Troubleshooting – Causes and Corrective Measures
Definitions
Infrared heat radiation
Infrared heat radiation is electromagnetic radiation emitted
by every body. The amount of radiation depends on the tem-
perature and the emissivity degree of the body.
Emissivity Degree
The emissivity degree of an object depends on the material
and the structure of its surface. It states how much infrared
heat radiation the object emits compared to an ideal heat
emitter (black body, emissivity degree = 1).
