Reference Material for Nondestructive Photo-Infrared Thermography and Inspection Method of using the same

摘要

The present invention is an optical-infrared non-destructive testing for reference materials and relates to the non-destructive testing method using the same More particularly, the light-infrared non-destructive testing equipment can be optimized by arrangement and test conditions maximum performance is exhibited, in a state where optimized to easily inspect the defect on the actual subject light - infrared relates to non-destructive infrared reference substance for inspection and non-destructive inspection method using the same. ; To this end, the present invention includes the steps of forming a plurality of defective parts at regular intervals or non-uniform interval on the one surface of the metal plate having a predetermined area , between the defective portions are detected bipagwa minimum diameter by the testing device, maximum diameter, minimum diameter, and at the same time formed in a diameter between the maximum diameter can be detected by the testing device bipagwa minimum depth, maximum depth, the minimum depth to the maximum depth wherein the light formed by the depth-infrared imaging provides reference material and the non-destructive testing method for non-destructive testing using the same
