The TB10-SP Magnetic Weight Lift / Defect Test Bar provides for the 10 pound AC weight lift calibration of magnetic particle inspection yokes.
Bar weight is certified and traceable to NIST standards.
The reverse side of the TB10-SP bar contains two artificial defects (a 0.5″ diameter press fit pin, and a 0.016″ x 0.032″ transverse slot, filled will epoxy and machined flush). Demonstration of actual defect indications is very useful for visual and operational performance purposes.
NOTE: The TB10-SP bar has no center bolt hole for mating with additional TB10 bars.
