ActiveNon-destructive testing―Magnetic flux leakage testing―General principles
无损检测 漏磁检测 总则
Application Summary AI generated
This standard specifies the general principles for applying magnetic flux leakage (MFL) testing to detect surface and near-surface discontinuities in ferromagnetic materials. It is primarily used in industrial contexts such as pipeline inspection, storage tank floor scanning, and wire rope examination, where rapid, non-contact detection of corrosion, pitting, or cracks is required. The standard provides guidance on equipment, calibration, and procedures to ensure consistent and reliable results in field or manufacturing testing environments.
