GOST R 51115-97 PDF

Full title and description

GOST R 51115-97 — "Техника пожарная. Стволы пожарные лафетные комбинированные. Общие технические требования. Методы испытаний" (Fire-fighting equipment. Fire turntable combined monitors. General technical requirements. Test methods). The standard sets mandatory technical, safety and test requirements for combined (water/foam) fire monitors intended for installation on fire appliances, vessels and fixed fire-fighting installations.

Abstract

This national standard defines classification, constructional and performance requirements, environmental and mechanical operating limits, corrosion-protection and surface treatment requirements, acceptance and periodic test procedures, measurement methods for flow and throw distance, and documentation requirements for fire turntable combined monitors. The standard was issued as GOST R 51115-97 and later withdrawn and replaced by a more recent national standard.

• ICS / categories: ICS 13.220.10 (Fire-fighting equipment); category: Fire safety equipment.

• Number of pages: 14 (typical published version).

Scope

The standard applies to combined (water/foam) fire monitors — stationary or vehicle-mounted turntable (lafetnye) nozzles — and establishes their general technical requirements, allowable operational ranges (mechanical travel, working pressure, environmental temperature), performance characteristics (discharge rates, throw distances), materials and coatings, test methods for type and acceptance testing, and requirements for marking and accompanying documentation. It is intended for use where national rules reference GOST R technical requirements for fire monitors.

Key topics and requirements

• Definitions and classification of combined/turntable fire monitors (types and intended use).
• General constructional requirements, materials and corrosion-protection (references to related GOSTs on coatings and anti-corrosion treatment).
• Performance parameters: nominal discharge (flow) and throw distance measured at specified test pressures (typical reference pressure 0.8 MPa).
• Mechanical limits and kinematics: vertical and horizontal travel angles and minimum movement ranges (examples: vertical movement ranges with specified up/down angles for universal and lafet types).
• Environmental and operational limits: guaranteed operation across a specified temperature range (commonly −40 °C to +40 °C) and resistance to vibration and mechanical shocks.
• Acceptance, type and periodic test procedures: sampling rules, frequency of periodic testing depending on production volume, and requirements for repeating tests after nonconformities.
• Test methods for measuring flow, throw distance, foam generation (for foam-capable monitors) and leak/pressure tests.
• Marking, documentation and manufacturer’s technical data: required information on nameplate, technical passport, and user/maintenance instructions.

Typical use and users

Primary users are manufacturers and designers of fire-fighting monitors and related equipment, testing and certification laboratories, procurement specialists in fire departments and industrial facilities, regulatory and inspection bodies responsible for fire safety compliance, and organisations that install monitors on fire vehicles, vessels and fixed systems.

Related standards

Standards and normative references commonly associated with GOST R 51115-97 include national GOSTs on corrosion protection and coatings (for example GOST 9.014‑78, GOST 9.032‑74, GOST 9.306‑85), safety testing standards (for example GOST 12.2.033‑78), and other fire-equipment standards. GOST R 51115-97 has been superseded in the national system by a later standard addressing modern requirements for fire monitors (notably GOST 34778-2021 or the most recent national technical standard covering fire monitors), which should be consulted for current mandatory requirements.

FAQ

Q: What is this standard?

A: GOST R 51115-97 is a Russian national standard that specified general technical requirements and test methods for combined turntable (lafet) fire monitors (water/foam fire nozzles).

Q: What does it cover?

A: It covers classification, construction and material requirements, performance characteristics (flow and throw), environmental and mechanical operating limits, corrosion-protection and surface-treatment rules, type/acceptance/periodic test methods, marking and documentation requirements.

Q: Who typically uses it?

A: Manufacturers and designers of fire monitors, testing and certification laboratories, fire service procurement and maintenance teams, and regulatory inspectors apply the standard when specifying, testing or certifying fire monitors.

Q: Is it current or superseded?

A: GOST R 51115-97 has been withdrawn/cancelled and replaced by a later national standard. The standard was implemented in 1999 and formally superseded in national practice (cancelled on 01 July 2024); users should adopt the successor standard (for example GOST 34778-2021 or the currently applicable fire monitor standard) for up-to-date mandatory requirements.

Q: Is it part of a series?

A: Yes. It is part of the body of GOST/GOST R standards addressing fire-fighting equipment and fire safety. It is related to other GOSTs that set requirements and test methods for fire nozzles, foam systems and coatings; adjacent standards cover different monitor types, foam systems and general fire-fighting apparatus requirements.

Q: What are the key keywords?

A: Fire monitor, turntable monitor, lafet nozzle, combined monitor, water/foam nozzle, test methods, flow, throw distance, corrosion protection, GOST R 51115-97.
