Significance and Use
The emissivity of a specimen can cause surface temperature measurement errors. Two test methods are provided for measuring and compensating for this error source.
These test methods can be used in the field or laboratory, using commonly available materials.
These test methods can be used with any infrared radiometers that have the required computer capabilities.
1.1 These test methods cover procedures for measuring and compensating for emissivity when measuring the surface temperature of a specimen with an infrared imaging radiometer.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 These test methods 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 and health practices and determine the applicability of regulatory limitations prior to use.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
