Frequently Asked Questions

What is the difference between inspection and testing?

Inspection evaluates characteristics against requirements, while testing determines characteristics under defined conditions. Many inspection activities use measurements or test methods.

Is calibration the same as adjustment?

No. Calibration establishes a measurement relationship with a reference under stated conditions. Adjustment may be performed separately if an instrument needs correction.

What does ISO/IEC 17025 cover?

It is the international competence standard for testing and calibration laboratories, addressing areas such as competence, impartiality and consistent operation.

Can one NDT method find every flaw?

No. Different NDT methods respond to different materials, defect orientations and physical effects.

Does the site explain how to perform industrial radiography?

No. Ionizing radiation is hazardous and regulated, so radiography content stays conceptual.
