Most excellent!
Since we have somehow managed to show that there is disagreement as to condemning a cylinder even at the agency level, your statement above (even if unsubstantiated) is gold.
Should I ever need to take one of my tanks in for VIP the first thing that I will do is to ask if it will be VIP'd by a licensed hydro test facility. If the answer is 'No We will VIP your tank here' (and they are not a requalifier) then they will be politely reminded that they cannot condemn my cylinder in any fashion if it fails their VIP. And they were fore-warned.
Thank you.
I would see some problems with that approach. The requalifer only does a vis to meet the requalifying needs. They do not do a vis to support nitrox. You shop will have to do that when it comes to looking for hydrocarbons with the light etc. When the tank leaves the hydro it is good for air. And by the way the hydro stamp is also the vis for the first period after hydro. Many shops argue that also that you have to have a sticker. what you have to have is proof of vis.which is part of the hydro and covered by the stamp'
