PVC Pressure Rating database?

So I was buying some joints and connectors and stuff in PVC Piping, but the pressure rating imprinted on the sides isn't really clear anywhere. I do see lots of numbers and codes though, so I was thinking maybe its some sort of identification about the exact part in some database. Particularly pressure ratings?
Anyone know?

Usually fittings are not marked with actual pressure ratings, but pipes are. Ex: A 1/2" length of pipe might say "600psi @ 73*F"
As longs as your fittings are marked with NSF-pw then they're fine.

Well.. I did find this for a particular piece I'm holding in my hand. It's a 3" 90 degree elbow.
It's got written on it, among many many other things, "B182.1". So, I looked this up on the internet and lowe n behold I found it haha.
B182.1-06
Plastic drain and sewer pipe and pipe fittings
1 Scope
This Standard specifies requirements for
(a) plastic drain and sewer pipe and plastic pipe fittings with pipe stiffness of 275, 320, or 625 kPa, including both single-wall, coextruded, and coextruded dual-wall pipe with a smooth interior;
(b) single-wall, non-corrugated, perforated plastic pipe and plastic pipe fittings with a pipe stiffness of 200 kPa;
(c) coextruded dual-wall perforated plastic pipe with a smooth interior, corrugated exterior, and a pipe stiffness of 200 kPa; and
(d) solvent cement.
Notes:
(1) Industrial waste disposal lines should be installed only with the specific approval of the regulatory authority because chemicals not commonly found in drains and sewers, and temperatures greater than 60 °C, can be encountered.
(2) Guidance on the relationship between pipe stiffness and end use of pipe is given in Annex A.
Heres the website incase anyone runs into the same problem as moi. It's also got some info on ABS pipes.

My only question is when it says 275, 320, or 625 kPa, how do you tell which one it is??

625 kPa is only around 90 psi, so at its best, it's not safe (in my opinion) for a pneumatic.

Guess I gotta find a different store.

Interesting I followed the link you gave. The info box on that page is just the scope of what the PDF they are selling contains. Notice that it says $375.00 is the price and it's 296 pages long. Way too expensive for me, but I bet that PDF would make for some interesting reading. The link you gave was for the Thermoplastic Nonpressure Piping Compendium. You could use that reference to learn about how much pressure nonpressure piping can withstand...
I think an even more interesting book they have for sale is the Thermoplastic Pressure Piping Compendium

Good find bigotry2, I wonder if there are any good USA references like this out there...
