METHOD OF ESTIMATION OF FILTERING MATERIALS, PARTS OF FILTERING ELEMENTS AND FILTERING COAGULATING ELEMENTS

摘要

FIELD: test equipment.;SUBSTANCE: method can be used for estimating permeability of filtering materials, air-air-tightness of filtering elements and filtering coagulating elements intended for cleaning gases and liquids (preferably fuels) from pollution. Rosin is used for testing. Rosin is heated till temperature of evaporation and size and number of microscopic particles passing through tested sample during one minute. Period of time within which the number and sizes of particles are determined equals less than 2 minutes.;EFFECT: improved condition of testing; higher environmental parameters; reasonable truth of data.;2 cl
