The Magnaflux® KDS Panel is one type of Known Defect Standard that can be used for the daily System Performance Check as specified in ASTM E1417 and AMS 2647. It is provided with certification which includes indication sizes and description. The KDS Panel is a tool for monitoring a penetrant system for sudden changes, similar to a TAM Panel. It is not used to evaluate penetrant sensitivity.

The KDS Panel is constructed of 0.085-inch thick stainless steel, 4 inches by 6 inches. A strip of heavy chrome plating is deposited on one side of the panel. The plated area contains five evenly spaced “starburst” crack patterns, which are progressively smaller in size, progressing from the top. The remaining front surface is grit-blasted to a uniformly roughened surface finish. This area is suitable for evaluating residual penetrant background characteristics.

No two panels have identical crack patterns. Chrome plating thickness variations and random residual plating stresses prevent exact duplication of manufactured panels.
