1.1 本规程涵盖了使用红外成像辐射计测量样品表面温度时测量和补偿反射温度的程序。 2. 1.2 这些程序可能涉及在存在加热或通电设备或两者的情况下使用设备和材料。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1 试样反射的红外能量可能会导致红外热像仪测量其表面温度的测量误差。提供了两种测量和补偿该反射温度误差源的程序，即反射法和直接法。 5.2 这些程序可在现场或实验室使用常用材料。 5.3 这些程序可用于任何具有所需计算机能力的红外辐射计。 5.4 由于样品的性质，重复性和再现性是主观的。然而，可以从中指定的复制程序的结果中推断出程序精度的度量 8.1.6 和 8.2.7 .

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 .
