Thread: CIP vs SAAMI

With high pressure air tanks, there is a different standard in the US vs Europe too.

Can't remember which way around it is... Either it's the US testing bottles to a higher pressure (like 50% over what they're rated for) which freaks out the Europeans who therefore don't allow US tested HPA bottles to be used (fearing the testing might somehow compromise the bottles)... Or the US testing isn't high enough pressure and the Europeans therefore aren't convinced US tested bottles have demonstrated they can withstand potential mishaps.

Either way, different side of the pond, different standards. CIP is just the standard to which European firearms get proofed - in different units and using different equipment. That might require a CIP stamped firearm to have been tested with a proof cartridge that's hotter than that same cartridge would need to be, if it were submitted to SAAMI.
