NFRC 301-2004: Standard Test Method for Emittance of Specular Surfaces Using Spectrometric Measurements(Downloadable in PDF Format )
“1 Scope”
“This test method determines the normal and hemispherical emittance of a specular
surface. This test method describes the spectrometric measurement of the near-normal
specular reflectance in the mid-infrared range from mid-infrared 5 to 25 um. It includes
the calculation [...]
