Why might calibration standards differ across industries in Eddy Current Testing?

Calibration standards in Eddy Current Testing can indeed vary significantly across different industries due to the influence of varying industry regulations and the distinct types of materials being tested. Each industry may have specific requirements and safety standards that dictate how non-destructive testing should be conducted, which informs the calibration process.

For instance, in aerospace, the materials used, such as titanium and aluminum alloys, require calibration standards that are different from those used in the automotive industry, where materials are often different and have varied electrical properties. Additionally, industries like oil and gas may have stringent regulations aimed at ensuring safety and integrity that necessitate unique calibration standards as well.

The variety in material types and compositions means that the electromagnetic properties which Eddy Current Testing relies on can differ greatly. This necessitates tailored calibration approaches to ensure that the testing results are valid and reliable within the context of each specific industry’s operations, hence leading to the observed differences in calibration standards.
