ISO 5843-1:1985

Overview

ISO 5843-1:1985 - "Aerospace construction - List of equivalent terms - Part 1: Aerospace electrical equipment" is a multilingual vocabulary standard prepared by ISO/TC 20 (Aircraft and space vehicles). It establishes a harmonized list of electrical equipment terms used in aerospace construction, given in English (alphabetical order) with equivalent terms in French, Russian and German. The German equivalents were included at the request of ISO/TC 20; however, only the three official ISO languages (English, French, Russian) are considered the formal ISO terms.

Key topics

The document focuses on consistent terminology for aerospace electrical equipment and contains:

• Multilingual equivalents (English → French, Russian, German) for electrical components and functions.
• An alphabetical English list as the primary reference.
• Alphabetical indexes in French, Russian and German for reverse lookup.
• Representative term groups included in the extract: actuator, alternator, battery, bus (bar), breaker, cable, connector, contactor, circuit, generator, charger, annunciator, etc.
• Scope limited to vocabulary: it does not define performance specifications or design requirements, but supports consistent naming and documentation.

Practical applications

ISO 5843-1:1985 is a practical tool for ensuring clear communication across international aerospace projects:

• Harmonizes terminology in technical manuals, drawings, wiring diagrams and specifications for aircraft electrical equipment.
• Supports translation accuracy between English, French, Russian and German in regulatory filings and contracts.
• Facilitates consistent parts procurement, configuration management and supply‑chain communications across multinational teams.
• Useful for maintenance, repair and overhaul (MRO) documentation where precise naming reduces errors.
• Helps training and competency materials by providing standardized vocabulary for instructors and technical writers.

Who should use this standard

• Aircraft and aerospace electrical engineers
• Technical writers and illustrators preparing manuals and wiring diagrams
• Translators and terminology managers working with aerospace documentation
• Suppliers, manufacturers and quality managers in the aerospace supply chain
• Regulatory bodies and certification authorities reviewing multilingual documentation
