PED Classification Questions - CE marking conflict
(OP)
We have a number of products that fall under the PED, since they have a maximum allowable pressure of greater than 0.5 bar g.
These products appear to fall under the Vessel and Piping category of the PED, so we follow the Pressure Accessories part of the flow chart. All of our products that are over .5 bar g contain a volume of less than 0.1L, which isn't covered by any of the 4 charts for Vessels. Therefore, we're treating them such that the nominal size DN is more appropriate than the volume. In this case, the PED says to treat it as Piping. Am I right so far?
Treating these products as piping, none of them have a nominal size DN greater than 25, so they get qualified as SEP. Is that right?
Okay, now we have a case where all our PED products are category SEP, and the PED states that SEP equipment must not be CE marked. However, much of this same equipment is required to be CE marked for EMC safety. Anybody know how that is to be handled?
Thanks,
Tim

RE: PED Classification Questions - CE marking conflict
Note that for SEP equipement you had to add use instructions and your identification. you don't need to CE mark the product.
If you had to mark the equipement CE according to another directive, you do it like this :
CE NNNN RR/DD (for PED CE 0089 97/23)
where NNNN : NoBo number identification
RR : Date of reference
and DD : reference
(this is not official, it what I observed and what we do)
For EMC, you had to mark : CE NNNN EMC. If no NoBo required you mark CE EMC.
If You have to mark to others directive, for example PED and EMC : CE 0089 97/23
CE 0089 EMC
Hope will help
