ASTM E423 - 71(2002) Standard Test Method for Normal Spectral Emittance at Elevated Temperatures of Nonconducting Specimens

Developed by Subcommittee: E21.04 |Book of Standards Volume: 15.03

"1. Scope

1.1 This test method describes an accurate technique for measuring the normal spectral emittance of electrically nonconducting materials in the temperature range from 1000 to 1800 K, and at wavelengths from 1 to 35 m (microns?). It is particularly suitable for measuring the normal spectral emittance of materials such as ceramic oxides, which have relatively low thermal conductivity and are translucent to appreciable depths (several millimetres) below the surface, but which become essentially opaque at thicknesses of 10 mm or less..."

"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 procedures required to determine the normal and hemispherical
emittance of said object.

This test method includes calibration instructions for the spectrometer and procedures
for selecting reflectance-reference standards."...
