Vague memory that the ICC certifys pressure vessels every 5

During WW2 they were considered a strategic material and thus are all 
"leased" and can be recalled by the Feds in an emergency.
Don't buy a used tank that has a hydrostat date more than 5 years old 
unless you are figuring in the cost of testing and chance of failure.
The gas outfit i deal with has changed hands 6 times since I started 
dealing with them. They have no real idea of how many tanks they own, much 
less the serial #s. When they behave poorly, one can quietly , er, correct 
the situation.
