ISO 1069:1973

Overview

ISO 1069:1973 - "Magnetic compasses and binnacles for sea navigation - Vocabulary" is an International Standard that provides the authoritative bilingual (English/French) terminology for magnetic compasses, binnacles and related magnetic concepts used in marine navigation. Published in 1973 (first edition, 36 pages), it replaces ISO Recommendation R 1069‑1969 and was prepared by ISO Technical Committee TC 8 (Shipbuilding). An annex supplies equivalent terms in eight additional languages (published under the responsibility of the respective ISO member bodies).

Key topics

The standard defines and clarifies terminology across these major areas:

• Scope and field of application - purpose and bilingual status of ISO terms.
• Magnetism - theoretical definitions (magnetic poles, permanent/sub‑permanent/transient magnetism, magnetic receptivity).
• Magnetic properties - permeability, coercivity, remanence, residual magnetism.
• Earth’s magnetism - local magnetic force components (H and Z), dip (inclination), variation (declination), lines of magnetic force.
• Magnetic materials - classification and behavior of hard, intermediate and soft iron, and non‑magnetic materials.
• Compass position characteristics - directive force at the compass position, mean directive force and related concepts.
• The mariner’s compass - general and specific compass types and definitions (magnetic, liquid, dry/dry‑card, hemispherical, aperiodic, steering, stand‑by, emergency, overhead, periscopic, reflector compasses).
• Binnacle and azimuth devices - vocabulary relating to binnacles and azimuth‑reading devices, plus siting of the compass on the ship.
• Annex - multilingual term translations.

Practical applications

ISO 1069:1973 is a reference vocabulary used to ensure consistent technical language and avoid misunderstandings in:

• Shipbuilding and marine equipment design documentation
• Naval architecture and vessel outfitting (compass mounting and binnacle specification)
• Manufacturer datasheets, installation manuals and product labeling for compasses and binnacles
• Maritime regulations, survey reports and classification society records
• Technical translation, standards harmonization and education/training in marine navigation and compass servicing

Who should use it

• Shipbuilders, naval architects and marine engineers
• Compass and binnacle manufacturers and distributors
• Maritime regulators, classification societies and flag administrations
• Marine surveyors, navigational equipment installers and repair technicians
• Technical writers and translators working on marine navigation documentation

Related standards

ISO 1069:1973 stems from ISO/TC 8 (Shipbuilding) work and replaces ISO/R 1069‑1969. For implementation or compliance, consult current ISO catalogues or TC 8 publications to identify any later revisions or complementary navigation standards.
