Patterns
Standards for magnetic particle testing (MT) are reference specimens with known discontinuities or defects, used for equipment calibration and verification of the inspection system’s sensitivity. They allow checking proper magnetization of the tested material and the effectiveness of defect detection, ensuring repeatability and reliability of MT inspection results.
MTU no.3 pattern – to quality control of freshly prepared or used magnetic suspensions (black and fluorescent). Made of hard magnetic steel.
Berthold pattern – for checking strength magnetic field, direction and equality of magnetic field and sensitivity black and fluorescent magnetic suspensions.
Ketos-bar pattern
Fluxa pattern - to sensitivity control of fluorescent magnetic suspensions.
Ketos-ring pattern - for checking quality of magnetic suspensions and dry powder.
Octagon pattern ASTM / ASME - to determine the direction the magnetic field lines, choice and control strength magnetic field
