ok, this makes a bit more sense. ive just spoke to a main dive center in reading. and this is what they say.
DOT test bottles are NOT allowed to be used in the uk by law. For them to be allowed, they would have to carry a HSE test.
The HSE test is to prove that the bottle is safe for use for its intended purpose. But as there is no recognised UK "intended use" code printed on US bottles they cannot be tested to uk HSE standard.
Its a case of america not accepting our standard, so we dont accept theirs.
in short even though the legislation has changed bringing us inline with europe, it does not mean we can use DOT tested bottles.
Anywhere that does test them to HSE is breaking the law.
As to HSE bottles, the length of test for paintball air systems is 5years, regarding the fact they are for "Dry Use" as in, not being used underwater. therefore the test is valid for longer.
as always i may be wrong but the guy i just spoke to seems to know what hes talking about.
its just insane that half the paintball world are using airsystems where the legislation regarding them is VERY hard to track down, and no-one seems to properly monitor or enforce it. We have to use dive centers for advise, not paintball distributers.
its mad
