GOST R 53278-2009 PDF

Full title and description

GOST R 53278-2009 — Fire equipment. Fire valves. General technical requirements. Test methods. This national standard of the Russian Federation specifies technical requirements, dimensional and material parameters, marking, acceptance rules and test methods for fire shut-off valves used in fire hydrants and internal fire water-supply systems of buildings and structures.

Abstract

GOST R 53278-2009 establishes mandatory characteristics and test procedures for fire shut-off valves (valves that are part of fire hydrant assemblies) intended for installation in internal firefighting water-supply systems. The standard defines nominal diameters, working pressure, hydraulic resistance coefficients, permitted connection angles and basic material and corrosion-resistance requirements, and it includes acceptance and routine test methods and an implementation schedule for previously made designs.

Scope

This standard applies to fire shut-off valves used in fire hydrants and installed in internal fire-fighting water-supply systems of buildings and structures. It covers dimensional parameters (nominal diameters DN 40, 50 and 65), connection thread types and sizes, rated working pressure, hydraulic resistance coefficients, permitted angles between connection ports, material and corrosion-resistance requirements, marking, packaging and required test methods for type and routine inspection. The standard also contains provisions for transition measures for designs produced before its introduction.

Key topics and requirements

• Nominal diameters: DN 40, DN 50 and DN 65 — dimensioning and basic size limits.
• Rated working pressure: minimum nominal pressure PN 1.0 MPa for the valve body.
• Hydraulic resistance coefficients prescribed by diameter (example values: ~8.5, 7.5, 6.5 for DN 40/50/65 respectively).
• Permitted angle between connection ports: from 90° to 135° (special transition rules for valves with larger angles produced before the standard’s introduction).
• Connection thread: cylindrical pipe thread per GOST 6357, class B, with thread sizes matched to DN (e.g., 1½", 2", 2½" for DN 40/50/65 respectively).
• Material and corrosion-resistance: spindle and moving threads to have corrosion resistance not less than specified for brass per relevant GOSTs; body materials to meet at-least cast-iron grades indicated in the standard; allowance for permitted casting surface imperfections within defined limits.
• Operational and acceptance tests: provisions for pressure, tightness, endurance/cycling, hydraulic performance, gland-seal checks at start and at intervals, visual inspection, marking and completeness checks; service life verified by supplied operational documentation.
• Marking, color and packaging requirements and the contents required in the product passport (technical documentation) are specified.

Typical use and users

Manufacturers of fire valves and fire hydrants, product designers and engineers for building fire protection systems, test laboratories and certification bodies, procurement and quality-assurance departments for construction and facility management, and regulatory authorities responsible for fire-safety equipment compliance. The standard is used when designing, producing, testing, accepting and specifying fire shut-off valves for internal firefighting water systems.
