SP 485.1311500.2020 PDF

Full title and description

SP 485.1311500.2020 — "Systems of fire protection. Automatic fire‑extinguishing installations. Design rules and regulations" (original Russian title: «Системы противопожарной защиты. Установки пожаротушения автоматические. Нормы и правила проектирования»). The document defines technical requirements, design methods and verification procedures for automatic fire‑extinguishing systems (water, foam, gas, powder and fine‑spray installations) for buildings, structures and technological units.

Abstract

SP 485.1311500.2020 sets out normative requirements for classification, hydraulic design, equipment selection, piping, controls, integration with fire‑alarm systems, testing, commissioning and maintenance of automatic fire‑extinguishing installations. It replaces earlier rules (including provisions of older national documents) and is intended to harmonize design practice across building types while specifying exclusions and special cases where separate rules apply. The standard has been subject to formal amendments addressing methodical details and test procedures.

• Number of pages: Approximately 105 pages (electronic/print editions reported).

Scope

The standard applies to the design, calculation and arrangement of automatic fire‑extinguishing installations for buildings, structures and technological units. It covers water‑based systems (sprinkler, deluge/drencher, spray and foam‑water systems), gas and powder installations, fine‑spray technologies and their interfaces with fire‑detection and control systems. The scope excludes certain specialised outdoor installations and some highly specific storage or process installations that are regulated by dedicated rules (for example, some high‑rack warehouses, bulk hydrocarbon tank farms and LPG reservoirs are treated by other normative acts or additional clauses). The standard also introduces methods and requirements for hydraulic calculation, equipment selection, piping practice, marking and commissioning tests.

Key topics and requirements

• Classification of automatic fire‑extinguishing installations by type (sprinkler, deluge/drencher, volumetric, foam, gas, powder, fine‑spray) and by operational mode.
• Hydraulic calculation methods and required design flows/intensities for various room groups and hazards (including requirement for individual hydraulic calculations in many cases).
• Requirements for sources of supply and pressure (fire pumps, reservoirs, redundant/pneumatic pressure sources for air‑filled systems).
• Piping, materials, installation practice, marking/paint of exposed pipes and identification signs, and rules to prevent unauthorized connections to AUP pipelines.
• Integration and coordination with fire‑alarm systems and automation (start/stop logic, alarms, interlocks and documentation requirements).
• Type‑specific provisions for foam systems (foam concentrate handling and application rates), gas systems (concentrations and safety interfaces), and powder systems (limitations for occupied spaces).
• Commissioning, periodic testing, maintenance, and documentation required for acceptance by supervisory authorities. Amendment tracks add/clarify test methods (including for fine‑spray systems).

Typical use and users

Primary users are fire‑safety engineers, design institutes, HVAC and building services engineers, system integrators, installers of automatic extinguishing systems, building code authorities and inspection bodies (including MChS regional offices). The standard is used during project design, equipment specification, installation supervision, commissioning and regulatory acceptance of automatic fire‑extinguishing systems. It is also referenced in technical audits and when adapting foreign equipment to meet Russian regulatory requirements.

Related standards

SP 485 is closely associated with other national rules in the SP series, notably SP 484.1311500.2020 (fire detection and automation) and SP 486.1311500.2020 (list of objects requiring automatic extinguishing and fire alarm). It replaces/updates parts of earlier documents such as SP 5.13130.2009 and must be used alongside applicable GOSTs and local regulatory orders when preparing design documentation.

FAQ

Q: What is this standard?

A: SP 485.1311500.2020 is the Russian set of rules for design and engineering of automatic fire‑extinguishing installations, covering water, foam, gas, powder and fine‑spray systems and associated equipment and procedures.

Q: What does it cover?

A: It covers classification of systems, hydraulic design and calculation, supply and pumping requirements, piping and materials, system controls and interlocks, marking and painting of pipelines, commissioning tests, maintenance and documentation — plus methodical provisions introduced by later amendments (including testing methods for some technologies).

Q: Who typically uses it?

A: Fire‑safety and building services designers, installers and integrators of extinguishing systems, regulatory authorities (MChS/VNIIPO), and facility owners/operators requiring compliance for construction permits and acceptance.

Q: Is it current or superseded?

A: The base SP 485 text became effective 1 March 2021. It has since received formal Amendment No.1 (approved by MChS Dec 15, 2025) which entered into force 1 January 2026; the standard is current when used together with approved amendments. Always verify whether later amendments or consolidated texts have been published.

Q: Is it part of a series?

A: Yes — SP 485 is part of the SP (Svod pravil) series on fire protection and is intended to be used alongside related SP documents (for example SP 484 on fire alarm/automation and SP 486 on objects requiring automatic extinguishing).

Q: What are the key keywords?

A: automatic fire‑extinguishing, sprinkler, hydraulic calculation, foam, gas suppression, powder suppression, fine‑spray, fire pumps, MChS, commissioning, SP 485.1311500.2020.
