EN 2103-1:1991
(Main)Aerospace series - Steel, nickel base and cobalt base alloy remelting stock and castings - Technical specifications - Part 1: General requirements
General Information
- Abstract
This standard specifies the general requirements for the manufacture, inspection and testing of steel, nickel base or cobalt base alloy remelting stock and castings. Particular requirements applicable to remelting stock and castings are defined in EN 2103-2 and EN 2103-3 respectively. Unless otherwise specified on the drawing, order or inspection schedule, the reference to EN 2103 only defines one quality level which is quality level 2 in table 4 or5 of EN 2103-3.

Overview
EN 2103-1:1991 - part of the CEN aerospace series - defines the general requirements for the manufacture, inspection and testing of remelting stock and castings made from steel, nickel‑base and cobalt‑base alloys. This Part 1 document provides the overarching technical specifications that apply across remelting stock and casting products; more specific provisions are given in EN 2103-2 and EN 2103-3. Where a drawing, order or inspection schedule does not specify otherwise, a plain reference to EN 2103 indicates quality level 2 (see table 4 or 5 of EN 2103-3).
Key topics
EN 2103-1:1991 establishes the foundational requirements that suppliers and manufacturers must address. Key technical topics include:
- Scope and definitions relevant to remelting stock and castings for aerospace use
- Requirements for manufacture, covering responsibilities of the producer for material condition and traceability
- Inspection and testing principles, defining that products must be inspected and tested to demonstrate conformance to agreed requirements
- Documentation and marking, including records, certificates and identification required for aerospace traceability
- Acceptance criteria and quality levels, noting the default to quality level 2 when EN 2103 alone is cited
- Reference to specific requirements in Parts 2 and 3 for remelting stock and for castings respectively
(EN 2103-1 sets general requirements only; specific test methods and parameter values are found in the companion parts.)
Applications
EN 2103-1:1991 is intended for use across the aerospace supply chain where remelted and cast metal feedstock is specified:
- Aerospace manufacturers and OEMs specifying raw material quality for components
- Foundries and remelters producing steel, nickel‑base or cobalt‑base alloy ingots, bars and castings
- Quality assurance and inspection teams establishing acceptance procedures and supplier audits
- Procurement and contracting for aerospace materials where standardized requirements and traceability are needed
Using EN 2103-1 helps ensure material consistency, traceability, and a common baseline of quality for aerospace remelting stock and castings.
