9.3 Characteristic emissivity

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

►

Appendix

and

Appendix

. 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)
