TS 5798

TS 5798 is a vocabulary standard that brings together the basic and general terms used in metrology. In the science of measurement, a shared technical language is essential for describing what is being measured, how a result is expressed, and which concepts support the interpretation of that result. This standard focuses on consistent use of foundational metrology terms so that laboratories, industries, and technical documents can rely on the same conceptual meanings.

How metrology terminology is organised

In general technical use, metrology terminology covers distinctions such as measurement, measurand, unit, accuracy, uncertainty, calibration, and traceability. A vocabulary standard of this kind helps keep those concepts separate and reduces ambiguity in reports, quality systems, test documentation, and training materials. Its purpose is conceptual: it defines the language of measurement rather than prescribing a measurement method or performance requirement.

Why shared definitions matter

• Supports consistent use of the same measurement concept across different fields.
• Reduces confusion caused by inconsistent or overlapping terminology.
• Improves clarity in calibration, testing, inspection, and quality documentation.
• Helps align national terminology with established international metrology usage.

TS 5798 is based on VIM 1993, the International Vocabulary of basic and general terms in metrology. As such, it serves as a conceptual reference for core metrology terms rather than a document that sets out a testing procedure or numerical limit. For professionals working with measurement, it provides a common linguistic framework that helps connect related standards and technical documents.
