NPB 109-96 PDF

Full title and description

NPB 109-96 — «Вагоны метрополитена. Требования пожарной безопасности» (translated: Underground cars / Metro rolling stock — Requirements for fire safety). The document sets mandatory fire-safety requirements for design, construction, reconstruction, major repair and operation of metro cars and related on‑carriage systems.

Abstract

NPB 109-96 is a regulatory technical norm issued for metro rolling stock that defines requirements for materials, interior finishes, fire load limits, sealing and structural details, fire detection and alarm systems, means of fire suppression, evacuation arrangements and test methods used to verify compliance. It was adopted to reduce passenger and personnel risk and to limit material losses from onboard fires.

General information

• Status: Active / in force (ДЕЙСТВУЕТ).
• Publication date: Introduced by order in 1996 and brought into effect 01 January 1997 (with some clauses phased in from 01 January 1998).
• Publisher: Approved and issued under the authority of the state fire‑safety/regulatory bodies of the Russian Federation (documents reference GUGPS / Main State Fire Inspectorate / МВД structures as the approving authority).
• ICS / categories: Fire protection / protection from fire; transport / rolling stock; building and construction safety (classification entries and ISO/ICS classifiers link NPB 109-96 to fire‑safety and transport categories).
• Edition / version: Original designation NPB 109-96 (1996/1997 edition); later commercial compilations and amended reprints are available with editorial updates.
• Number of pages: Commercial copies and databases report varying page counts (commonly shown as 11–26 pages depending on publisher format and translation/annexes).

Scope

Applies to metro/underground passenger cars during design, manufacture, reconstruction (modernization), major repair and normal operation. The norm is mandatory for organisations and persons responsible for rolling stock design, manufacture, overhaul and operation; it also restricts use of more flammable materials during repairs and specifies that older cars remain subject to their original technical documentation unless modernized to comply with NPB 109-96.

Key topics and requirements

• Classification of materials for interior finishes by fire hazard and required test methods for flammability and smoke generation.
• Limits on allowable fire load (examples and clauses reference numerical limits such as the commonly cited 35 kg/m² for certain items), and methods for calculating reduced (equivalent) fire load.
• Requirements for sealing of doors and windows, wall linings, seat upholstery and other furnishings to limit ignition and flame spread.
• Minimum requirements for on‑board fire detection, alarm and communication systems, portable and fixed fire‑fighting equipment, and placement of extinguishers.
• Specifications for electrical equipment and wiring routing to reduce ignition sources, and maintenance/inspection regimes to preserve fire safety during operation.
• Evacuation provisions: marking, lighting, door operation and procedures to ensure safe passenger egress under fire conditions.
• Transitional provisions and restrictions on material substitutions during unscheduled repairs to avoid reduced fire safety.

Typical use and users

Used by rolling stock designers and manufacturers, metro operators and maintainers, railway/metro safety engineers, fire‑safety regulators and certification bodies, procurement teams specifying interior materials, and researchers comparing fire‑safety requirements for passenger vehicles.

Related standards

NPB 109-96 is part of the NPB series of Russian fire‑safety norms and is applied alongside federal fire‑safety rules and related GOST standards (for example, references appear to PB 01-93 / Rules of Fire Safety and ГОСТ 12.1.004-91 for fire safety test methods). Other NPB documents and testing standards on fire equipment and materials are typically referenced for detailed test methods and equipment requirements.
