METHOD FOR NON-DESTRUCTION TESTING OF THERMAL PROPERTIES OF MATERIALS

摘要

measurement of thermal parameters. SUBSTANCE: method comprises steps of placing loop-shaped heater and two temperature sensitive pickups on heat insulated surface of investigated material. At time moment of beginning measurement, heater separates predetermined heat quantity in the form of impulses. Then time moment of achieving predetermined relation of temperature values in points of placing temperature-sensitive pickups is registered. Calculation of thermal characteristics is realized on base of received data according to formulae given in description of invention. EFFECT: enhanced accuracy of testing. 1 dwg _
