TYPICAL EMISSIVITY VALUES

The following tables provide references for estimating emissivity and can be used
when none of the previous three determining steps are practical.  Emissivity values
shown in the tables are only approximate.  Any or all of the following parameters can
affect the emissivity of an object:

1. Temperature

2. Angle of measurement

3. Geometry (plane, concave, convex, etc.)

4. Thickness

5. Surface quality (polished, rough, oxidized, sandblasted) 

6. Spectral region of measurement

7. Transmissivity (i.e., thin film plastics)
