PED - Simple Pressure Vessel discrepancy
PED - Simple Pressure Vessel discrepancy
(OP)
I am attempting to determine if a tank (pressure vessel) that I am shipping to Europe needs to be CE Marked. The volume of the tank is 95 liters. It will be charged to a pressure of 6.2 bars. The contents will be a silicon-water mixture.
The Simple Pressure Vessel Directive 87/404/EEC Article 3.1 indicates that the vessel should be CE Marked if it exceeds 50 bar-liter. Bar-liter is detemined by multiplying the tanks volume by its pressure. My tank will be 95x6.2 = 589 bar-liter. The Pressure Equipment Directive (PED) 97/23/EC Article 3.1.1.(b) indates that the tank does not have to be CE Marked because it contains a non-toxic fluid <10,000 bar-liter.
Are there any suggestions on how to resolve this issue? Do I need a CE Marked tank? If I do not need the CE Mark, I will not get it because this is a special tank and I am not aware of any manufactures in the USA that will supply a CE Tank like this.
Thank You,
Bill Johnston

Simple pressure vessels are limited to the containment of air or nitrogen (or liquids at low temperature with air or nitrogen pocket).

RE: PED - Simple Pressure Vessel discrepancy
What is the nature of the vessel? Is it an assembly? Does its final function cause it to be considered as a safety device? All safety accessories are classified as Category IV.
Article 3 identifies whether an item should be identified as SEP and CANNOT carry a CE mark, or if it should be marked.
The directive also states that (and I would urge you to look at the guidelines on this at http://ped.eurodyn.com , especially guideline 9.9) a vessel produced to sound engineering practice should be produced '... in accordance with the sound engineering practice of a Member State in order to ensure safe use.'
Hope this helps (though with the PED it rarely does).
