You must have a leak inspection once per calendar year until the owner or operator can demonstrate through the leak rate calculation that the leak rate has not exceeded 10% for 1 year.
So in other words, if you have a system that you had to add refrigerant to it, you fix the leak, you repair the leak, and you have to come back at least once a year to prove that it does not have a leak.
You have to leak test the entire system
