Standard Practice for Measuring and Compensating for Emissivity Using Infrared Imaging Radiometers

Importancia y uso:

5.1 The emissivity of a specimen can cause surface temperature measurement errors. Two procedures are provided for measuring and compensating for this error source.

5.2 These procedures can be used in the field or laboratory, using commonly available materials.

5.3 These procedures can be used with any infrared radiometers that have the required computer capabilities.

5.4 The values of emissivity are defined only in terms of the procedure for the purpose of process control and nondestructive evaluation of materials.
