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

The process of determining the cause of an indication is called?

1. Interpretation

2. Inspection

3. Evaluation

4. Determination

The correct answer is: Interpretation

The process of determining the cause of an indication is referred to as interpretation. In the context of liquid penetrant testing, interpretation involves analyzing the indications that appear after the application of the penetrant and the subsequent processing steps. Professionals use their knowledge and experience to assess whether these indications are relevant to a defect or flaw in the material being tested. This step is critical because it goes beyond merely recognizing the presence of indications; it requires a comprehensive understanding of the testing process, the materials involved, and the types of discontinuities that may occur. By effectively interpreting the indications, a technician can accurately convey whether a defect exists and its potential implications for the material's integrity or performance. Other options may describe components of the testing process, but they do not specifically denote the act of analyzing and concluding the significance of the indications.
