1. Scope |
1.1 This test method covers determination of 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 5 to at least 25 [mu]m. It includes the calculation procedures required to determine the normal and hemispherical emittance of said object. 1.2 This test method includes calibration instructions for the spectrometer and procedures for selecting reflectance-reference standards. 1.3 This test method is generally suitable for any flat, specular-reflecting specimen. It is recommended for measuring emittance of architectural glazing materials such as glass (coated and uncoated), etc. This test method is not suitable for determining the emittance of an object that is transparent in the specified range of infrared radiation. 1.4 This test method is suitable for determining the emittance of an object based on blackbody weighting at a specified temperature (typically 23°C (73°F)), as would be needed to determine the thermal performance (U-Value/ SC/SHGC) of a window assembly. 1.5 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
