Type 1 Reference Block for MPI
EN ISO 9934-2:2002
Type 1 Reference Block for MPI (also known as MTU Test Block No. 3) is a wet sensitivity calibration standard block for magnetic particle inspection (MPI), used to verify the detection capability and system status of magnetic suspensions/powders. It is the core quality control tool for non-destructive testing (NDT).
Core functionality
Sensitivity verification: Verify the defect display ability of magnetic powder/magnetic suspension, and determine whether the sensitivity has decreased due to aging or contamination.
System quality control: Daily/regular verification of MPI equipment, magnetic suspension concentration, and lighting conditions (UV/white light) to ensure compliance.
Benchmark comparison: Comes with a standard reference image, which compares the measured crack display with the benchmark to determine whether the system is qualified.
Consumables evaluation: Compare the testing performance of different brands/batches of magnetic powder and new and old magnetic suspensions.
Type 1 Reference Block for MPI usage and functional analysis
|
1. Verify the magnetization effect (magnetic field direction and intensity) |
Type 1 Reference Block for MPI 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.
Type 1 Reference Block for MPI is a key tool for ensuring the reliability, consistency, and traceability of magnetic particle testing results.
