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

Indications resulting from sources other than a discontinuity are referred to as?

1. Relevant

2. Non-relevant

3. False

4. Real

The correct answer is: False

The term used to describe indications that arise from sources other than a discontinuity is "non-relevant." This classification is essential in liquid penetrant testing because it helps in differentiating between signals that indicate an actual flaw and those that do not point to any discontinuity within the material being inspected. Indications can be affected by various factors such as surface texture, contamination, or other materials in the vicinity of the test area. These non-relevant indications can lead to misinterpretations if they are not correctly identified and analyzed. Understanding this distinction is crucial for an effective testing process, as it ensures the inspector recognizes which indications require further investigation and which do not. By categorizing indications as non-relevant, testers can focus on the indications that truly indicate flaws, thereby enhancing the accuracy and reliability of the testing process. This knowledge is vital for ensuring that inspections based on liquid penetrant testing yield meaningful results that contribute to the integrity of the inspected components.
