How often should calibration of MPT equipment be performed?

Calibration of Magnetic Particle Testing (MPT) equipment is essential to ensure the accuracy and reliability of the tests being performed. The recommended frequency for calibration is based on the manufacturer's guidelines because these guidelines are established through rigorous testing and industry standards. Following the manufacturer's instructions ensures that the equipment operates within specified tolerances and maintains its effectiveness in detecting surface and near-surface discontinuities.

Adhering to a regular calibration schedule as outlined by the manufacturer helps maintain the equipment's precision and can prevent discrepancies in test results. This practice also addresses potential issues before they arise, rather than waiting for a performance complaint or a change in location, which could lead to undetected flaws in critical components.

While annual calibration may be adequate for some equipment and situations, it is not universally applicable. Each piece of equipment can have different requirements based on its technology and the specific conditions in which it is used, making reliance on the manufacturer's guidelines crucial.
