Hi:
This response is from a microwave vendor, so you've been forewarned! :-)
That said, it seems analogous ISO-9000 certification: each lab is
allowed to make its own determination as to the meaning of
"periodically;" the procedure should be documented and assigned AND (and
here's the key part) adhered to and logged! I've seen some labs with
very nicely thought out and documented procedures, who got written up
because they didn't follow their own procedures.
When CAP began their microwave leakage measurement requirement, it
specified "at least" yearly, and EBS recommended quarterly. (Arbitrary?
Maybe.) As for reproducibility, I feel that yearly is not enough, daily
or weekly is probably excessive, but depending upon your lab's volume,
monthly or quarterly should be sufficient, unless anything unusual is
noted (blown fuse, etc.).
Hope this helps!
