ISO 8153-1:2009

Overview

ISO 8153-1:2009 - Aerospace fluid systems and components - Vocabulary - Part 1: Hose assemblies is an international vocabulary standard that defines terms used for all types of hose assemblies in aerospace fluid systems. Published in 2009 by ISO/TC 20/SC 10, the standard standardizes naming and definitions for hoses, hose fittings, construction layers, dimensions, protection, conductivity and common defects. It clarifies general terminology and how supplementary terms can refine meaning for specific designs, materials or applications.

Key Topics

The standard organizes vocabulary into focused categories. Major topics include:

• General terms - definitions such as “hose”, “hose assembly” and “hose line”.
• Materials - terminology for inner tube materials (e.g., elastomeric hose, PTFE hose, plastic hose, metal hose).
• Design and construction - terms for reinforcement types (braid, spiral, helix, wrap), hose wall layers (inner tube, intermediate layer, cover) and specific constructions (e.g., convoluted PTFE hose).
• Applications and configurations - terms like sleeve hose, preformed hose, suction hose and distinctions between separable, swaged/crimped, clamp and socketless fittings.
• Fittings and components - vocabulary for hose fittings, nipples/inserts, sockets, swivel nuts, elbows, banjo and flange ends, plus hose-side vs connecting-end configuration.
• Dimensions and geometry - linear and angular terms: hose assembly length, free length, bend radius, angle of elbow, orientation and twist.
• Conductivity and protection - definitions for electric conductivity, conductors, antistatic rubber, protective sleeves, anti-chafe sleeves and firesleeves.
• Defects - standardized terms for abrasion, broken wires, chafing, and classifications (minor vs major).

Applications and Users

ISO 8153-1 is primarily used in the aerospace sector to ensure consistent terminology across:

• Design and engineering teams specifying hose assemblies and fittings
• Procurement and suppliers preparing technical datasheets and parts lists
• Maintenance, inspection and quality assurance personnel documenting defects and repairs
• Technical authors, trainers and regulatory bodies producing manuals, instructions and standards references

Using a common vocabulary reduces misinterpretation in engineering drawings, procurement documents, installation instructions and maintenance reports.

• ISO 7313 - referenced for convoluted PTFE hose construction
• ISO 8153 - Part 2 (Fittings) noted as under preparation in the foreword
