General Information
Overview
EN 2157-1:1993 is a critical standard within the aerospace series focused on steel forgings. Issued by CEN (European Committee for Standardization), this document specifies the general requirements for the manufacture, inspection, and testing of steel forging stock and forgings. It covers a range of products including hand forgings, forged blocks, rings, die forgings, and rolled rings.
This standard serves as Part 1 in a series, complemented by EN 2157-2 and EN 2157-3, which provide more detailed, specific requirements. Together, these standards ensure a harmonized approach to quality, inspection levels, and sampling frequencies in the aerospace industry.
Key Topics
- Scope of Application: Defines the general requirements applicable to forging stock and various types of steel forgings, emphasizing aerospace-grade steel materials.
- Manufacture Guidelines: Specifies the processes to ensure consistent quality in forging production, including stock preparation and forging techniques.
- Inspection Requirements: Establishes criteria for inspection procedures, including visual and dimensional checks essential for aerospace components.
- Testing Protocols: Outlines standard testing methods that must be adhered to, supporting mechanical properties verification and material integrity.
- Sampling Frequencies: Details the inspection frequency and sampling plans for quality control, referencing accompanying parts EN 2157-2 and EN 2157-3.
- Documentation and Compliance: Highlights the importance of documentation, traceability, and compliance with drawing, order, or inspection schedule specifications.
Practical Applications
EN 2157-1:1993 is vital for manufacturers and quality assurance teams involved with steel forgings in the aerospace sector. The standard's requirements help ensure that components such as structural parts, engine elements, and critical mechanical assemblies meet stringent aerospace safety and performance demands.
- Aerospace Manufacturers: Use the standard for consistent production and quality verification of steel forgings.
- Quality Control Units: Implement inspection and testing procedures aligned with the standard to maintain regulatory compliance.
- Suppliers of Forging Stock: Follow the general requirements to certify the material quality before delivery.
- Design Engineers: Reference the standard to specify material and quality prerequisites for forging components in aerospace designs.
- Regulatory Audits: Facilitate compliance verification through standardized documentation and testing records.
Applying EN 2157-1:1993 helps reduce material failure risks, enhances reliability, and maintains high standards necessary for safety-critical aerospace applications.
