TAM / PSM 5 Panels

SPECIAL USAGE CONSIDERATIONS

Use a separate set of PSM-5^TM Panels for each penetrant system. Do not use penetrants with different sensitivity levels on the same set of panels.
PSM-5^TM Panels should be recalibrated periodically. One major company, which mandates the use of PSM-5^TM Panels, based on their experience, requires the calibration of their own, in-house panels approximately every six months. Experience has shown that recalibration requirements will vary with how much a panel is used and with how well it is maintained Sherwin Incorporated recommends that PSM-5^TM Panels be recalibrated, at least, annually.

Panels may be returned to the factory for cleaning, re-git blasting, crack measurement and recertification. Obtain quotes from Sherwin Incorporated.

PSM-5^TM Panels should be protected from scratches, thermal cracking, over-rubbing of grit blasted surface and exposure to corrosive materials.
With usage, there is a tendency for the smallest cracks to clog with residue and for the grit blasted area to lose its roughness. Please refer to the maintenance section.
