Sherwin's PSM-5 Penetrant System Monitoring Panel enables you to determine the continued serviceability of liquid penetrant inspection systems quickly: fluorescent or visible; water-washable; post-emulsifiable; or pre-wash.
The panel ables you to confirm that all elements in the penetrant system (penetrant, emulsifier, wash, dryer and developer) are operating optimally. The panel will alert you to significant changes in your system's operating specifications.
Sherwin Incorporated manufactures each PSM-5 panel to P&WA TAM specifications 146040-1 (polish) or 146040-2 (grit). Each panel is made of stainless steel panel, 0.090" thick and measures 4 x 6 inches. A chrome or grit plated strip runs the length of one side of the panel. Five cracked starbursts are evenly spaced in the chrome or grit plating in order of magnitude; the largest is readily visible with low sensitivity penetrants, while the smallest is difficult to observe even with high sensitivity materials.
There are two different versions of the panel.
Polished – the chrome plated section is polished and its finish is mirror-like.
Grit Finish – the chrome section has been lightly grit blasted to dull its mirror finish.
The cracks in the test panel appear in the order of size; the largest being visible with low sensitivity materials and the smallest being difficult to detect with even the highest sensitivity materials. The biggest crack center is approximately 1/4" in diameter followed by the second biggest at 5/32", the third at 3/32", the fourth at 1/16", and the smallest at 1/32".
Next to the chrome plating is an oxide grit blasted area, used to monitor washability and background fluorescence.
While no two panels are exactly the same, each panel conforms to P&WA specifications as confirmed and certified by the Sherwin Incorporated laboratory.
