FIELD: measurement equipment.
SUBSTANCE: method includes measurement of average values of temperature and heat flow on external and internal surfaces for several intervals of time, serial variation of value and initial values of time intervals, fixation of those time intervals and measured average values of temperature and heat flow, in which these values differ by value that does not exceed value of previously specified error, and detection of controlled section heat transfer resistance and detection of thermal resistance along the whole surface of investigated object.
EFFECT: improved validity of control of thermotechnical characteristics of investigated object and in expansion of method field of application.
