Need your help please.
We have two air cylinders (to be filled up to max 200 bar). We have had mixed information if we require or not CE certification because of the small volume of the cylinders.
The one air cylinder has a volume of 10.5 cm3 (0.01/Lt and the other has a volume of 112 cm3 (0.112/lt. The pressure we advise the customers to fill them with is 80- 120 bar and the maximum valve pressure recommended by the valve manufacturers is 200 bar. The small air cylinder is made of strong stainless steel and the bigger from strong steel.
We get conflicting answers to our requests about having or not certification. We are told that air cylinders under 0.450 liter volume don't require certification.
Some customers ask us if the cylinders are compliant with the EU Pressure Equipment Directive 97/23/EC and the Pressure Systems Safety Regulations 2000.
Could you please advise accordingly as we are not sure what is legal. I personally have read the directive but still can't understand it.
