ASTM E1862

ASTM E1862 is a technical standard that addresses how to measure and compensate for reflected temperature when using infrared imaging radiometers. This matters because apparent infrared readings can be affected by surrounding thermal reflections, which may influence accuracy and interpretation. By providing a consistent practice for handling reflected temperature, the standard supports more reliable infrared imaging results in testing, inspection, and quality-focused applications.

Overview of ASTM E1862

ASTM E1862, Standard Practice for Measuring and Compensating for Reflected Temperature Using Infrared Imaging Radiometers, provides guidance for working with infrared measurements where reflected thermal energy can affect the observed signal. Its purpose is to help users account for reflected temperature so that radiometric imaging is more consistent and technically defensible. The standard is especially relevant when evaluating surfaces or objects that may not emit infrared energy uniformly, making measurement setup and interpretation important.

Common use cases of ASTM E1862

This standard is commonly used in infrared thermography workflows where accurate surface temperature interpretation is important. It may apply when using infrared imaging radiometers for inspection, evaluation, or troubleshooting of equipment and materials. ASTM E1862 is also useful in procedures that require better control of measurement conditions, especially when reflections from nearby objects or the environment could influence the apparent thermal image and affect the reliability of the recorded data.

Benefits of using ASTM E1862

Using ASTM E1862 can improve consistency in infrared temperature measurements by giving users a recognized practice for addressing reflected temperature effects. That can support more dependable comparisons between inspections, reduce uncertainty in reported results, and strengthen quality control or compliance documentation. For organizations that rely on infrared imaging radiometers, the standard helps make measurement practices more repeatable and easier to align across teams, instruments, and test conditions.
