I was wondering if the markings REE 89 and BSE 100 mean that the tanks is a 100cu. Thanks Ed

The REE number is used in the wall stress calculations durign the hydro test to determine if the tank can still qualify for a "+" rating to allow a 10% overfill. It is a very good thing to have on the tank as it is otherwise very hard to get a hydro tester to plus rate a tank as many of them seem to be math impaired and do not want to do the wall stress calculations manually.

Ed, I believe that the ability to overfill a tank is only allowed when a "+" stamp follows the Hydrostatic test date.
Everything else is codes for tank manufacturing, testing, and material.
Hey DA, can you elaborate on what the REE number actually means? For example if it says REE89, what does this number represent during a hydro test?
REE= Rejection Elastic Expansion.
It's for the hydro tester. It's the maximum that the tank can expand after the hydro inspection. It'll deform a certain amount after the hydro, and this is the volume that it'll be bigger by and still pass.

Even with the REE the tester still has to do a little math, subtracting the permanent expansion from the total expansion, to get the elastic expansion.
Note that even when the tank has the REE stamped on it the hydrotester may not know what to do with the information, so if you want the "+' you have to be sure before the tank is tested that the hydrotester can do it, and will. If they say they'll "try", or "look into it" odds are not good you will get a plus.

Yes it does. Not all Faber tanks have this marking but the newer ones do. Without the BSE marking the volume will be listed in litres. Don't ask me what BSE stands for because I have no clue.

So here is my example:
I have a Faber LP95. The REE number is 75. So according to the quote above, the tank cant expand more than 75.
75 what?
Dash Riprock:
REEs are shown in milliliters. Even in imperial tanks

AH, there you go. Wow, so in a language I can understand, my tank cant expand such that it ever increases its total capacity by more than 2.53 ounces.
cool, thanks
