Test Pieces

Magnaflux test pieces contain artificial defects that simulate discontinuities when verifying MPI system performance.

Magnaflux tool steel test ring, test bar, pie gauge and quantitative quality indicator test pieces (QQIs) contain precisely defined artificial flaws used to verify that MPI equipment and processes are operating at accepted levels.
Specific applications for individual test pieces and their industry certifications/compliance can be found in their part descriptions.


MAGNETIC FLUX INDICATORS
Flexible indicators used to detect appropriate levels of magnetic field strength and directional orientation during the magnetic particle testing process. Each indicator contains three milled slots with widths of .0075", .009" and .010" that share a common depth.
The indicators are manufactured from permeable magnetic steel sandwiched between two brass plates and designed for repeated use in setting and monitoring magnetic field strength in wet and dry MPI applications.
Part Number: 008M004 (5 indicators per package)
Specifications Compliance: ASTM E709-08, ASTM E1444

QUANTITATIVE QUALITY INDICATOR TEST PIECES
Quantitative Quality Indicators (QQI) are magnetic particle test pieces with artificial defects used to verify field direction and relative strength. QQI's are also used to balance multi-directional fields and to increase productivity by minimizing magnetizing shots. The QQI indicator shims are packaged in sets of five.
Part Numbers:
* 625551: Standard QQI Model# KSC-230. Basic circular and crossed bar flaw configuration suitable for longitudinal and circular fields. Flaw depth of 30% of Shim thickness, .002 thick. Self adhesive.
* 625552: Miniature QQI Model# KSC-4-230. Similar to KSC230, except miniature design for small areas on test part. The four circles may be cut apart for individual use. Flaw depth of 30% of Shim thickness, .002 thick.
* 625553: Standard QQI Model# KSC-430. Basic circular and crossed bar flaw configuration suitable for longitudinal and circular fields. Flaw depth of 30% of Shim thickness, .004 thick.
* 625554: Variable Depth QQI Model# KSCT-234. Used for more quantitative work, three concentric circular flaws of differing depth. Flaws depth of 20%/30%/40% of Shim thickness, .002 thick. Self adhesive.
* 625555: Variable Depth QQI Model# KSC4-234. Used for more quantitative work, three concentric circular flaws of differing depth. Flaws depth of 20%/30%/40% of Shim thickness, .004 thick.
Specifications Compliance: ASTM E709-08, ASTM E1444, BPVC

MAGNETIC PARTICLE TEST BAR
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.
Part Number: 189838 - Magnetic Particle Test Bar
Specifications Compliance: ASTM E709-08, ASTM E1444

TOOL STEEL TESTRING
The Magnaflux Tool Steel Test Ring is a mag particle test Piece with pre-drilled holes to simulate subsurface discontinuities. It offers a reliable method of verifying magnetic particle system performance when actual test parts with discontinuities are not available.
Meets ASTM E1444 requirements.
Part Number: 159999 - Tool Steel Test Ring
Specifications Compliance: ASTM E709-08, ASTM E1444, BPVC

CONTINUOUS METHOS TEST BLOCK
The Magnaflux Continuous Method Test Block is used to check for proper magnetizing techniques on wet horizontal MPI units. Crack indications form on the test block when current flow and bath concentrations are at proper levels.
Part Number: 75130 - Continuous Method Test Block
Specifications Compliance: ASTM E709-08, ASTM E1444
