GB/T 45166-2024 "Non-destructive testing—Infrared thermographic testing—General principles" applies to the use of infrared thermographic testing technology in the non-destructive testing of various materials and components, specifying the overall requirements and general methods for testing. It clarifies that the testing principle involves using an infrared thermal imager to capture differences in surface temperature distribution to identify defects, covering technical requirements for testing equipment, surface treatment of samples, environmental control during testing, and other related aspects. The standard details the testing process (including preheating, data acquisition, and image analysis) and rules for evaluating results, providing unified guidance for infrared thermographic testing in fields such as metals, composite materials, and building structures.
