New ISO Standard

[jokers]

I just talked to someone with Immortal air and it seems that the ISO standard is no longer the gold standard that it was. According to them ISO is no longer a lifetime tank but rather a 15 year tank just like the DOT standard. Has anyone heard of this and is there documentation for this somewhere?

Iso standards are always shifting and evolving

Lol, so it didn't even last 15 years

ISO was never automatically a lifetime (really 38 year) certification. The specific model had to be approved to have that designation (as far as I could understand it). But as with most things in paintball, the telephone tag of the internet made people believe that any iso tank was automatically a lifetime tank.

Iso standards are to be met.....so this reads like a red flag for tanks not meeting standards

Ecapnation I think i should clarify I had always heard that an ISO tank was suppose to be designed to last 15 years plus. Where the DOT was to be designed to last 15 years. I did not know about the 38 year thing, i was in the camp that thought as long as the tank passed hydro every 5 years it was good for a lifetime. According to the gentleman at immortal air it was never truly lifetime unless you wanted to drop coin on the tank since after "*19" years the tank needed to be refreshed in order to continue on the 38 year path. The only company that could refresh a tank was the manufacturing company so if the tank was made overseas you would need to send it overseas, pay for the refresh and wait for it to come back. I do not think that the ISO tanks are made worse then the DOT only tanks or that the quality of the tanks will be going down rather they are no longer "lifetime".
*This may have been more or less I am not 100% sure and do not want to give out bad information.

I did not mention this in the initial post because I did not remember the exact year and up until 8 hours ago I had always thought of them as lifetime tanks.

If there’s an ISO, there’s documentation for it. They are literally the same thing.

I know that if there is someone who has an ISO tank that is born after 01/23 then it should have the new standard number on it, and if I had that number I could use that standard to find the documentation. I have tried searching for quite a few key terms "paintball ISO standard 2023" and a couple others I have found links to MCB, and a comparison between DOT and ISO on velocity paintball out of Ramona CA and a couple of Scam sites about best paintball gear in 2023 etc.

Wrong field.... I get a bunch of standards in my database when looking for the following.

Composite overwrapped pressure vessel

And

Composite wrapped pressure vessel iso certification

Can't link as it's on a limited access database to those with a certificate

It is not an ISO standard that they are actually referring to but an update to 49 CFR 180.207 Requirements for requalification of UN pressure receptacles. In the US we do not fall under UN pressure receptacle standards but the DOT regulations do reference them. As mentioned by SR_matt "Lifetime" = 38 years but the exemption no longer states "lifetime" and is clearly called out in 180.207 below as 15 years.

Taking out of the latest version of the document on https://www.govinfo.gov/app/details/...0-209/context:

§180.207 Requirements for requalification of UN pressure receptacles. (a) General. (1) Each UN pressure receptacle used for the transportation of hazardous materials must conform to the requirements prescribed in paragraphs (a), (b) and (d) in §180.205. (2) No pressure receptacle due for requalification may be filled with a hazardous material and offered for transportation in commerce unless that pressure receptacle has been successfully requalified and marked in accordance with this subpart. A pressure receptacle may be requalified at any time during or before the month and year that the requalification is due. However, a pressure receptacle filled before the requalification becomes due may remain in service until it is emptied. (3) No person may requalify a UN composite pressure receptacle for continued use beyond its 15-years authorized service life. A pressure receptacle with a specified service life may not be refilled and offered for transportation after its authorized service life has expired unless approval has been obtained in writing from the Associate Administrator. §180.207 tacle that is successfully requalified in accordance with the requirements specified in this section must be marked in accordance with §180.213. The requalification results must be recorded in accordance §180.215. (2) Each pressure receptacle that fails requalification must be rejected or condemned in accordance with the applicable ISO requalification standard. (b) Periodic requalification of UN pressure receptacles. (1) Each pressure recep(c) Requalification interval. Each UN pressure receptacle that becomes due for periodic requalification must be requalified at the interval specified in the following table:

For this discussion revolving around HPA tank certification this is true but as a general thing that's not entirely true. I work in propane and 49 CFR is a massive part of pretty much all hazmat rules and regulations. Yes DOT has their own standards that essentially replace many aspects of part 49 but there are plenty of areas where DOT does not have rulings and it then falls back to part 49.

This is why pretty much all mobile pressure receptacles fall under DOT jurisdiction while stationary tanks do not.

Yup, honestly the whole set of regulations pressure vessels fall under in the US is confusing (mobile and stationary) and there are so many exceptions, exemptions, loophole and endless loops it will drive you nuts. As I have said in other posts you can have a job just in interpreting and documenting those interpretations to protect your organization. I really haven't worked with mobile pressure vessels but have work more with stationary pressure vessels in a lab environment. We spent a lot of time trying to keep ourselves compliant so we could pass DOD audits since we were/are a military manufacturer/supplier. Thankfully that is no longer in my job description.
