Magnetic Particle Testing
Surface and near-surface discontinuity detection in suitable ferromagnetic materials.
Safety boundary: this page explains integrity concepts only. It does not provide live electrical work, pressure-equipment repair/testing, confined-space entry, radiation-source handling, machinery operation or hazardous inspection procedures.
What this topic covers
Surface and near-surface discontinuity detection in suitable ferromagnetic materials.
Core ideas
Magnetic fields interact with discontinuities in ferromagnetic material and can create detectable leakage fields.
The method is material-limited and cannot be applied universally.
Surface condition, field direction and technique affect sensitivity.
Program tradeoffs
Coverage, access, technique limitations and uncertainty should be visible in the final record.
What good evidence looks like
Inspection findings need a closed path to engineering assessment, maintenance, monitoring or documented acceptance.
Lifecycle perspective
Formal code inspection and risk-based inspection require competent specialists and current standards.
