European foreword
This document (EN 13445-1:2021) has been prepared by Technical Committee CEN/TC 54 “Unfired
pressure vessels”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by November 2021, and conflicting national standards shall
be withdrawn at the latest by November 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
The list of all parts in the EN 13445 series can be found on the CEN website.
Although these Parts may be obtained separately, it should be recognised that the Parts are inter-
dependant. As such the manufacture of unfired pressure vessels requires the application of all the
relevant Parts in order for the requirements of the Standard to be satisfactorily fulfilled.
Corrections to the standard interpretations where several options seem possible are conducted through
the Migration Help Desk (MHD). Information related to the Help Desk can be found at http://www.unm.fr
(en13445@unm.fr). A form for submitting questions can be downloaded from the link to the MHD
website. After subject experts have agreed an answer, the answer will be communicated to the
questioner. Corrected pages will be given specific issue number and issued by CEN according to CEN
Rules. Interpretation sheets will be posted on the website of the MHD.
This document supersedes EN 13445-1:2014. This new edition incorporates the Amendments which
have been approved previously by CEN members, and the corrected pages up to Issue 5 without any
further technical change. Annex Y provides details of significant technical changes between this European
Standard and the previous edition.
Amendments to this new edition may be issued from time to time and then used immediately as
alternatives to rules contained herein. It is intended to deliver a new Issue of EN 13445:2021 each year,
starting with the precedent as Issue 1, consolidating these Amendments and including other identified
corrections.

Issue 1 (2021-05)
Introduction
EN 13445 specifies the requirements for design, construction, inspection and testing of unfired pressure
vessels. It defines terms, definitions and symbols applicable to unfired pressure vessels.
NOTE In EN 13445 the term pressure vessel includes the welded attachments up to and including the nozzle
flanges, screwed or welded connections, or the edge to be welded at the first circumferential weld at connecting
piping or other elements. The term unfired excludes vessels that are subject to direct generated heat or flame
impingement from a fired process. This does not exclude vessels subject to electrical heating or heated process
streams.
In Parts 2 to 5 only pressure vessels manufactured from steels and steel castings as detailed in Part 2 of
this standard are covered. Parts 6, 8, and 10 specifically deal with vessels of spheroidal graphite cast iron,
aluminium, and nickel, respectively, where special considerations apply.
Part 1
This part contains general information on the scope of the standard as well as terms, definitions,
quantities, symbols and units which are applied throughout the standard.
Part 2
This part deals with the general philosophy on materials, material grouping and low temperature
behaviour. It is limited to steel with sufficient ductility and, for components operating in the creep range,
sufficient creep ductility.
Part 2 also provides the general requirements for establishing technical delivery conditions and the
requirements for marking of material.
Part 3
This part of the standard gives the rules to be used for design and calculation under internal and/or
external pressure (as applicable), local loads and actions other than pressure. The rules provided are both
design by formulae (DBF), design by analysis (DBA) and design by experiment (DBE).
The part also sets the requirements for when fatigue analysis must be performed and the rules to be
followed when this is the case.
NOTE Collaborative work is in hand to harmonize flange design across European standards.
Part 4
This part of the standard specifies requirements for the manufacture of unfired pressure vessels and their
connections to non-pressure parts. It specifies requirements for material traceability, manufacturing
tolerances, welding requirements, requirements for permanent joints other than welding, production
tests, forming requirements, heat treatment, repairs and finishing operations.
Issue 1 (2021-05)
Part 5
This part covers all those inspection and testing activities associated with the verification of the pressure
vessel for compliance with the standard, including design review by the manufacturer and supporting
technical documentation, NDT and other inspection activities including document control, material
traceability, joint preparation and welding.
The level of testing is driven by the selection of the vessel testing group. Basically, the testing group
determines the level of NDT and the joint coefficient used in the design.
In terms of NDT, the overall philosophy has been the general adoption of EN ISO 5817:2014 quality level
'C' for predominantly non-cyclic loaded vessels and level 'B' for vessels subject to cyclic loadings.
Part 6
This part contains special rules for material, design, fabrication, inspection, and testing of pressure
vessels made from spheroidal graphite cast iron. In general the rules in the relevant parts of parts 2–5
apply with additions and exceptions outlined in this part.
Part 7
This part gives guidance on how to use the conformity assessment procedures in the Pressure Equipment
Directive 97/23/EC. This is a CEN Technical Report.
Part 8
This part contains special rules for material, design, fabrication, inspection, and testing of pressure
vessels made from aluminium and aluminium alloys. In general the rules in the relevant parts of parts 2–
5 apply with additions and exceptions outlined in this part.
Part 9
This part details the conformance of the whole EN 13445 series to ISO 16528-1 "Boilers and pressure
vessels — Part 1: Performance requirements". This is a CEN Technical Report. The first edition is limited
to vessels of steel construction, but will be amended later to include spheroidal graphite cast iron and
aluminium.
Part 10
This part 10 contains special rules for material, design, fabrication, inspection, and testing of pressure
vessels made from nickel and nickel alloys. In general, the rules in the relevant parts of parts 2–5 apply
with additions and exceptions outlined in this part.

0,5 bar gauge but may be used for vessels operating at lower pressures, including vacuum.
This document is not applicable to pressure vessels of the following types:
— vessels of riveted construction;
— vessels of lamellar cast iron or any other materials not included in Parts 2, 6, or 8 of the standard;
— multilayered, autofrettaged or pre-stressed vessels.
This document can be applied to the following pressure vessels, provided that account is taken of
additional and/or alternative requirements resulting from the hazard analysis and from rules or
instructions specific for:
— transportable vessels;
— items specifically designed for nuclear use;
