FIELD: measurement technology. SUBSTANCE: process refers to means for determination of water VAPOR permeability of such materials as genuine leather, film and textile materials, material with polymer coats and others with respect to vapors of water. In agreement with process change in time of surface conductance of thin layer of powdery substance exhibiting drying properties is registered and by its change quantity of penetrated vapors is estimated. EFFECT: improved authenticity of method, expanded application field. |
