Full title and description

GOST 33463.6-2016 — "Life support systems on railway rolling stock. Part 6. Methods of hygienic assessment of water supply system" (Russian: «Системы жизнеобеспечения на железнодорожном подвижном составе. Часть 6. Методы гигиенической оценки системы водоснабжения»). Стандарт устанавливает методы отбора проб и лабораторной оценки качества воды в системах хозяйственно-питьевого водоснабжения на локомотивах, моторвагонном и специальном подвижном составе с целью гигиенической оценки по санитарно-химическим и санитарно‑микробиологическим показателям.

Abstract

This standard specifies procedures for preparing rolling-stock water-supply systems for testing, locations and numbers of sampling points, sampling, storage and transport of samples, and laboratory methods (sanitary-microbiological and sanitary-chemical) used to evaluate water quality and compare it with the supplied (source) water. It includes mandatory test methods (e.g., membrane filtration, oxidase testing, indicator organisms) and requirements for reporting and safety during testing.

Scope

The standard applies to locomotives, motor‑wagon rolling stock and special railway rolling stock equipped with household/drinking water supply systems. It establishes hygienic assessment methods for those onboard water-supply systems by comparing the quality of water taken from system sampling points with the quality of the source (replenishment) water using defined sanitary‑microbiological and sanitary‑chemical indicators. The standard covers sampling point selection, system preparation (disinfection, flushing, filling), sampling procedures, laboratory methods, evaluation against hygienic norms, test reporting and safety requirements for personnel.

Key topics and requirements

• Definition of sampling points (all consumer taps, inlet/source point, before/after treatment units) and sample volumes required for specified analyses.
• Requirements for system preparation prior to sampling: disinfection, flushing and filling procedures.
• Sanitary‑microbiological methods: membrane filtration, determination of indicator organisms (coliforms, coli‑phages), oxidase tests, procedures for legionella detection and other microbiological assays.
• Sanitary‑chemical analyses: parameters and laboratory methods to quantify chemical indicators and compare with hygienic standards for drinking water.
• Evaluation principle: compare system water results with source water and with applicable hygienic norms (national drinking‑water limits); identify deterioration caused by materials, biofouling or treatment failures.
• Reporting: required contents of test protocol (sampling scheme, methods used, measured values, conformity assessment, organization and date).
• Occupational safety: competency and safety requirements for personnel performing sampling and tests (training, PPE, procedures per occupational-safety standards).

Typical use and users

Primary users include railway vehicle manufacturers and designers, rolling‑stock operators, maintenance and technical inspection teams, public‑health and sanitary inspection authorities, independent testing and certification laboratories, and organizations responsible for onboard water system installation, maintenance and commissioning. The standard is used when validating new or modified onboard water systems, performing periodic hygienic checks, investigating water‑quality incidents, and preparing conformity reports.

Related standards

Part of the GOST 33463 series (life‑support systems on railway rolling stock). The standard references national drinking‑water hygienic regulations (e.g., applicable SanPiN requirements within the Russian Federation) and other normative methods for microbiological and chemical testing (examples include GOSTs addressing indicator organisms and specific test methods). Implementing bodies should consult the companion parts of GOST 33463 and referenced sanitary regulations for full compliance.
