Quantitative Quality Indicator (QQI) 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.
