Magnetic Particle Test Bar MIL-STD-271

Description

Product information

The Magnetic particle test bar contains coarse and fine surface and subsurface defects in both directions. Meets or exceeds most industrial and military standards for artificial test specimens; complies with MIL-STD-271.

Main features:

This test bar is used as a test piece with artificial flaws to establish a field direction and determine adequate current levels using AC or DC current in wet horizontal magnetic particle bench units. The bar contains both fine and coarse defects, surface and subsurface defects, and longitudinal and transverse indications as required in some specifications.

This bar may be used to determine that the MPI procedure has the ability to detect a 1/16 inch long × .006 inch wide × .01 inch deep notch (maximum dimension) oriented 90° to the magnetic flux. It is made of low alloy steel and is filled flush with a non-conducting material to prevent mechanical holding of the magnetic particles. Meets or exceeds most industrial and military specifications for artificial test specimens. Including MIL-STD-271.
