Unbefeuerte Druckbehälter - Teil 3: Konstruktion
Dieser Teil 3 der Europäischen Norm legt die Anforderungen an die Konstruktion von unbefeuerten Druckbehältern
nach EN 13445-1:2014 und hergestellt aus Stählen nach EN 13445-2:2014 fest.
EN 13445-5:2014 gibt im Anhang C Bedingungen für die Konstruktion von Zugangs- und Besichtigungsöffnungen,
von Verschlüssen und besonderen Verschlusselementen.
ANMERKUNG Dieser Teil gilt für Konstruktion und Berechnung von Behältern vor der Inbetriebnahme. Er kann auch, mit
entsprechenden Anpassungen, für Berechnungen oder analytische Nachweise im Betrieb verwendet werden.
Récipients sous pression non soumis à la flamme - Partie 3 : Conception
Cette partie de la présente norme européenne spécifie les exigences relatives à la conception des récipients sous
pression non soumis à la flamme couverts par l’EN 13445-1:2014 et construits en aciers conformes à
l’EN 13445-2:2014.
L’Annexe C de l’EN 13445-5:2014 spécifie les exigences relatives à la conception des ouvertures d’accès et
d’inspection, des mécanismes de fermeture et des éléments de verrouillage spéciaux.
NOTE Cette partie s'applique à la conception des récipients avant mise en service. Elle peut être utilisée pour les calculs
ou l'analyse en service sous réserve d'apporter les ajustements appropriés.

Overview
EN 13445-3:2014/prA12 - Unfired pressure vessels - Part 3: Design (CEN draft amendment A12) specifies requirements for the mechanical design of unfired pressure vessels covered by EN 13445-1:2009 and constructed from steels in accordance with EN 13445-2:2009. This draft amendment, prepared by CEN/TC 54, proposes targeted changes to design rules (notably removal of a previously prescribed multiplier for testing group 4) and is submitted for enquiry; it is currently a draft and may be revised. The document is intended for design before putting vessels into service and can be adapted for in-service calculations with appropriate adjustments. See Annex ZA of EN 13445-3 for relationship with EU Directive(s).
Key topics and requirements
- Scope and applicability
- Design rules for unfired pressure vessels made of steels covered by EN 13445-2:2009 and within the scope of EN 13445-1:2009.
- Nominal design stress and material limits
- Defines maximum allowed values of nominal design stress for pressure parts (Table 6-1), including recent amendment changes affecting notes and multipliers.
- Testing group considerations
- Draft amendment A12 removes the previous instruction to multiply the nominal design stress by 0.9 for testing group 4 (modifications to subclause 6.1.3 and Table 6‑1).
- Access, inspection and closures
- Design requirements for access and inspection openings, closing mechanisms and special locking elements are referenced in EN 13445-5:2009, Annex C.
- Design versus in-service use
- Primary application is pre-service design; document may be applied to in-service analysis subject to appropriate adjustment.
Practical applications and users
Who uses EN 13445-3:
- Pressure vessel designers and mechanical engineers performing structural calculations and pressure part sizing
- Fabricators and manufacturers applying standardized design criteria for steel vessels
- Inspection and certification bodies reviewing designs against CEN requirements
- Project managers and procurement specialists ensuring contract specifications reference recognized European design rules
Practical benefits:
- Harmonized design rules for safety, reproducibility and regulatory alignment
- Clear material and stress limits to support calculation, welding and fabrication decisions
- Guidance that links to inspection-opening design and EU Directive compliance (see Annex ZA)
