Tank standards what a mess!!

[Hickdive]

The tank manufacturer could just put all three stamps on the cylinders when their made.. that way it's good to go every where... Sounds simple.... I'm sure the standards are really close

Jim..

Would a cylinder made to US standards not require an imperial neck thread whilst one to EU standards needs a metric?

No, I don't think threading would affect the testing standard... It would be like " This tank meets or exceeds standards EU# and DOT# and then mark the neck metric or imperial... I don't know what the differences are in the tanks, But I would guess they are all made the same and then marked and threaded as needed for export to wherever... A Lot of things are marked kg/lb or psi/bars or foot lbs/newtons or liters/gallons.. But then again ... That would be to simple....

I wasn't referring to testing standards but to the manufacturing standard.

I'm not at all convinced that a cylinder made to EU standards and stamped as such could have an imperial neck thread.

Consequently, I'm not convinced that a cylinder not made to EU standards could be legitimately tested to EU standards.

It will happen, sometime after the US adopts the metric system.....

Canada uses metric US imperial. There seems to be no problem for our tanks to have both DOT and TC stamps on the same neck one in imperial and the other in metric.

To the OP these issues are not managed by PADI or SSI its the government that takes care of it.
If you own a compressor and do not use the tanks in the commerce no one even cares whether you have a hydro or what kind of tank it is.

If you were using 6351 alloy tank without a current hydro, vis, and eddy, I might want to stand on the other side of a truck from you in the parking lot while suiting up. With other tanks, not so much.

I think that kind of ignorant owner would not probably even make to the parking lot

I would care if I was to borrow the compressor to fill my tank.. But then again, Im just fond of not being blown up

The risk to the owner/user is not all that bad, its the poor bastard filling the tank who would most likely take the damage.

Yes and I was talking about the case when the diver owns the compressor and fills their tanks

In Australia 6351 alloys have effectively been banned, nobody will fill, inspect or test them. In fact all alloys over 15 years old have been classed as unsafe and will not be filled tested or inspected. Having said that they are still out there and it has become a problem for new players. People that have them and haven't used them for a while are finding out that they can't be filled and then selling them on eBay without disclosing the age or the fact that they can't be used.
