Magnetic Particle Test Pieces
Magnetic Particle Performance Evaluation Devices

These test pieces for magnetic particle inspection will help you maintain your mag particle process by verifying magnetic particle performance. Use to check for mag particle deterioration, to compare different magnetic powders, to verify sensitivity or visibility or to assure field direction and strength.

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.

Specifications

• ASTM BPVC
• ASTME709
• ASTM E1444

Part Numbers 

• 008M004 (5 indicators per package)

Quantitative Quality Indicator Test Piece Shims
Quantitative Quality Indicators (QQI) are magnetic particle test piece shims 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.

Specifications

• ASTM BPVC
• ASTM E709
• ASTM E1444

Part Numbers (all QQIs come in a set of five shims)

• 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. Set of five.
• 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. Set of five.
• 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. Set of five.
• 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. Set of five.
• 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. Set of five.

Tool Steel Ring
The Tool Steel Ring / Ketos 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.
