Description 
The Magnetic Particle Examination Procedure defines a complete, field-ready, and compliant methodology for performing Magnetic Particle Testing (MT) using the yoke technique. Developed in accordance with ASME Section V and ASME B31.3, this procedure ensures reliable detection of surface and near-surface discontinuities on ferromagnetic materials while meeting all project and Client QA/QC requirements. 

Key Benefits 

• Standardized MT methodology fully compliant with ASME codes 
• Ensures reliable detection of surface and near-surface defects 
• Reduces inspection variability and non-conformities 
• Defines clear inspection steps, acceptance criteria, and controls 
• Ready to use and easily integrated into project quality systems
