Non-Destructive Testing (NDT) Practice Test

What is typically evaluated during a calibration of NDT equipment?

1. The age of the equipment

2. The readability of the display

3. The performance and legal compliance

4. The costs incurred during inspection

The correct answer is: The performance and legal compliance

During a calibration of NDT equipment, the primary focus is on assessing the performance and ensuring legal compliance with relevant industry standards or regulations. Calibration is a systematic process that involves comparing the measurements produced by the NDT equipment against a known reference or standard to affirm that it operates accurately and reliably. This ensures that the equipment performs within specified tolerances, which is crucial for detecting flaws accurately and ensuring safety in applications such as construction, manufacturing, and maintenance. Legal compliance is equally important because many industries are governed by specific codes and standards that dictate how inspections should be carried out and what equipment must meet. Keeping records of calibration checks is essential for demonstrating that the equipment is up to date and maintained in accordance with such regulations. While factors like the age of the equipment, readability of the display, and costs involved in inspection may be relevant in assessing the overall effectiveness or practicality of the equipment, they do not directly pertain to the core purpose of calibration. Calibration is fundamentally about ensuring that the equipment functions correctly and meets the necessary criteria for producing valid and reliable results.
