Foreword
This document (prEN 4500-004:2025) has been by the Technical Committee ASD-STAN/D04
“Material”.
This document is currently submitted to the CEN Enquiry
This document will supersede EN 4500-004:2024.
EN 4500-004:2024:
— addition of the lines 4.3 "Further intended processing" and 5.2 "Dimensional standard" in the body
of the document and in Annex D;
— addition of introductory sentences to Table 1 in Annex C to highlight the fact that the table is a
normative element and that all the documents that it lists shall be applied;
— overall editorial modifications to give clarity on the normative or informative nature of the
references made to other documents or Annexes;
— restructuring of the document and simplification of the Template to achieve a single continuous
table.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
Introduction
This document is part of the series of EN metallic material standards for aerospace applications. The
general organization of this series is described in EN 4258.
The EN 4500 series (Aerospace series — Metallic materials — Rules for drafting and presentation of
material standards) is composed by the following documents:
— General rules EN 4500-001;
— Specific rules for aluminium, aluminium alloys and EN 4500-002;
magnesium alloys
— Specific rules for heat-resisting alloys EN 4500-003;
— Specific rules for titanium and titanium alloys EN 4500-004;
— Specific rules for steels EN 4500-005;
— Specific rules for filler metals for welding EN 4500-002 to EN 4500-005;
— Specific rules for filler metals for brazing EN 4500-006.
Basis for the drafting of all European standards is CEN/CENELEC Internal Regulations — Part 3:
Principles and rules for the structure and drafting of CEN and CENELEC documents.
