Liquid Penetrant Testing Level 2 (PT-2) Practice Exam

Indications caused by design or construction of the test piece are classified as?

1. Relevant

2. Non-relevant

3. False

4. Real

The correct answer is: Non-relevant

Indications caused by the design or construction of the test piece are classified as non-relevant indications. This classification arises because these indications do not represent flaws or discontinuities that could affect the integrity or performance of the material or component being tested. Instead, they are inherent characteristics of the test piece itself, such as welds, rivets, or other intentional features. During liquid penetrant testing, the goal is to identify discontinuities that could compromise structural integrity, so distinguishing between relevant and non-relevant indications is critical. Non-relevant indications may distract from the true defects present and can lead to unnecessary rework or further testing. As a result, it is essential for technicians to recognize the difference and focus on indications that are indicative of real flaws rather than those arising from the material's design or construction.
