GOST 28352-89 PDF

Full title and description

GOST 28352-89 — "Connecting heads for fire equipment. Types, main parameters and dimensions." The standard specifies types, principal parameters and dimensional requirements for connecting heads (couplings) used on fire hoses and related firefighting equipment for both pressure (discharge) and suction applications.

Abstract

This interstate (GOST) standard defines geometry, nominal sizes, and main operational parameters for hose connecting heads (напорные и всасывающие головки) used to join fire hoses to each other and to fire-fighting appliances. It establishes type designations, dimensional tables and key performance limits intended for manufacture, inspection and use (including export).

General information

• Status: Withdrawn / ceased in the Russian Federation (superseded by a later national standard).
• Publication date: Standard designation year 1989 (approved 29 Nov 1989); entered into force 1 January 1992.
• Publisher: Approved by the State Committee for Standards of the USSR (Gosstandart) as an interstate standard; developed with participation of the Ministry responsible for construction and fire equipment.
• ICS / categories: ICS 13.220.10 (fire‑fighting equipment / fire protection equipment).
• Edition / version: Original designation GOST 28352-89 (approved in 1989, text in force from 1992; later editorial updates/errata noted in historical records).
• Number of pages: Approximately 15 pages (standard document length as published).

Scope

Applies to connecting heads (couplings) intended to connect pressure, suction and pressure‑suction fire hoses to each other and to fire‑fighting equipment. The standard covers constructive types, nominal (passage) sizes, key dimensions, and main parameters such as rated working pressure ranges for typical type‑sizes; it does not prescribe specific detailed constructions beyond the dimensional and functional requirements. The standard was intended for manufacture, interchangeability within the GOST system, and export.

Key topics and requirements

• Definition of coupling types (discharge/pressure heads and suction heads) and type designations (e.g., GR series type‑sizes).
• Dimensional tables listing nominal passages, flange/connection diameters, key lengths and tolerances for each type‑size.
• Specified rated working pressures by type/size (typical values used for design and testing of hose couplings).
• Requirements for interchangeability, marking and basic sealing/gasket interfaces (to ensure compatibility between hoses and appliances made to this standard).
• Normative references and cross‑references to related fire equipment standards (material, testing and environmental/installation requirements referenced elsewhere).

Typical use and users

Used by fire‑fighting equipment manufacturers, hose and coupling producers, shipyards and marine safety equipment suppliers, fire service procurement and maintenance organizations, and export manufacturers aiming to supply equipment into markets that accepted GOST coupling dimensions (countries of the former USSR and some export markets). GOST 28352-89 dimensional forms remain in use for production and replacement parts where legacy compatibility is required.

Related standards

Replaced earlier national standards such as GOST 2217-76 and GOST 12964-80 at the time of its approval; later its application in the Russian Federation was ended and a national successor standard (ГОСТ Р 53279-2009) covers general technical requirements and testing for fire‑fighting connecting heads. The standard is also cited by and cross‑referenced in a range of other fire‑equipment standards (hose branches, suction strainers, cabinets, etc.).

FAQ

Q: What is this standard?

A: GOST 28352-89 is an interstate (GOST) technical standard that defines types, main parameters and dimensional requirements for connecting heads (hose couplings) used on fire‑fighting hoses and related equipment.

Q: What does it cover?

A: It covers classification of coupling types (pressure/discharge and suction), nominal sizes, tabulated dimensions and tolerances, and principal performance parameters (for example rated working pressures associated with particular type‑sizes). It establishes interchangeability and marking requirements needed for manufacture and repair.

Q: Who typically uses it?

A: Manufacturers of fire hoses, couplings and accessories; fire‑fighting appliance makers; procurement and maintenance teams in fire services; marine and offshore equipment suppliers; and companies supplying replacement parts for older systems that were built to GOST dimensions.

Q: Is it current or superseded?

A: It has been superseded for application in the Russian Federation and was withdrawn from use there (application ceased 1 May 2009); a later national standard (ГОСТ Р 53279-2009) now covers technical requirements for fire connecting heads in Russia. However, the GOST 28352-89 dimensional definitions remain relevant where legacy equipment or export compatibility is required.

Q: Is it part of a series?

A: It is part of the set of GOST / GOST‑R standards addressing fire‑fighting equipment (hoses, branches, strainers, couplings and related fittings) and is cross‑referenced by multiple related standards that govern materials, testing and installation.

Q: What are the key keywords?

A: Connecting heads; fire hose coupling; coupling dimensions; GOST 28352-89; pressure head; suction head; firefighting fittings; interchangeability.
