title: [Usage modeling test in aerosols formulations].
abstract: Authors emphasize the importance of "usage-modelling" test concerning the uniformity of doses in the case of aerosol formulations, containing propellants or supplied with atomising devices. Weight measurement was carried out to identify the uniformity of doses per actuation keeping non-use periods in the case of water-based solutions with different density and suspension containing HFC propellants. It can be concluded that uniformity of doses--applying non-use periods during the testing time--significantly depends on the composition, the density of the formulation and the spraying mechanism of the atomising device.
