I have posted information on SCBA tanks with videos explaining some of this. I cannot speak specifically to PCP gun reservoirs, more specifically tube styled reservoirs. However, when it comes to bottles my assumption is that the fall under the same regulations as SCUBA tanks (aluminum bottle reservoirs) and SCBA tanks (carbon fiber bottle reservoirs). Based upon that assumption, watch the videos in the following links.



The only tube-styled PCP reservoir that I’ve seen the pressure rating addressed in was the American Air Arms Evol and I forgot where I read about it. I believe that it is made of titanium. I wish I had a more direct answer for you. I’m sure others will come along with more information.
 
I was asked this question and I did not know the answer.

Breathing air cylinders and other high pressure vessels are required to undergo a periodic hydrostatic test and certified as being safe to use. There is no such thing for PCP rifle reservoirs. I read somewhere that a 10 liter 300 bar cylinder contain the kinetic energy of a 3 ton vehicle moving at 100 km/h. That can cause a lot of damage and harm and even death.

My question is, are there any standard pressure safety margin these reservoirs are manufacture to? Or does every manufacturer just comply by his own standards whatever that might be, if any?

Did anybody do actual pressure failure test on any commercial PCP reservoir? I know some reservoirs have actual burst plates but most don't.
Google is your friend - add DOT regulations for high pressure vessels and OSHA regulations and US Navy hydrostatic testing and the rabbit hole is deep. In some locations they will inspect your guns air cylinder for proper testing / documentation
 
@Klaas I don’t know what sort of bottles are on your PCPs or where they came from, but the USA has their own regulatory standards. In videos I’ve watched, it has been said and shown that SCUBA tanks (and SCUBA styled tanks) are most often stamped with their pressure rating and have some other sort of indication of what sort of gas the tank has been used for or designed to have been used for. Carbon fiber SCBA tanks often have a paper label with pertinent information like expiration dates and regulator code info on said label that is protected by coats of a clear resin finish. Again, I don’t know what is permissible in your country and I don’t have solid information for you. Some things I don’t feel confident that I can accurately recall or I have forgotten and do not wish to speculate any further. What I have stated is my understanding. I have nothing else for you. I hope that you find the information you seek.

All tubes and bottles I saw have the pressure rating from the manufacturers on it, yes. But that does not fall under or indicate any regulations that must be followed. I am not talking or asking about scuba tanks or smaller tanks to fill a pcp from. I am talking about the reservoir on the rifle itself.

If there is such standards for pcp rifles, where can I read about it. How often must it be inspected be certified test centrums? Speculation is not an firm answer.

In short, without documented regulations there are no regulations or standards. It seems to be that there are none.
Pressurized tubing falls under ASME testing standards. Most standardized tubing has already been tested and rated and these standards are to be applied for all tubing made of the same materials, diameter and wall thickness. As long as they are using standard tubing the specs have already been determined and it is up to the manufacturer to test the tubing in their own applications. All airgun manufacturers use standard tubing such as DOM or Aluminum with standard diameter and wall thickness.
 
That is the problem. No regulatory agency to inspect it.
It's already been inspected. And yes, regulatory agencies to inspect manufacturing do exist.

What's your real question? Look up the agency I mentioned and you'll find that they do have standards for periodic inspection. As said before, google is your friend and if you say that's what a forum is for you're just asking someone else to Google it for you.

If you don't know by now I cannot help you.


How often do you send your rifle to a test centrum to be inspected?
Never because I have eyes and a brain and common sense and I know what I am looking at.

If you question the integrity of any of the reservoirs on your guns it is up to you to have them tested. That is your answer whether you like it or not.

Stop taking things so personally.
 
So why do you keep on saying there are regulations when there are not?
There are. I already answered the periodic inspection recommendation. Consumers do not need a regulating agency to hold their hand for the products they are using. How do know when it's time to change your tires? Do you have a guy that comes around and inspects them for you? There are recommendations and sometimes even regulations but it's up to you to adhere to them. As I said, the answer is that it's your responsibility to have a questionable reservoir tested. That is the answer. Case closed.
 
Why don't you make thread titled "I wish there was a person who could hold my hand and tell me when my stuff is in need of inspection" lol. That's where you're headed whether you can see it or not.
It's astonishing how many people come on here to ask a question, not get the answer they think they should, and then go on the defensive. Would pompus be a good word to describe such a person? I need to dust off my thesaurus...
 
So because I did not want to bow down to his will he blocked me. What a brave man.
No, he just got tired of hearing you repeat yourself over and over and have a condescending tone about it.

I'm pretty close to hitting ignore too...

It has nothing to do with bravery, but you apparently are the type that looks for a confrontation if you believe it revolves around being "brave".
 
Because he keeps on repeating things that are NOT relevant. I asked where is the regulations about PCP and he keeps on about scuba tanks. Or don't you understand as well?

So do it, what are you waiting for? There is noting you say that I will miss.
Abrasive... that's the word I was thinking.

Good day sir, hope you enjoy your lack of friends around here.
 
Some of the more recent FX CF bottles have wording on them to have them inspected every 5 years. Probably others as well since those bottles are outsourced. So there's that part.

Concerning any government agency enforcing safety standards: I'm quite content with there being no regulations on my airguns, and would very much like it to keep it that way, thank you very much. I'm in charge of my own safety and have zero need for a nanny state to try to control more aspects of our lives.
 
So what is this forum for then?

Anyway, I did a internet search and did not find anything on PCP reservoir safety standards. Can you give links to PCP reservoir standards.
Well the simplest of searches netted numerous hits but: https://www.govinfo.gov/content/pkg/CFR-2014-title49-vol3/pdf/CFR-2014-title49-vol3-sec180-209.pdf

seriously we are here to help but not..... well you know
 
This is as good a place as any I guess to mention.

Those of you who degas your guns by unscrewing the gauge to let air out are asking for big trouble.

I don't care if you've done it 1000 times. It only takes once.
then you might be shocked to know that very few manufacturers provide a degassing point.
 
Thanks.
Since I am not in USA some things like this does not come up in my search results. I cannot open and read what does not come up in the results.

The thing is, as I said before, I asked about PCP reservoirs, not scuba tanks that gets thrown to me every time.

Conclusion - PCP's reservoirs are not under the same regulations as other vessels like scuba tanks and it is better for us that way.





i could google myself silly but you get the ideas..... search until you find specifically what your looking for for YOUR country/state etc...
