European foreword
This document (prEN 4258:2021) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (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 is currently submitted to the CEN Enquiry.
This document will supersede EN 4258:1998.

Introduction
For the purpose of 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.---------------------- Page: 6 ----------------------

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 standard. Already existing material
standards for filler metals for welding and for brazing can continue to follow this organization.
