Defined as a “Penetrant System Testing & Monitoring Panel” or referred to by many in the NDT community as TAM or PSM-5 Panels, they remain the most practical and dependable means for meeting MIL-STD-6866 paragraph 5.8.3 in daily monitoring your Fluorescent or Visible Penetrant Inspection system.

Five Star TAM Panels are manufactured to meet and exceed Pratt & Whitney Specification 146040 as well as comply with all required industry standards. In addition, Rolls Royce has recently approved Five Star TAM Panels (polished and grit) under the newly developed MK II program. Approval is in conjunction with RRP 58003 and TSD 594-J OP210.
