Hi, About Lugano test I have heard an interesting argument about the emissivity controversy.
Someone said simply that what the IR cam measure is the IR radiation, and that whatever is the emissivity from the IR cam result you have an estimate of the radiated heat... then the error in emissivity cause only an error in temperature, which cause an error on convection... I am quite skeptical on that argument, as - the IR energy measured is only done in a given bandwidth 74.5-13um, and depending on the temperature the energy received may not be proportional to the whole energy radiated - maybe the IR cam don't measure the energy, but the photon count, or the slope of energy (the color), and this hypothesis is false... however even if probably it is wrong, it may be approximatively true, and error in emissivity may cause a second order error in emitted power, not something as big as the emissivity error itself.
