摘要：

FIELD: measurement technology. SUBSTANCE: invention is related to method of nondestructive test of materials with use of harmonic heat source. In accordance with method there are used two unlimitedly extended plates, tested and reference, of specified thickness. Ratio of values of temperatures and phase shift of temperature is recorded in two check points as result of action of harmonic heat source. EFFECT: simplified measurement procedure, increased measurement accuracy. 2 dwg
