Epirb testing

Where in the CFR can one find where it’s written the correct times before and after the hour to test an EPIRB? Or is it somewhere else?

When operating a 406 MHz EPIRB self-test, the EPIRB is allowed to radiate a single burst which is specially coded so that it is ignored by the
COSPAS-SARSAT system. The EPIRB must never be tested by actual operation. If it is accidentally activated in the transmit mode, then
it should be turned off at once and the false alert cancelled by calling the nearest U.S. Coast Guard Station and have them contact the nearest
Rescue Coordination Center.


Thanks for the Link!
