1. For 8 um to 14 um spectral band thermometers with emissivity set between 0.9 and 1.0 2. The uniformity specification refers to how IR thermometers with different spot sizes both focused at the center of the targer will measure the same temperature. 3. The target has a nominal emissivity of 0.95, however it is radiometrically calibrated to minimize emissivity related uncertainties.
