Scope

This standard specifies the commonly used nondestructive testing technologies and quality control requirements for aerospace materials and parts and components. This standard applies to nondestructive testing technologies commonly used in aerospace products, such as X-ray, ultrasonic, magnetic powder, penetration (coloring, fluorescence), eddy current, acoustic emission, laser holography, industrial CT, leak detection, and visual inspection. Other nondestructive testing technologies can be implemented as a reference.
