GOST R 53961-2010 PDF

Full title and description

GOST R 53961-2010 — Fire-fighting equipment. Underground fire hydrants. General technical requirements. Test methods. The standard specifies general technical requirements, design and construction features, performance and reliability indicators, safety and environmental requirements, acceptance and test methods for underground (pit) fire hydrants used to take water from a water-supply network for firefighting.

Abstract

National standard of the Russian Federation that sets mandatory technical characteristics and test procedures for underground fire hydrants (heights, nominal diameters, valve stroke, working pressure, hydraulic resistance, materials, durability and acceptance tests). It was approved for voluntary application as a GOST R standard and introduced into force on 1 July 2011. The document consolidates design, performance and test requirements intended to ensure safe and reliable operation of underground fire hydrants in municipal and industrial water-supply systems.

General information

• Status: Approved and introduced 1 July 2011; replaces ГОСТ 8220-85. Some commercial catalogues list older metadata variations (e.g., “withdrawn”) but no authoritative Rosstandart public record of formal withdrawal of ГОСТ Р 53961-2010 was found in the searches performed.
• Publication date: Approved by Rosstandart order 25 November 2010; date of introduction into force 1 July 2011.
• Publisher: Federal Agency on Technical Regulating and Metrology (Rosstandart) — published as a national (GOST R) standard.
• ICS / categories: Related to fire protection and firefighting equipment (typical ICS grouping for fire-fighting equipment is within 13.220 — fire protection; closely related construction/installation categories also apply). Specific national catalogs sometimes index it under fire‑fighting equipment / underground hydrants.
• Edition / version: First edition (designated by the year in the identifier — 2010). Introduced for use 01 July 2011 per Rosstandart order N 522-ст.
• Number of pages: 20 pages (common bibliographic listings and standards resellers list the document as 20 pages).

Scope

Applies to underground (pit-mounted) fire hydrants installed on water-supply networks and mounted on fire stands for use with fire columns/standpipes. The standard covers classification by height and internal passage (DN 100–150), general technical requirements, materials, mechanical and hydraulic characteristics, ergonomic and safety requirements, environmental and durability requirements, rules for acceptance, and specified methods of testing (including pressure tests, hydraulic resistance measurement, operational opening/closing force checks and acceptance tests after manufacture).

Key topics and requirements

• Classification by height (typical range 500 mm to 3500 mm with 250 mm steps) and by internal nominal diameter (DN 100, 125, 150).
• Maximum working pressure: 1.0 MPa (10 kgf/cm²) specified for operation and for pressure tests.
• Valve stroke (travel) requirement: 24–30 mm.
• Operational parameters: specified number of turns for full opening (12–15 turns), limits on spindle axial play (≤ 0.4 mm), and limits on hydraulic resistance depending on DN and height.
• Materials and corrosion resistance: body and internal parts to be from steels, cast irons or alloys meeting listed material standards; sealing rings and elastomers defined by referenced GOSTs (e.g., frost-resistant rubber per GOST 7338 where applicable).
• Reliability and durability targets: full service life and maintenance intervals; normative indicators such as guaranteed service life (documented values), acceptance tests and minimum no-failure cycles for factory testing.
• Safety, ergonomics and environmental requirements: limits on opening/closing forces (not exceeding specified N), climatic categories for manufacture, and restrictions on lubricant leakage during storage/transport.
• Acceptance and test methods: visual inspection, thread checks, pressure/ leak tests, opening/closing force measurement, functional tests of drain devices and dimensional checks as specified in test clauses.

Typical use and users

Used by manufacturers of firefighting hydrants, municipal water utilities, fire departments, procurement and quality engineers, testing laboratories, installers and designers of water-supply and fire-protection systems, and regulators who reference national standards for product specification and conformity assessment. The standard is used to specify production tolerances, acceptance test protocols and installation/maintenance requirements for underground hydrants in urban and industrial infrastructure.

Related standards

The standard references and is intended to be used together with other national standards governing fire columns/standpipes, connecting parts, materials and testing methods — for example: ГОСТ Р 53250 (fire columns / technical conditions), ГОСТ 5525 (connective cast parts / flanges), and it was introduced to replace ГОСТ 8220-85 (Underground fire hydrants — specifications). The document also refers to general materials standards and test-method standards cited in its normative references.

FAQ

Q: What is this standard?

A: A Russian national (GOST R) standard titled "Fire-fighting equipment. Underground fire hydrants. General technical requirements. Test methods" that defines technical, safety and test requirements for underground fire hydrants; approved by Rosstandart order N 522-ст and introduced 1 July 2011.

Q: What does it cover?

A: Design, classification (height and nominal diameter), materials, mechanical and hydraulic performance limits (including working pressure = 1.0 MPa), ergonomic and safety requirements, environmental/durability requirements, acceptance rules and specified test methods for underground fire hydrants.

Q: Who typically uses it?

A: Manufacturers of hydrants, municipal water utilities and fire services, testing laboratories, procurement and quality engineers, system designers and installation/maintenance teams responsible for fire‑fighting water supply infrastructure.

Q: Is it current or superseded?

A: The standard was approved and introduced into force on 1 July 2011 (replacing ГОСТ 8220-85). Commercial and reseller catalogs sometimes carry differing metadata (for example, listed as "withdrawn" in some third‑party catalogs). A Rosstandart approval order establishing ГОСТ Р 53961-2010 as a national standard is available (order N 522-ст, 25 Nov 2010). No definitive Rosstandart public record of subsequent formal withdrawal was located in the searches performed for this summary — if you require the absolute current legal status for procurement or regulatory compliance, verify directly with the official Rosstandart registry or a current national standards subscription service.

Q: Is it part of a series?

A: It is part of a group of fire‑fighting equipment standards (GOST R series for firefighting technology) and is cross‑referenced with related GOSTs for fire columns, materials and test methods; it directly replaced the older ГОСТ 8220-85 for underground hydrants.

Q: What are the key keywords?

A: Underground fire hydrant, fire-fighting equipment, DN 100/125/150, working pressure 1 MPa, valve stroke 24–30 mm, acceptance tests, hydraulic resistance, ГОСТ Р 53961-2010.
