MTU-3 MPI Reference Block Type 1
EN ISO 9934-2:2002
Cracked Test Piece for the Evaluation of Magnetic Particles
The MTU-3 Test Block is used to check the sensitivity of magnetic particle materials, assess material degradation and assess bath contamination. This two-sided block has a variety of indications ranging in size from small to large and each block has a completely unique crack pattern that mimics natural cracking. Can be used with fluorescent or visible particles. For application, ensure the block is free from dust, oil and other repellent materials before applying a well-mixed inspection medium. Compare your results with the supplied reference photograph before cleaning your block immediately to avoid permanent indications.
Usage and functional analysis
|
1. Verify the magnetization effect (magnetic field direction and intensity) |
MTU-3 test blocks are usually made of materials with high magnetic permeability, When the test block is placed on the surface of the inspected workpiece and magnetized together with the workpiece, The operator determines the direction of the magnetic field on the surface of the workpiece by observing which directions of defects display magnetic traces. For example, if only radial cracks are visible, it indicates that the magnetic field is circumferential; If only concentric cracks are displayed, it indicates that the magnetic field is radial. |
|
2. Evaluate the comprehensive sensitivity of the system |
The artificial defects on the test block are very subtle and can only be clearly displayed when the entire detection system (current value, magnetization method, magnetic suspension concentration, cleanliness, lighting conditions, etc.) is in good condition. |
|
3. Daily performance verification |
·Before starting the testing work every day, or after replacing the testing process and equipment, using MTU-3 test blocks for a quick calibration is an important quality control step to ensure the reliability of the testing results. This meets the regulatory requirements of high standard industries such as aerospace, nuclear power, and pressure equipment. |
|
4. Compare the performance of different magnetic suspensions |
·By using the same MTU-3 test block and the same magnetization specification, the performance of magnetic suspensions (including fluorescent and non fluorescent) from different batches or suppliers can be compared. A better performing magnetic suspension will result in clearer defect display and higher contrast on the test block. |
During the magnetic particle testing process, the MTU-3 Type I test block quickly and intuitively verifies and confirms whether the comprehensive sensitivity of the entire testing system (including equipment, magnetization method, magnetic suspension performance, and operating process) meets the required standards, and displays the direction of the magnetic field on the workpiece surface.
The MTU-3 MPI Type I test block is a key tool for ensuring the reliability, consistency, and traceability of magnetic particle testing results.
