Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the CEN Management Centre or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as theofficial versions.CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre:

EN ISO 643. The requirements and definitions of EN 10028-1:2007 + A1:2009 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. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

N), b) elevated temperature quality (P.NH), c) low temperature quality (P.NL1) and d) special low temperature quality (P.NL2). SIST EN 10028-3:2009

EN 10028-1:2007 + A1:2009 apply. If the purchaser does not indicate a wish to implement any of these options at the time of enquiry and order, the products shall be supplied in accordance with the basic specification (see also EN 10028-1:2007 + A1:2009). 1) tests in the simulated normalized condition (see 8.2.2); 2) delivery of products in the untreated condition (see 8.2.3); 3) maximum carbon equivalent value (see 8.3.3); 4) tensile properties for increased product thicknesses (see Table 4, footnote c); 5) modified values for ReH and Rm
for grades P460NH and P460NL1 (see Table 4, footnote d)
6) application of the Rp0,2 values of Table 5 for the corresponding P.NL1 and P…NL2 grade (see 8.4.2); 7) Rp0,2 values at elevated temperatures for increased product thicknesses (see Table 5, footnote b); 8) specification of a minimum impact energy of 40 J (see NOTE to 8.4.1 and Table 6); 9) HIC test in accordance with EN 10229 (see 8.7); 10) mid thickness test pieces for the impact test (see Clause 10); 11) verification of impact energy for longitudinal test pieces (see clause 11); 12) use of test solution B for the HIC test with agreed acceptance criteria (see Annex A). 7.3 Example for ordering 10 plates with nominal dimensions, thickness = 50 mm, width = 2000 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 x 2000 x 10000 – EN 10028-3
P275NL2 - Inspection certificate 3.1. or 10 plates – 50 x 2000 x 10000 – EN 10028-3
1.1104 – Inspection certificate 3.1.
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 a minimum yield strength ≥ 460 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 the
steel grades P275NH, P275NL1, P275NL2, P355N, P355NH, P355NL1 and P355NL2 (see 3.1 in EN 10028-1:2007 + A1:2009). 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
