SIST EN 2236:2001

Overview

SIST EN 2236:2001 is an international standard developed by the Slovenski inštitut za standardizacijo (SIST) that specifies the technical requirements for headed, close tolerance shank pins made of alloy steel specifically for the aerospace industry. This standard ensures that these aerospace pins meet strict technical specifications for high-performance, safety, and reliability in advanced applications, such as aircraft manufacturing and maintenance. SIST EN 2236:2001 is applicable whenever referenced by a relevant product standard or definition document.

Key Topics

• Close Tolerance Shank Pins: Features and dimensional requirements for headed pins designed for precision fit in aerospace assemblies.
• Alloy Steel Material: Specifications focus on alloy steel, offering enhanced strength, durability, and resistance to tough operational environments.
• Technical Requirements: Outlines manufacturing, mechanical properties, and criteria that must be met to ensure that the pins are suitable for aerospace applications.
• Quality Assurance: Ensures consistency and reliability through standardized production and quality control measures.
• Reference Application: The standard is intended for use when cited in product standards or specific technical documents.

Applications

Headed close tolerance pins specified in SIST EN 2236:2001 are widely used in the aerospace sector, particularly in applications where precise alignment, structural integrity, and secure fastening are critical. Typical uses include:

• Aircraft Assemblies: Providing dependable shear and alignment in fuselage, wing, and undercarriage structures.
• Maintenance and Repairs: Ensuring correct replacement parts that conform to stringent aerospace engineering requirements.
• Aerospace Component Manufacturing: Supporting compliance with international specifications during the production of high-performance aircraft parts.
• Other High-Precision Industries: While primarily intended for aerospace, the close tolerance and robust properties are suited for defense, automotive, and precision engineering sectors where similar requirements exist.

Related Standards

Several other international and European standards complement or reference SIST EN 2236:2001, ensuring comprehensive coverage of fastener and pin requirements in aerospace and related industries:

• EN 2236:1992: Original European standard equivalent to SIST EN 2236:2001, upon which the Slovenian version is based.
• EN ISO 8734: Parallel standards for parallel pins, suitable for a broader range of mechanical applications.
