What might happen if an interface is not properly accounted for in testing?

The accurate detection of defects is critically dependent on understanding the various interfaces present in the testing environment. When an interface is not properly accounted for, it can lead to misinterpretation of the signals received during testing.

For instance, interfaces such as the boundary between different materials can cause reflections, refractions, and scattering of sound waves that are used in phased array testing. If the interface characteristics are not well understood or adequately defined, it can obscure the true nature of any defects within the material being tested. This can result in missed defects or false positives, leading to an overall decrease in the reliability of the inspection results.

In contrast, enhancements such as clarity in readings, reduction in testing time, or improved signal strength are not direct outcomes of neglecting interface considerations. Instead, these aspects are more likely to be compromised when interfaces are overlooked, underscoring the importance of accounting for all interfaces during testing to ensure accurate and dependable defect detection.
