4 Modification to Annex CC, “Safety requirements for components and
piping”
Replace Annex CC by the following text:
“
Annex CC
(normative)
Safety requirements for components and piping
The sealed system components can be considered pressure vessels as stated in the Pressure
Equipment Directive (PED) 2014/68/EU according to the classification in Table CC.1 and Table CC.2. If
the components or piping are classified as a Category II or a higher pressure vessel as stated in the
PED, then the requirements of Table CC.3 shall apply including the use of a Notified Body to the PED.
