Characteristic Emissivities

In case none of the methods mentioned above help to determine the emissivity you may use the

emissivity tables ►Appendix A and B. These are average values, only. The actual emissivity of a material

depends on the following factors:

• temperature

• measuring angle

• geometry of the surface

• thickness of the material

• constitution of the surface (polished, oxidized, rough, sandblast)

• spectral range of the measurement

• transmissivity (e.g. with thin films)
