NDT Evaluation Checklist: Written Procedures for Magnetic Particle Inspection Mobile App
Magnetic particle inspection is used to find surface and near surface defects in ferromagnetic materials.
How does it work?
Fluorescent and nonfluorescent, wet and dry methods are available but most aviation applications involve use of the wet fluorescent method in a batch processing system which is the most sensitive. Parts are usually magnetized in at least two directions at right angles to each other and demagnetization of the part is required. During certification, written procedures should be required, which are applicable to the part or group of parts being tested. During audit/evaluation and surveillance the adherence to the procedures should be verified. Procedures may include the elements within the NDT Evaluation Checklist:Written Procedures for Magnetic Particle Inspection.
