LSI LASTEM have developed InfoFLUX (BSZ310) in collaboration with the Associazione Nazionale per l’Isolamento Termico ed Acustico (ANIT). It performs the thermal conductance calculation from which the value of transmittance is determined. For every spot measurement, InfoFLUX performs the calculation of thermal conductance by using 2 methods such as black box method and average method.
ISO 9869:1994 describes the "average method" and performs instant to instant conductance calculation without using any actual values of thermal flux, but with the help of the average through previous instant. Then the black box will consider the input data series only and also output data and processing that data with any statistical methods. The main advantage of the black box method is the performance of the shorter measurement is possible than an average method.
The data processing by InfoFLUX will display the average temperature, conductance in each instance of sampling and average flux value. The final value is calculated and highlighted by using all the accessible data. When the value of the conductance is close to a horizontal asymptotes with a 0.05w/m2k maximum amplitude, then there will be considerable oscillation will occur in the convergence system.
