TABLE 6.2
GUIDE TO EMISSIVITY VALUES FOR TARGET MATERIALS IN THEIR “USUAL” FORM
ARRANGED BY CLASSES OF MATERIAL
INSTRUMENT SERIES: MODLINE 4, Series 44 AND 22 SPECTRUM: 8 to 14 microns
All specimens in this table are in their common physical form — e.g. raw materials like coal, gravel, sand, etc. in
their normal granular form; construction products like lumber, paneling, tiles, roofing, etc. in their normal delivered
forms.
Unless otherwise noted, these materials have negligible Transmittance
τ
in their common form. Any difference
between the listed Emissivity
ε
and a “perfect” Emissivity of 1.0 is due to Reflectance
r.
