No.
Components are not items of pressure equipment, and therefore are not subject to individual conformity assessment procedures.
For requirements on components to be used in pressure equipment, see PED Guidelines A-22 and G-19.
Note 1:
The final inspection including the proof test applies to the complete item of pressure equipment and not to the component itself.
Note 2:
If the component is not designed according to a harmonised standard, design information may also be requested by the equipment manufacturer.
Note 3:
There is no legal basis in PED for a Notified Body to issue a certificate of conformity for components.
