Overview

SIST EN 3086:2019 is a European standard developed by CEN that provides a designation method for aerospace hose assemblies, limited to 15 digits. This standard ensures a consistent and concise coding system for identifying hose assemblies used in aerospace and defense fluid systems. The designation system enhances clarity, interoperability, and traceability of hose assemblies across the aerospace industry. Compliance with SIST EN 3086:2019 supports uniformity in product identification, facilitating easier manufacturing, procurement, maintenance, and quality assurance processes.

Key Topics

• Size Codes: Hose assemblies are classified using metric and inch size codes, representing nominal diameters. For example, code ‘A’ corresponds to DN03 or −2 inch size, while code ‘V’ corresponds to DN105 or 64 inches.
• Length Codes: Lengths are denoted in millimeters with three-digit codes. Lengths over 1,000 mm include a prefix letter for extended range identification (e.g., A00 to A99 for 1000 to 1099 mm). This supports precise length specification in a compact form.
• Coupling Configuration Codes: Multiple tables define coupling configurations based on coupling types and sealing interfaces, enabling consistent description of hose end connections. Codes from ‘A’ to ‘R’ represent different assembly configurations for single or dual type couplings.
• Angular Orientation Codes: For hose assemblies with angular couplings (e.g., double elbows), a three-digit numeric code specifies the anti-clockwise angular orientation from a defined datum position. This ensures accurate spatial orientation in installations.
• Sleeve Material Codes: Sleeve presence and material are identified by a code (e.g., ‘A’ for hose without sleeve), providing important information about protective coverings used on hose assemblies.
• Codification Examples: The standard includes examples demonstrating the assembly coding process reflecting size, length, coupling, orientation, and sleeve material.

Applications

SIST EN 3086:2019 is essential for industries involved in the design, manufacturing, and maintenance of aerospace fluid and hydraulic systems. Its designation system has practical applications in:

• Aerospace Manufacturing: Standardized hose assembly identification simplifies ordering, inventory control, and quality assurance.
• Maintenance and Repair: Precise designation enables quick identification and replacement of hose assemblies during aircraft servicing.
• Supply Chain Coordination: Clear and uniform coding enhances communication between suppliers, manufacturers, and customers throughout Europe and internationally.
• System Design: Engineers can incorporate consistent hose assembly references in documentation and design software, improving system integration reliability.

Related Standards

To fully implement SIST EN 3086:2019, it is advisable to consider other related aerospace and hose assembly standards, such as:

• EN Aerospace Product Standards (e.g., EN XXXX series): These define coupling types and measurement datum points referenced in SIST EN 3086:2019.
• ISO and IEC Terminological Databases: For standardized technical vocabulary used in aerospace fluid systems.
• ASD-STAN Standards: The Aerospace and Defence Industries Association of Europe’s suite of standards supports interoperability in aerospace components.

Conclusion

SIST EN 3086:2019 is a critical standard for the aerospace industry, enabling a compact and comprehensive 15-digit code system for hose assemblies. Its structured approach to size, length, coupling configuration, orientation, and material coding streamlines component identification across multiple European and global aerospace markets. Organizations adopting this standard benefit from enhanced accuracy, traceability, and operational efficiency in aerospace fluid system management.
