Scope

1.1 These test methods cover procedures for measuring and compensating for reflected temperature when measuring the surface temperature of a specimen with an infrared imaging radiometer.

1.2 These test methods 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

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

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.
