Magnaflux Magnetic Particle Test Bar

The MPI Test Bar is a standardized test piece conforming to the requirements of NAVSEA T9074-AS-GIB-010/271 to demonstrate magnetic particle equipment performance.  The MPI Test Bar can be used with wet bench equipment, power packs, or magnetic yokes.  The test bar includes both surface and sub-surface flaws for use with AC, HWDC, and FWDC magnetizing currents.  Surface notches in two directions on each side of the bar are used to confirm both circular and longitudinal AC magnetization.  Multiple subsurface defects at progressive depths provide confirmation of HWDC and FWDC field penetration.  All machined flaws are epoxy filled to prevent magnetic particles from becoming trapped within the test bar.

SPECIFICATIONS

For use with systems conforming to:

  • NAVSEA T9074-AS-GIB-010/271
  • ASME BPVC Section V Article 7
  • ASTM E709
  • ASTM E1444
  • ASTM E3024

Position test bar in magnetizing equipment

  • Wet bench equipment: Clamp bar between head and tail stock
  • Power pack equipment: Use contact clamps to attach cables to test bar or place test bar inside cable wrap coil.

Magnetize test bar according to table provided on the Product Data Sheet. Apply particles to form indications. AC fields will detect surface flaws. HWDC and FWDC fields will detect subsurface flaws.

For yoke magnetization, position yoke legs on either end of the test bar.

Magnetize and apply particles to form transverse indications.
