European foreword
This document (prEN 13445-14:2024) has been prepared by Technical Committee CEN/TC 54 “Unfired
pressure vessels”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
Introduction
This document is applicable to unfired pressure vessels or parts of pressure vessels made with additive
manufacturing (AM) processes.
This document is organized in a main part common to all additive manufacturing processes and
normative Annexes A to D.
Those Annexes are dedicated to specific AM processes and contain requirements relevant to specific
materials.
In this first edition of this document, only Annex A and Annex B are available. The other Annexes will be
added to this document during amendment or revision as they are completed.
The structure of the specific Annexes is described in Table 1.
