European foreword
This document (EN 10025-6:2019+A1:2022) has been prepared by Technical Committee
CEN/TC 459/SC 3 “Structural steels other than reinforcements”, the secretariat of which is held by DIN.
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 May 2023 and conflicting national standards shall be
withdrawn at the latest by May 2023.
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 supersedes !EN 10025-6:2019".
This document includes Amendment 1 approved by CEN on 25 October 2022.
The start and finish of text introduced or altered by amendment is indicated in the text by tags !".
This document consists of the following parts, under the general title Hot rolled products of structural
steels:
— Part 1: General technical delivery conditions
— Part 2: Technical delivery conditions for non-alloy structural steels
— Part 3: Technical delivery conditions for normalized/normalized rolled weldable fine grain structural
steels
— Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels
— Part 5: Technical delivery conditions for structural steels with improved atmospheric corrosion
resistance
— Part 6: Technical delivery conditions for flat products of high yield strength structural steels in the
quenched and tempered condition
For a short transition period there will be a coexistence of EN 10025-1:2004 with EN 10025-2:2019 to
!EN 10025−6:2019+A1:2022", since the new EN 10025-1 has to fulfil the requirements of the CPR
and will therefore be published later. For this short transition period up-to-the publication of the next
edition of part 1 the following is to be taken into account for EN 10025-1:2004:
a) all dated and undated references to EN 10025-1:2004 to EN 10025-6:2004 are unchanged to this
version with following exception: In 9.2.2.1 the references are 8.3.1 and 8.3.2 instead of 8.4.1 and
8.4.2;
b) Clauses 5, 12 and 13 of EN 10025-1:2004 are no longer relevant.
The main changes with respect to the previous !version EN 10025−6:2004+A1:2009 of edition
EN 10025−6:2004" are listed below:
a) part 6 is now a stand-alone standard for technical delivery conditions including the preparation of
samples and test pieces, the test methods, the marking, labelling and packaging and the drawings;
b) for applications under the CPR this document and part 1 are used together;
c) requirements for elements not definded were added to 7.2.1 and 7.2.2;
d) Option 33 was added, Opti
