TS 4516

TS 4516 is a terminology standard for water quality, bringing together definitions for terms used in water sampling, water analysis, types of water and water treatment. Vocabulary standards such as this one create a common technical language, helping to avoid ambiguity when the same term is used in laboratory work, environmental monitoring and engineering practice.

Why water quality vocabulary matters

Water quality work covers different water contexts, including surface water, groundwater, drinking water, process water and wastewater, and each context can require different measurement and interpretation approaches. A terminology standard helps ensure that names used for sampling, analysis, treatment and classification are understood consistently, which supports clearer communication and more comparable data across technical teams and documents.

Technical coverage of this part

According to the supplied scope, this standard covers terms related to taking water samples, analysing water, types of water, water purification and other water-related definitions. That makes it a vocabulary document rather than a test method or performance specification: its purpose is to organise concepts and their meanings, not to prescribe laboratory procedures or acceptance limits. Its main value lies in clarifying the boundaries between closely related technical terms.

Listed as equivalent to ISO 6107-2:1981, TS 4516 is aligned with an international water quality terminology framework. Although this edition is withdrawn, it remains useful as a reference for interpreting terminology in older water quality documents and historical technical records.
