GOST 31952-2012 PDF

Full title and description

GOST 31952-2012 — "Устройства водоочистные. Общие требования к эффективности и методы её определения" (Water‑treatment devices — General requirements for efficiency and methods for its determination). The standard establishes general performance requirements and standardized test methods for water‑treatment devices intended for disinfection/cleaning of drinking‑water supplies and water sources.

Abstract

This intergovernmental standard specifies the scope, required test bench and measurement arrangements, model solutions and test programmes, and evaluation criteria used to determine reduction efficiency of specified contaminants for water‑treatment devices (including post‑treatment/disinfection units) used with centralized and decentralized drinking‑water systems and water sources. It describes cyclic resource testing (0–120 % of declared resource), sampling points and conditions (temperature, pH, total dissolved solids), and documentation requirements for test reports.

Scope

The standard applies to water‑treatment devices intended for polishing (post‑treatment / post‑disinfection) of water from centralized and decentralized drinking‑water supplies, and to devices for treatment/disinfection of source waters (surface and groundwater), provided the device daily treated volume does not exceed 5 m3/day. It excludes devices intended for removal of radioactive contaminants and certain household devices designed for treatment of unknown‑quality surface water that may be microbiologically unsafe. The standard defines which contaminant classes may be the subject of declared efficiency and how those efficiencies are to be verified.

Key topics and requirements

• Definitions and classification of water‑treatment devices covered (polishing / disinfection / source‑water treatment for ≤5 m3/day).
• Requirements for test stands and auxiliary equipment: flow and pressure control, temperature and pH control, sampling provisions, and disinfection/sterilization of apparatus used for challenge tests.
• Use of model (challenge) solutions reproducing contaminant types and levels specified in product technical documentation, including microbiological challenge procedures and safe handling measures.
• Test programme and resource cycling: efficiency measured at 20 %, 50 %, 80 %, 100 % and 120 % of declared resource with prescribed cyclic on/off operation to simulate realistic use.
• Reporting and documentation: required test report contents (device identification, manufacturer, technical parameters, matrices tested, analytical methods, and test conditions).
• Limitations and corrections: notes on expected efficiency reductions under extreme water chemistry (high TDS, temperature, pH) and conditions affecting declared performance.

Typical use and users

Primary users include manufacturers and developers of water‑treatment and disinfection units (for centralized, decentralized and point‑of‑use applications), independent testing and certification laboratories, regulatory authorities and procurement agencies assessing claimed device performance, and water utilities or building services specifying treatment equipment. The standard is used to harmonize test methods and provide reproducible evidence for declared efficiencies.

Related standards

GOST 31952‑2012 operates alongside national sanitary regulations and drinking‑water quality standards (for example, sanitary rules SanPiN series on drinking water quality) and other GOST standards addressing drinking‑water hygiene and testing methods (for example GOST 2874 on drinking water hygienic requirements is commonly referenced in water‑quality work). Users typically consult related sanitary, building and testing standards when applying GOST 31952‑2012.

FAQ

Q: What is this standard?

A: GOST 31952‑2012 is an intergovernmental (GOST) standard that sets general performance requirements and specifies test methods for determining the efficiency of water‑treatment devices used for polishing/disinfection and source‑water treatment.

Q: What does it cover?

A: It covers device scope (devices up to a declared daily volume threshold), required test stand arrangements, model (challenge) solutions and microbiological procedures, a prescribed resource/cycling test programme (efficiency checks at multiple resource points), data reporting, and performance limitations under extreme water conditions. It does not cover devices for removal of radioactive contaminants or certain household devices for unknown‑quality surface water.

Q: Who typically uses it?

A: Manufacturers, conformity assessment and test laboratories, certification bodies, regulators, water utilities, and purchasers specifying or verifying the declared efficiency of water‑treatment and disinfection devices.

Q: Is it current or superseded?

A: The standard was adopted in 2012 and entered into force on January 1, 2014. It is listed as active/in force in national catalogs; editorial updates and amendments have been recorded (references note entries/updates through 2019). Users should confirm any later amendments or replacements in the national standards registry before relying on claims dated after those updates.

Q: Is it part of a series?

A: GOST 31952‑2012 is a standalone intergovernmental standard addressing general requirements and test methods for water‑treatment devices, but it is commonly used in conjunction with other sanitary, drinking‑water and building‑services standards and regulations (SanPiN, other GOSTs on water quality and analytical methods).

Q: What are the key keywords?

A: Water treatment, water‑treatment devices, efficiency, testing methods, challenge tests, disinfection, drinking water, resource testing, sampling, SanPiN.
