Standard Practice for Measuring and Compensating for Reflected Temperature Using Infrared Imaging Radiometers
ORDER

Scope

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

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

1.3 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.

Significance and Use

5.1 The infrared energy that is reflected by a specimen can cause measurement errors for an infrared thermographer measuring its surface temperature. Two procedures are provided for measuring and compensating for this reflected temperature error source, the Reflector Method and the Direct Method.

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 Due to the nature of the specimens, the repeatability and reproducibility are subjective. However, a measure of the precision of the procedures can be inferred from the results of the replicate procedures specified in 8.1.6 and 8.2.7.
