suitable for measuring the density of metal powders." The method gives a bulk density of the metal powder and results can be related to the measurement of tamped volume (see below). The Scott volumeter is more complex and precise than the ISO method. The result is given as apparent density.
