RE: Frequency of PSV calibration
The determination of frequency of testing is only part of a PSV maintenance program.
An integrated program includes classification of service, purchase and qualified use of a calibrated "test bench" and an accurate record keeping system for regulatory review.

Please note that, depending on management preferences, that it may be attractive to consider contracted services for this kind of program.

Hope that this helps...
Tell us about the size of your facility, where you are located and the type of program you envision...
