What does NDT (Non-Destructive Testing) involve?

NDT, or Non-Destructive Testing, is specifically designed to evaluate materials or components without causing any damage. This method allows for the assessment of structural integrity, material properties, and detecting defects while preserving the item being tested for future use. Techniques used in NDT include ultrasonic testing, radiographic testing, magnetic particle testing, and eddy current testing, among others.

Choosing C accurately reflects the primary purpose of NDT, which is to identify potential issues in materials or structures while preventing any detriment to their functionality or structural integrity. Thus, it supports continuous quality assurance and maintenance without the need for repair or replacement of the tested items.

The other options describe methods that either cause damage to the material or strictly limit the scope of inspection, which does not align with the fundamental principle of non-destructive testing. NDT is pivotal across various industries, including aerospace, automotive, and manufacturing, allowing for safety assessments without sacrificing the items being evaluated.
