6.1.5. Emissivity...
Emissivity
The emissivity describes the capability of a body to emit
electromagnetic radiation. This is material-specific and must be
adapted for correct measurement results.
Non-metals (paper, ceramic, gypsum, wood, paints and coatings),
plastics and food have high emissivity, which means that the
surface temperature can be easily measured using infrared.
