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: (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.
