TS EN ISO 772

TS EN ISO 772 is a vocabulary standard for hydrometric determinations. It organises the technical language used when measuring water-related quantities in rivers, channels, open waterways and similar environments, so that the same concepts are understood consistently across reports, datasets and engineering communication. For a document of this kind, the main value lies in terminological alignment rather than in prescribing a test method.

Why hydrometric terminology matters

Hydrometry deals with measurements of water movement and quantity, with core concepts such as discharge, water level, velocity, cross-section and time. A vocabulary standard does not usually define a new measurement procedure; instead, it establishes how terms and symbols are used within the subject field. That helps engineers, laboratories, operators and data users avoid ambiguity when describing measurements, instrumentation or results.

What this standard covers

• Terms used in the field of hydrometric determinations
• Definitions and descriptive meanings for those terms
• Symbols employed within the subject area
• Terminological consistency across related hydrometric concepts

The document provides the vocabulary and symbol framework associated with TS EN ISO 772 itself. It does not, from the supplied scope, specify a particular experimental method, numerical acceptance limit or performance requirement. In general technical practice, hydrometric terminology supports river gauging, flow monitoring, flood assessment, canal operation and the interpretation of hydraulic data, where precise wording is essential for traceability and communication between organisations.
