This part of IS0 8130 specifies a liquid displacement pyknometer method for the determination of the density of coating powders. The method is based on a determination of the mass and the volume of a test portion. The apparatus specified is relatively inexpensive, but the liquid displacement pyknometer method is liable to give erroneous results, particularly if the powder swells in contact with the displacement liquid used or the displacement liquid does not totally displace the air between the powder particles. The liquid displacement method is much slower in execution and less accurate than the gas comparison pyknometer method specified in IS0 8130-2 and is only to be used if it can be shown that the same results will be obtained as for the gas comparison pyknometer method.
