Flat products made of steels for pressure purposes - Part 3: Weldable fine grain steels, normalized

This European Standard specifies requirements for flat products for pressure equipment made of weldable fine grain steels as specified in Table 1.
NOTE 1   Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in accordance with EN ISO 643.
The requirements and definitions of prEN 10028-1:2014 also apply.
NOTE 2   Once this European Standard is published in the EU Official Journal (OJEU) under Directive 97/23/EC, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 97/23/EC is limited to technical data of materials in this European Standard (Part 1 and this Part 3 of the series) and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 97/23/EC are satisfied, needs to be done.

Flacherzeugnisse aus Druckbehälterstählen - Teil 3: Schweißgeeignete Feinkornbaustähle, normalgeglüht

Diese Europäische Norm legt Anforderungen an Flacherzeugnisse für Druckbehälter aus den schweißgeeigneten Feinkornbaustählen nach Tabelle 1 fest.
ANMERKUNG 1   Unter Feinkornbaustählen werden Stähle verstanden, die bei Prüfung nach EN ISO 643 eine Ferritkorngröße von 6 oder feiner aufweisen.
Zusätzlich gelten die Anforderungen und Begriffe in EN 10028-1:2017.
ANMERKUNG 2   Nach Veröffentlichung dieser Europäischen Norm im EU Amtsblatt (OJEU) unter der Richtlinie 2014/68/EU ist die Annahme ihrer Konformität mit den grundlegenden Anforderungen (ESR) der Richtlinie 2014/68/EU auf die technischen Daten von Werkstoffen in dieser Europäischen Norm (Teil 1 und der entsprechende Teil der Normenreihe) beschränkt, und es darf nicht angenommen werden, dass damit die Eignung des Werkstoffs für ein bestimmtes Ausrüstungsteil festgestellt ist. Folglich müssen die in dieser Werkstoffnorm angegebenen technischen Parameter im Hinblick auf die konstruktiven Anforderungen dieses bestimmten Ausrüstungsteils ermittelt werden, um damit zu verifizieren, dass den ESR der Richtlinie 2014/68/EU entsprochen wird.

Produits plats en aciers pour appareils à pression - Partie 3 : Aciers soudables a grains fins, normalisés

La présente Norme européenne spécifie les prescriptions relatives aux produits plats pour appareils à pression en aciers à grains fins aptes au soudage, telles que spécifiées dans le Tableau 1.
NOTE 1    Par «aciers à grains fins», on entend les aciers ayant une grosseur de grain ferritique 6 ou plus fin, déterminée conformément à l'EN ISO 643.
Les prescriptions et définitions de l’EN 10028-1:2017 s’appliquent également.
NOTE 2    Dès lors que la présente Norme européenne est publiée dans le Journal Officiel de l’Union européenne (JOUE) en lien avec la Directive 2014/68/UE, la présomption de conformité avec les exigences essentielles de sécurité de la Directive 2014/68/UE se limite aux données techniques des matériaux spécifiées dans la présente Norme européenne (partie 1 et l’autre partie pertinente de la série) et ne suppose pas l’adéquation des matériaux avec un appareil en particulier. Par conséquent, il doit être procédé à l’évaluation des données techniques spécifiées dans la présente norme de matériaux par rapport aux exigences concernant la conception de cet équipement spécifique, afin de vérifier que les exigences essentielles de sécurité de la Directive 2014/68/UE soient satisfaites.

Ploščati jekleni izdelki za tlačne posode - 3. del: Variva drobnozrnata jekla, normalizirana

Ta evropski standard določa zahteve za ploščate izdelke za tlačno opremo, izdelano iz varilnih drobnozrnatih jekel, kot je določeno v razpredelnici 1.
OPOMBA 1   Drobnozrnata jekla se obravnavajo kot jekla s feritnim zrnom velikosti 6 ali manj, ko so testirana v skladu s standardom EN ISO 643.
Uporabljajo se tudi zahteve in definicije standarda prEN 10028-1:2014.
OPOMBA 2   Ko bo ta evropski standard objavljen v Uradnem listu Evropske unije (OJEU) v okviru Direktive 97/23/ES, bodo zagotovila o skladnosti z osnovnimi varnostnimi zahtevami (ESR) Direktive 97/23/ES omejena na tehnične podatke o materialih, navedene v tem evropskem standardu (1. delu in tem 3. delu skupine), standard pa ne bo zagotavljal ustreznosti materiala za določen element opreme. Zato bo potrebno oceniti tehnične podatke, podane v tem standardu za materiale, glede na zahteve zasnove določenega elementa opreme, da se zagotovi, da so spoštovane osnovne varnostne zahteve Direktive 97/23/ES.

1 Scope

This European Standard specifies requirements for flat products for pressure equipment made of

weldable fine grain steels as specified in Table 1.

NOTE 1 Fine grain steels are understood as steels with a ferritic grain size of 6 or finer when tested in

accordance with EN ISO 643.
The requirements and definitions of EN 10028-1:2017 also apply.

NOTE 2 Once this European Standard is published in the EU Official Journal (OJEU) under Directive

2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is

limited to technical data of materials in this European Standard (Part 1 and the other relevant part of the series)

and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of

the technical data stated in this material standard against the design requirements of this specific item of

equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done.

7.3 Example for ordering

10 plates with nominal dimensions, thickness = 50 mm, width = 2 000 mm, length = 10 000 mm, made

of a steel grade with the name P275NL2 and the number 1.1104 as specified in EN 10028-3, to be

delivered with inspection certificate 3.1 as specified in EN 10204:

10 plates – 50 × 2000 × 10000 – EN 10028–3 – P275NL2 – Inspection certificate 3.1.

8.1 Steelmaking process
See EN 10028-1:2017.
8.2 Delivery condition

8.2.1 Unless otherwise agreed at the time of enquiry and order (see 8.2.3), the products covered by

this document shall be supplied in the normalized condition.

For steels with minimum yield strength ≥ 420 MPa, delayed cooling or additional tempering may be

necessary for small product thicknesses and in special cases. If such a treatment is performed, this shall

be noted in the inspection document.

8.2.2 Normalizing may, at the discretion of the manufacturer, be replaced with normalizing rolling for

all steel grades covered by this standard. In this case, additional tests on simulated normalized samples

with an agreed frequency of testing may be agreed at the time of enquiry and order to verify that the

specified properties are complied with.
