For studies of heat and mass transfer in porous media, operational pulse methods are becoming increasingly common. Unlike most known methods, they eliminate the need for destruction of controlled products for preparing special samples of a given configuration. The metrological analysis of the methods providing the possibility of measuring the diffusion coefficient of polar solvents in block products made of porous materials without their destruction is performed. The areas of their preferred use are justified in the context of ensuring acceptable accuracy, in the presence of pronounced anisotropy of properties including.
