Method for the certification of heater blankets by means of infrared thermography

摘要

Method for the certification of heater blankets by means of infrared thermography, in which a heater blanket (1) to be certified is enclosed in a vacuum bag (3,4,5,5',8,9,10) arranged above a support (2) and thermally insulated therefrom, the vacuum is formed inside said bag and said heater blanket is connected until its temperature is stabilized at a predefined value, considerably higher than the ambient temperature, whereupon the best infrared image or images of said heater blanket (1) are recorded and stored by means of an infrared camera (14) situated opposite it, then interrupting the electric power supply to said heater blanket and processing the stored images so as to produce, finally, a certification report.
