Resumen:
This part of ISO 8130 specifies a liquid displacement pyknometer method for the determination of the desnity of coating powders. The method is based on a determinaiton 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 erraneous results,particularely 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 ISO 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.
