Generally correct and will most likely be the case for us in paintball but the ISO standard allows testing and certifying for more then 15 years but there are special requirements and markings required and DOT has adopted this in 49 CFR 178.71.
The fact they are aligning of standards between DOT and ISO is really good for us. There are a lot of different bottle sizes out there that were never certified under DOT that have have not been available to us before.
