1.1 This practice covers procedures for measuring and compensating for emissivity when measuring the surface temperature of a specimen with an infrared imaging radiometer.2

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 These procedures may involve use of equipment and materials in the presence of heated or electrically-energized equipment, or both.

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


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.
