DIN 5510 Preventive Fire Protection in Railway Vehicles

The DIN 5510 standard, published by the German Standardization Institute (DIN), consists of the following sections under the main heading of "Preventive fire protection in railway vehicles":

• DIN 5510-1 Part 1: Protection levels, fire protection measures and certification
• DIN 5510-2 Part 2: Fire behavior and fire side effects of materials and parts - Classification, requirements and test methods
• DIN 5510-4 Part 4: Vehicle design - Safety requirements
• DIN 5510-6 Part 6: Auxiliary measures, emergency brake actuation function - Information systems, fire alarms, fire fighting equipment, safety requirements

In the DIN 5510-1 standard, the principles for rail vehicles covered by the relevant legal regulations are explained. This section contains protection levels, fire protection measures and certification information for rolling stock. This chapter defines fire behavior classes for building materials and presents the requirements and test methods for each class.

In the DIN 5510-2 standard, the combustion behavior of materials and parts, smoke density and falling behavior and the principles for fire classification of railway vehicle material and structure are explained. This section applies to all trains, rolling stock and subways. The requirements in this section are listed as follows:

• Specification for risk-based differentiation
• Compliance with fire protection requirements for materials and components used in the construction of rail vehicles
• Compliance with fire protection requirements for integrity
• Compliance of the structural design of rail vehicles with fire protection regulations according to DIN 5510-4 standard
• Conformity of electrical equipment specifications according to DIN 5510-5 standard
• Conformity of functional characteristics of emergency braking device, information systems, fire alarm systems and fire fighting equipment according to DIN 5510-6 standard
• Proof of eligibility
• surveillance evidence

According to the DIN 5510-2 standard, the test methods applied for the cables used in railway vehicles are as follows:

• DIN EN 60332-1-2 Tests on electrical and fiber optic cables under fire conditions - Part 1-2: Vertical flame propagation test for a single insulated wire or cable Procedure for a 1 kW premixed flame
• DIN EN 50266-2-4 Common test methods for cables in fire conditions - Vertical flame propagation test of vertically mounted bundled wires or cables - Part 2-4: Procedures – Category C
• DIN EN 61034-2 Measurement of smoke density of burning cables under defined conditions - Part 1: Test apparatus
• ISO 5659-2 Plastics - Smoke generation - Part 2: Determination of optical density by single chamber test

In the DIN 5510-4 standard, the principles for rail vehicles covered by the relevant legal regulations are explained. The aims of this section are:

• structural design
• Making swaddling difficult
• Making fire difficult due to technical faults or poor heat dissipation
• Preventing or at least delaying the spread of fire

In the event of a fire in a vehicle, fire protection levels 1 to 3 according to part XNUMX of this standard should be applied to enable occupants to self-rescue. In addition to this standard, the following should be considered when designing vehicles:

• Layout of electrical equipment.
• Execution of room-closure systems.
• Requirements for devices for flammable gases and liquids.

In the DIN 5510-6 standard, the principles for rail vehicles covered by the relevant legal regulations are explained. This chapter covers accompanying measures for preventive fire protection in rail vehicles for emergency braking system, information system, fire alarm systems and fire fighting equipment.
