Aerospace series - Identification marking methods for engine items - Engineering requirements

This standard describes the coding system for marks, the processes used to produce these marks, as well as the general marking requirements for the identification of aerospace engine items.
This document is applicable to items whose engineering drawing or design folder refers to EN 4301 for all issues that are not in contradiction with specific indications appearing on the engineering drawing or in the design folder.
This document is not applicable to items requiring an identification plate.

Luft- und Raumfahrt - Kennzeichnungsverfahren für Triebwerkbauteile - Technische Anforderungen

Diese Norm beschreibt das Verschlüsselungssystem für Kennzeichen, die zur Herstellung dieser Kennzeichen
angewandten Verfahren sowie die allgemeinen Kennzeichnungsanforderungen für die Identifizierung
