TS ISO 6426-1

TS ISO 6426-1 is a terminology standard that brings together the meanings of principal technical and scientific terms used in horology. In watch and clock work, clear communication depends on being able to describe functions, measuring concepts, and mechanisms in a consistent way; this standard supports that shared language.

How horological terms are used in technical practice

Horology is the study of devices that measure and display time. In this field, the link between a term and its definition matters: a concept is not just named, it is distinguished from related concepts by a precise technical explanation. Vocabulary standards like this one reduce ambiguity in design, manufacturing, servicing, training, and technical documentation. In general technical context, consistent naming across mechanical, quartz, and other timekeeping systems makes it easier to separate components, operating principles, and measurement-related ideas.

What this standard covers in general

This standard defines the principal technical and scientific terms used in the horological industry. Its focus is therefore on terminology rather than on product performance. As a vocabulary reference, it helps establish a common language for mechanisms, regulating elements, measurement expressions, and scientific naming used in watchmaking and clockmaking. Clear terminology is especially important where accuracy, time base, mechanical transmission, and display system are discussed, because these concepts can otherwise be confused.

• Defines principal technical and scientific terms used in horology and watchmaking.
• Focuses on concept definitions rather than product testing or performance limits.
• Supports consistent language in design, production, servicing, training, and documentation.
• Helps distinguish mechanisms, operating principles, and measurement-related concepts.
