Aerospace series - Metallic materials - General organization of standardization - Link between types of European Standards and their use
This document specifies the general organization of metallic material standards for aerospace applications, their links with other types of European standards and their use.
It corresponds to level 0 (see 4.2).
From the date of publication of this document, specifications for different welding and brazing products can be written in only one standard instead of separated material standards. Already existing material standards for filler metals for welding and for brazing can continue to follow this organization.

Ta dokument določa splošno organizacijo standardov za kovinske materiale za uporabo v aeronavtiki ter povezavo z drugimi vrstami evropskih standardov in njihovo uporabo.
Ustreza ravni 0 (glej točko 4.2).
Od datuma objave tega dokumenta je mogoče specifikacije za različne izdelke za varjenje in spajkanje zapisati samo v enem standardu, namesto v ločenih standardih za materiale. Že obstoječi standardi za dodajne materiale za varjenje in spajkanje lahko še naprej sledijo tej organizaciji.

European foreword
This document (EN 4258:2024) has been prepared by ASD-STAN.
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document shall be given the status of a national standard, either by publication of an identical text
or by endorsement, at the latest by February 2025, and conflicting national standards shall be
withdrawn at the latest by February 2025.
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 4258:1998.
The main changes with respect to the previous edition are as follows:
— EN 4258 (P1), 08/1998 — This revision is to allow to write filler metal standards in only one
document.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this document: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
Introduction
For the purpose of the standardization of metallic materials, ASD-STAN had originally based the
organization of this standardization on a system which provided strong interlinks between a material
standard referring to EN 2500 and its supporting standards.
Since these links did not allow the partial use of the supporting standards, the following amendments
have been introduced to ensure that:
— strongly interlinked standards are limited to those strictly necessary to ensure coherency;
— other standards may be either used, or replaced by standards of another origin, at the purchaser's
discretion.
The basic change in these links is that the dimensional standards and designation standard for semi-
finished products, where applicable, have been dissociated from the material standard. Additionally,
product qualification procedures are being introduced.
Pending the updating of the standards, these two organizations exist in parallel:
— the original one described by EN 2500;
— the new one described in this document (see Annex A and Annex B).
To enable progressive updating of the standards, an intermediate procedure is to be followed, as
described in Annex C, pending full introduction of the new organization.
1 Scope
This document specifies the general organization of metallic material standards for aerospace
applications, their links with other types of European standards and their use.
It corresponds to level 0 (see 4.2).
From the date of publication of this document, specifications for different welding and brazing products
can be written in only one standard instead of separated material standards. Already existing material
standards for filler metals for welding and for brazing can continue to follow this organization.

generic term used to indicate that the material as supplied does not necessarily have any relation to the
exact form, dimensions or condition in which that material is used as a final component
Note 1 to entry: This term may refer to one of the following types:
a) wrought products (e.g. bars, sheets, sections) or cast products (e.g. rod, amorphous brazing foil)
characterized by their form within a range of standardized dimensions;
