What Is Emissivity?
The standard of radiation is "blackbody" radiation which exists in any enclosure whose walls
are at a uniform temperature. The shape of the enclosure and the wall material has no effect on
A small hole in such an enclosure only affects this radiation level very slightly. The area of the
hole should not exceed 5% of the area of the walls of the enclosure, when the radiation passing
through the hole is within about one part in a thousand of the blackbody radiation level defined
by the wall temperature. Such a device is fairly easy to build and forms the source on which all
A surface always emits less radiation than would a black body at the same temperature by a
If we ignore the emissivity altogether and infer a temperature from the thermometer output, we
shall get a temperature lower than the true temperature by an amount depending on the value
of emissivity and the characteristics of the thermometer. This temperature is known as the

To obtain the true surface temperature we must divide the actual output by the emissivity value

For materials with smooth, clean (unoxidised) surfaces, emissivities are usually in the range
