FIELD: biotechnology, test of residual humidity of preparations in medical, microbiological, pharmaceutical and other branches of economy. SUBSTANCE: method includes measurement of residual humidity and of one of physical characteristics of sample of biopreparation by standard methods, construction of calibrated dependence of this physical characteristic of biopreparation on its residual humidity, measurement of physical characteristic of tested sample of this biopreparation and determination of its residual humidity by calibration dependence. Temperature of change of form of sample with heating is used in the capacity of physical characteristic of sample of biopreparation while determining residual humidity. Change of form of sample during heating is controlled visually. EFFECT: enhanced functional authenticity of method. 1 dwg, 1 tbl
