BS EN 4258:2024

This standard BS EN 4258:2024 Aerospace series. Metallic materials. General organization of standardization. Link between types of European Standards and their use is classified in these ICS categories:

• 49.025.01 Materials for aerospace construction in general
• 49.025.15 Non-ferrous alloys in general
• 49.025.05 Ferrous alloys in general
• 01.120 Standardization. General rules

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.
