GOST R 50969-96 PDF

Full title and description

GOST R 50969-96 — "Automatic gas fire extinguishing systems. General technical requirements. Test methods". The standard establishes general technical requirements, safety and performance criteria, and test methods for centralized and modular automatic gas fire‑extinguishing installations (including methods for evaluating newly developed extinguishing agents, equipment and materials).

Abstract

This national Russian standard (GOST R) defines design and operational requirements, commissioning and periodic test procedures, measurement and instrumentation accuracy rules, and performance acceptance criteria for volume gas fire‑extinguishing systems. It is intended to be used by designers, manufacturers, testing laboratories and authorities to verify that automatic gas fire suppression installations achieve required extinguishing concentrations and reliable operation under specified conditions.

Scope

The standard applies to centralized and modular automatic volume gas fire‑extinguishing installations and sets out mandatory and recommended requirements for their design, component arrangement, safety measures, commissioning, and methods of laboratory and field testing. Methods are provided for cold (no‑fire) tests and live (fire) tests, including procedures to verify achievement of required extinguishing concentrations, time to extinguish model fire sources, and absence of re‑ignition. The methods are intended primarily for installations using newly developed agents, equipment or materials but may be applied more broadly during design, testing and acceptance.

Key topics and requirements

• Definitions and terminology for gas extinguishing agents and installations (the amendment modernized some terminology, e.g., ГОС → ГОТВ).
• General technical requirements for installation composition, placement of elements, and safety devices.
• Test methods: cold (concentration measurement) and fire tests (model fire sources), with acceptance criteria (e.g., attainment of normative extinguishing concentration within specified time — commonly referenced 5 minutes to achieve concentration; no re‑ignition interval specified and adjusted by amendment).
• Commissioning and periodic testing requirements, including comprehensive acceptance tests and guidance that certain comprehensive checks be repeated during operation (amendment indicates periodic comprehensive tests at least once every 5 years in typical practice).
• Measurement and instrumentation accuracy: rules for accounting measurement uncertainty (example: relative error for time parameters not to exceed 5%).
• Functional checks of control and actuation systems (pressure control, triggering, alarm and silencing circuits); example test actions include simulated pressure drops (e.g., 0.05 MPa in trigger lines and 0.2 MPa in supply cylinders) to verify alarms and interlocks.
• Requirements for documentation, test reporting and acceptance protocols.

Typical use and users

Used by fire‑protection engineers, system designers, manufacturers of gas fire‑extinguishing modules and components, testing laboratories, commissioning and maintenance organizations, and regulatory or inspection authorities responsible for approving and supervising installation and performance of automatic gas systems. It is referenced during design, type testing, factory and on‑site acceptance testing, and periodic inspection.
