This is a stainless steel panel, 0.090” thick and measuring 4 x 6 inches. A chrome plate strip runs the length of one side of the panel. Five crack centers are evenly spaced inthe chrome plating in order of magnitude; the largest is readily visible with lowsensitivity penetrants, while the smallest is difficult to observe even with highsensitivity materials. Adjacent to the chrome plate section is a grit blasted area of“medium roughness” to judge penetrant wash characteristics.

  • This is a stainless steel panel, 0.090” thick and measuring 4 x 6 inches. A chrome plate strip runs the length of one side of the panel. Five crack centers are evenly spaced inthe chrome plating in order of magnitude; the largest is readily visible with lowsensitivity penetrants, while the smallest is difficult to observe even with highsensitivity materials. Adjacent to the chrome plate section is a grit blasted area of “medium roughness” to judge penetrant wash characteristics.
  • The NR-5 Panel comes in two versions. Both versions are manufactured to Pratt-Whitney P/N TAM 146040 specifications. One has a chrome strip, which has beenlightly grit blasted in order to dull the surface. The chrome plate strip of the secondversion is not grit blasted.
  • NR-5 Panel processing meets MIL-STD-6866 and ASTM E-1417 requirements fordaily system check.
