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

A PT indication that appears rounded and uniform typically suggests the presence of a non-defect feature or surface irregularity rather than an actual defect. In liquid penetrant testing, rounded and uniform indications can arise from various benign factors such as surface roughness, machining marks, or other non-relevant surface characteristics. These features can create patterns that resemble defects but do not indicate any flaw in the material's integrity or performance.

Categorizing such indications appropriately allows for accurate analysis and decision-making regarding the necessity of further inspection or remediation. By understanding the nature of these indications, inspectors can focus their attention on more relevant concerns and ensure efficient use of resources.
