What puzzles me is the requirement for re-certification of Halon systems- why is this necessary?
If the weight of the bottle and contents are within limits it should be OK. There is no internal corrosion, packing of powder, or pressure loss. What is it that limits a Halon system's ability to be re-filled after a certain date? I've read a study that reported many agencies (FAA, military, airlines, etc) are considering eliminating the required re-certification of Halon systems.
Can anyone explain this?
