Buy Wedge INTUF20 best quality smoke free fire resistant Intumescent fire seal strips for Railways applications meeting BS EN 45545-2:2013+A1:2015 fire safety standards. Intumescent fire seal strips  are a crucial component in ensuring the fire safety of railway vehicles. These strips are designed to expand when exposed to high temperatures, thereby sealing gaps and preventing the spread of fire and smoke. For railway applications, these products must meet stringent fire safety standards, such as BS EN 45545-2:2013+A1:2015.
 
Key Properties of Intumescent Fire Seal Strips
Thermal Expansion:
Expand significantly when exposed to heat, sealing gaps around doors, windows, and service penetrations.
Durability:
Designed for long-lasting performance under normal operating conditions and during fire exposure.
Adhesion:
Strong adhesion to various materials used in railway vehicle construction, ensuring a secure seal.
Flexibility:
Able to accommodate the vibrations and movements typical in railway operations.
Compliance:
Meet or exceed the requirements of BS EN 45545-2:2013+A1:2015 for fire safety.
 
Standards and Test Methods
BS EN 45545-2:2013+A1:2015 outlines the requirements for the fire behavior of materials and components used in railway vehicles. The relevant test methods for intumescent fire seal strips include:
T10.01:
Objective: Determine the reaction to fire of materials.
Procedure: Evaluate the material’s ability to resist ignition and limit flame spread under controlled conditions.
T10.02:
Objective: Assess the material’s contribution to fire growth.
Procedure: Measure the heat release rate and smoke production when the material is exposed to a flame.
T10.04:
Objective: Evaluate the material’s resistance to radiant heat.
Procedure: Assess how the material behaves when subjected to a radiant heat source, focusing on the ability to prevent fire penetration.
 
Applications in Railway Vehicles
Door Seals:
Intumescent strips around doors to prevent fire and smoke from entering passenger compartments.
Partition Seals:
Seals in partitions between different compartments to restrict fire and smoke spread within the vehicle.
Service Penetrations:
Seals around pipes, cables, and ducts passing through fire-rated partitions.
Window Seals:
Seals around windows to maintain integrity during a fire.
Intumescent fire seal strips for control panels 
Control panels in railway vehicles require special attention to fire safety due to the concentration of electrical components and the potential for fire hazards.
 
Intumescent fire seal strips are essential for maintaining the fire safety of railway vehicles. They provide critical protection by sealing gaps and preventing the spread of fire and smoke. By using high-quality, compliant products and following proper installation and maintenance practices, railway operators can ensure effective fire protection and meet stringent safety standards.
