Dear Experts,

May a manufacturer use welding procedures not qualified to ASME IX for ASME VIII Div-1 designed but non-stamped vessels also required PED 2014/68/EU CE Marking ?

Thanks.

For ASME VIII Div. 1 designed but non-stamped vessels that fall under PED 2014/68/EU, welding procedures do not need to be qualified to ASME Section IX.

According to PED requirements, the Procedure Qualification Record (PQR) must be qualified according to ISO 15614-1, and the qualification must be approved by a Notified Body.

The Welding Procedure Specification (WPS) can be based on the design code (e.g., ASME VIII Div.1), but the PQR qualification must follow ISO 15614-1 for CE marking.

In summary: For PED compliance, use ISO-qualified procedures approved by a Notified Body; ASME IX is optional if the vessel is not ASME-stamped.

  For PED CE‑marked vessels, ASME IX alone is not sufficient. Welding procedures must be qualified to EN ISO 15614‑1 (PED requirement), even if the vessel design follows ASME VIII Div‑1. ASME IX procedures may be reused only if supplementary testing proves equivalence and the Notified Body approves
