TS 5423 ISO 6107-3

TS 5423 ISO 6107-3 is a terminology standard for water quality. It collects terms and definitions used in specific fields of water quality characterization, helping users apply the same technical language consistently in monitoring, assessment, reporting, and professional communication. The central purpose of the document is conceptual clarity: it aligns the vocabulary used to describe the chemical, physical, biological, and environmental aspects of water quality.

How the vocabulary supports water-quality work

Water-quality work spans many settings, including surface water, groundwater, drinking water, wastewater, and environmental surveillance. In such a broad field, the same concept can easily be described in different ways unless terminology is carefully controlled. This part of ISO 6107 brings together definitions for terms used in selected areas of water-quality characterization. As a terminology standard, it is about shared meaning rather than test methods, numerical limits, or mandatory analytical procedures.

Reading the scope of this document correctly

• It is a terms-and-definitions standard, not a testing-method standard.

• It supports consistent naming in water analysis and environmental reporting.
• It helps reduce ambiguity when specialists from different disciplines exchange data.
• This record represents a withdrawn edition, but it remains relevant as a historical terminology reference.
