Table B-1 provides guidelines for estimating the emissivity of various
common materials. Actual emissivity, especially of metals, can vary
greatly depending upon surface finish, oxidation, or the presence of
contaminants. Also, emissivity or infrared radiation for some materials
varies with wavelength and temperature. To determine the exact
emissivities for most applications, follow the procedures in Appendix C.
