Full title and description

GOST 27065-86 — "Качество вод. Термины и определения" / "Water quality. Terms and definitions". Standard that establishes terminology and definitions for principal concepts used in the field of water quality (does not apply to wastewater/effluents).

Abstract

Defines standardized terms, definitions and equivalents for water‑quality concepts (e.g., water quality, quality classes, criteria, indices, indicators such as turbidity, mineralization, oxygenation, toxicological and biological parameters). Includes an alphabetical index of terms and a table of term equivalents in some foreign languages.

General information

• Status: Listed as introduced in 1987; some public registries list it as "in force" while others show it among documents cancelled/withdrawn on 1 January 2019 — sources conflict and status may depend on the national registry consulted.
• Publication date: Introduced 1 January 1987 (approved by USSR State Committee for Standards 29 October 1986).
• Publisher: Adopted by the State Committee for Standards of the USSR (Gosstandart); later editions/reprints issued by national standards publishers/IPK publishing (reprints recorded).
• ICS / categories: ICS / MKS: 01.040.13; 13.060 (water quality / environmental protection); OKSTU 0017 referenced.
• Edition / version: Original issue designated GOST 27065-86 (approved 1986, in force from 01.01.1987). Subsequent reprints/collections may carry later publication dates but the normative designation remains GOST 27065-86.
• Number of pages: 8 pages (typical published sheet count in public listings).

Scope

Sets standardized terminology and definitions for general water‑quality concepts used in water management, environmental monitoring and related fields. The standard explicitly does not apply to wastewater/effluent terminology. It is intended to harmonize language for monitoring, reporting and regulatory or technical communication about surface, ground and other non‑waste waters.

Key topics and requirements

• Standardized definitions of core water‑quality concepts (e.g., "quality of water", "class of water quality", "criteria of water quality").
• Definitions and descriptions of common indicators and parameters (turbidity, mineralization, oxygen saturation, biochemical and chemical oxygen demand, toxicity, saprobity, etc.).
• Alphabetical index of terms and Annex with term equivalents in several foreign languages for harmonization across member states.
• Clarification of which water types and applications the terminology covers (general water quality, excluding sewage).

Typical use and users

Used by environmental and water‑management authorities, laboratory analysts, standards writers, researchers, consultants, and industries involved in water monitoring, protection and management who need a common terminology for reporting, regulation, and technical documentation. Also referenced in translations and intergovernmental technical exchanges where consistent term equivalents are required.

Related standards

Linked to the CMEA (ST SEV 5184-85) water‑quality terminology on which it is based; commonly used alongside national and sectoral standards for water monitoring, sampling and measurement methods and for water‑quality criteria (other GOST/GOST R standards, ISO water‑quality standards, and regional technical rules).

Keywords

A: It covers definitions of principal water‑quality concepts, descriptions of common indicators and an alphabetical index of terms and term‑equivalents; it is intended for general water quality (explicitly excludes wastewater/effluents).

Q: Who typically uses it?

A: Environmental agencies, laboratories, standards developers, researchers and practitioners in water management and monitoring use it to ensure consistent terminology in reports, regulations and technical documents.

Q: Is it current or superseded?

A: Public sources show mixed status: some registries list GOST 27065-86 as still in force, while at least one compilation lists it among documents cancelled on 1 January 2019. Users should verify current national registry entries or contact the relevant standards body to confirm legal/operative status for their jurisdiction.
