Unfired pressure vessels - Part 6: Requirements for the design and fabrication of pressure vessels and pressure parts constructed from spheroidal graphite cast iron

This European Standard specifies requirements for the design, materials, manufacturing and testing of pressure vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than 100 bar and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidal graphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements, bosses etc. The allowable grades do not include lamellar graphite cast iron grades for ferritic and austenitic grades, which are explicitly excluded from this European Standard because of low elongation and brittle material behaviour, which requires the use of different safety factors and a different approach. NOTE 1 Austenitic spheroidal graphite cast iron grades are principally used for high and low temperature applications and for their corrosion resistance properties. NOTE 2 The allowable grades of spheroidal graphite cast iron are listed in Tables 3 and 4. Service conditions are given in Clause 4.

Unbefeuerte Druckbehälter - Teil 6: Anforderungen an die Konstruktion und Herstellung von Druckbehältern und Druckbehälterteilen aus Gusseisen mit Kugelgraphit

Der bestehende Text ist zu löschen und durch den wie folgt überarbeiteten Anwendungsbereich zu ersetzen:
Diese Europäische Norm legt Anforderungen an Konstruktion, Werkstoffe, Herstellung und Prüfung von Druckbehältern und Druckbehälterteilen aus ferritischem oder austenitischem Gusseisen mit Kugelgraphit fest, die für den Betrieb mit einem maximal zulässigen Druck PS gleich oder kleiner als:
-   100 bar bei Befüllung mit Gasen oder Flüssigkeiten der Gruppe 1 oder 2;
-   1 000 bar nur bei Befüllung mit Flüssigkeiten der Gruppe 2.
und einer maximalen Wanddicke von 60 mm vorgesehen sind. Die Grenzwerte für die Schalenwanddicke gelten nicht für die Dicke von Flanschen, Verstärkungen, Nocken usw.
ANMERKUNG 1   Austenitische Gusseisensorten mit Kugelgraphit werden hauptsächlich für Anwendungsfälle in hohen und niedrigen Temperaturbereichen und aufgrund ihrer Korrosionsbeständigkeit eingesetzt.
ANMERKUNG 2   Die zulässigen Gusseisensorten mit Kugelgraphit sind in den Tabellen 3 und 4 aufgelistet. Die Betriebs¬bedingungen sind in Abschnitt 4 angegeben.
Diese Europäische Norm, EN 13445 6, behandelt keine ferritischen und austenitischen Gusseisensorten mit Lamellengraphit mit einer Bruchdehnung  15 %, welche ausdrücklich ausgeschlossen sind. Anforderungen für die Verwendung von Gusseisen mit einer Bruchdehnung  15 % sind EN 15776 zu entnehmen.

Récipients sous pression non soumis à la flamme - Partie 6 : exigences pour la conception et la fabrication des récipients sous pression et des parties sous pression moulés en fonte à graphite sphéroïdal

Remplacer le Domaine d'application existant par le suivant :
La présente Norme européenne spécifie les prescriptions relatives à la conception, aux matériaux, à la fabrication et aux essais des récipients sous pression et de leurs parties sous pression, destinés à être utilisés à une pression maximale admissible, PS, inférieure ou égale à :
-   100 bar s'ils contiennent des gaz ou des liquides de groupe 1 ou 2,
-   1000 bar s'ils contiennent uniquement des liquides de groupe 2,
et d'épaisseur de paroi de la coque ne dépassant pas 60 mm, fabriqués en fonte à graphite sphéroïdal ferritique ou austénitique. La limite d'épaisseur de la coque ne s'applique pas à l'épaisseur des brides, renforcements, bossages, etc.
NOTE 1   Les nuances de fonte à graphite sphéroïdal austénitique sont utilisées principalement pour les applications à basse température et à température élevée, ainsi que pour leurs propriétés de résistance à la corrosion.
NOTE 2   Les nuances admises de fonte à graphite sphéroïdal sont énumérées dans les Tableaux 3 et 4. Les conditions de service sont données à l'Article 4.
La présente Norme européenne, EN 13445-6, n'incluent pas les nuances de fonte à graphite lamellaire destinées aux nuances ferritiques et austénitiques, qui sont explicitement exclues. Les exigences relatives à l'utilisation des fontes moulées avec un allongement, après rupture, inférieur ou égal à 15 % sont données dans l'EN 15776.".

European foreword
This document (EN 13445-6:2014/A1:2015) has been prepared by Technical Committee CEN/TC 54
“Unfired pressure vessels”, the secretariat of which is held by BSI.
This amendment to EN 13445-6:2014 shall be given the status of a national standard, either by
publication of an identical text or by endorsement, at the latest by April 2016, and conflicting national
standards shall be withdrawn at the latest by April 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 97/23/EU.
For relationship with EU Directive, see informative Annex ZA, which is an integral part of this
document.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland,

1 Modification to Clause 1 Scope
Replace the existing Scope with the following:
“This European Standard specifies requirements for the design, materials, manufacturing and testing of
pressure vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS,
equal or less than:
 100 bar when containing gases or liquids in group 1 or 2
 1000 bar when containing liquids in group 2 only.
and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic
spheroidal graphite cast iron. The thickness limitation of the shell does not apply to thickness of
flanges, reinforcements, bosses etc.
NOTE 1 Austenitic spheroidal graphite cast iron grades are principally used for high and low temperature
applications and for their corrosion resistance properties.
NOTE 2 The allowable grades of spheroidal graphite cast iron are listed in Tables 3 and 4. Service conditions
are given in Clause 4.
This European standard, EN 13445-6, does not include lamellar graphite cast iron grades for ferritic and

5 Modification to 5.2.2.1.1 Principle
Insert the following notes after the fifth paragraph:
“NOTE 1 Testing factors (0,8 or 0,9) are already accounted for in determining nominal design stress in 5.2.2.2 of
this Part 6.
NOTE 2 For non-circular sections (rectangular sections), see EN13445-3:2014, Clause 15 (see remark about
fatigue design and radius requirements in 5.2.2.7).”.
6 Modification to 5.2.2.1.3 to 5.2.2.1.6
Renumber 5.2.2.1.3 to 5.2.2.1.6 as follows:
“5.2.2.1.2.1 Design by formula (DBF)
5.2.2.1.2.2 Design by analysis (DBA)
5.2.2.1.2.3 Design by experiment (DBE)
5.2.2.1.2.4 Determination of the hydraulic burst pressure and maximum allowable pressure for
static loading”.
