Emissivity values shown in the table are only approximate, since several
parameters may affect the emissivity of a material. These include the
following:
1.
Temperature
2.
Angle of measurement
3.
Geometry (plane, concave, convex)
4.
Thickness
5.
Surface quality (polished, rough, oxidized, sandblasted)
6.
Spectral range of measurement
7.
Transmissivity (e.g. thin films plastics)
