Le présent document spécifie l'organisation générale des normes de matériaux métalliques pour les applications aérospatiales, leurs liens avec les autres types de normes européennes et leur utilisation.
Il correspond au niveau 0 (voir 4.2).
À compter de la date de publication du présent document, les spécifications des différents produits de soudage et de brasage peuvent être rédigées dans une seule norme au lieu de normes de matériaux distinctes. Les normes de matériaux existantes pour les métaux d'apport destinés au soudage et au brasage peuvent continuer à suivre cette organisation.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee ASD-

STAN.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations

which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other

language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC

Management Centre has the same status as the official versions.

CEN members are the national standards bodies of 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, Turkey and

United Kingdom.

Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are

aware and to provide supporting documentation.

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.

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.
