Daniel, I cannot find where the PED is in full effect for vessels that fall below the Bar L limit. In fact the PED goes as far as to say that the equipment must not bear a CE mark.

Good point about liquid v gas, the extinguisher is already specifically covered and must be considered at least as a cat 3. Outside of the extinguisher, a vessel is unlikely to become full of liquid but perhaps could be assumed as mostly gas. The PED does not appear to treat gas differently to a liquid, not as far as I can see at this stage.

Looks like I was reading the wrong table, the max limit for the Bar L is in fact 50 Bar L and not 200 as I first thought.

Are you going to Worthing? If so, we could be really sad and discuss further if I bring a copy of the PED. Did I really just say this!
