ISO 5660 Heat Release Rate Testing of Polymeric Materials
The ISO 5660 series of standards defines the testing procedures for heat release rate (HRR) and other fire-related properties of polymeric materials. This service is particularly critical in ensuring that materials used in railway and transportation applications meet stringent safety requirements, especially when it comes to minimizing the risk of fire spread.
Heat Release Rate Testing involves exposing a material specimen to controlled heat and measuring its response—specifically, how much heat is released during combustion. This parameter provides insights into the flammability characteristics of materials under realistic conditions encountered in real-world applications such as railway vehicles, aircraft interiors, and other transportation systems.
The testing process follows ISO 5660-1 for HRR determination using a Cone Calorimeter, which is designed to simulate fire conditions that materials might encounter. The test apparatus includes a calorimeter chamber where the specimen is ignited at one end by an ignition source. The heat released from the burning material is measured as a function of time.
The results provide crucial data on the heat release rate and mass loss rate, which are key indicators for assessing the fire hazard potential of polymeric materials. These parameters help determine whether a material can be used in high-risk areas within transportation systems without posing an undue risk to passengers or crew.
For our railway and transportation clients, accurate HRR testing is essential not only for compliance with international standards like ISO 5660 but also for ensuring the reliability of materials that contribute significantly to fire safety. By using this service, you can ensure your products are robust against fire risks, thereby enhancing overall passenger safety.

Scope and Methodology
The scope of ISO 5660 Heat Release Rate Testing includes the determination of heat release rate, mass loss rate, and other fire-related properties for polymeric materials. The methodology involves precise preparation of specimens according to ISO standards, careful calibration of testing equipment, and consistent application of ignition sources.
- Specimen Preparation: Specimens are cut from the material in accordance with specified dimensions and tolerances as outlined in ISO 5660-1.
- Calibration: The calorimeter is calibrated to ensure accurate measurements of heat release and mass loss rates.
- Ignition Source: A standard ignition source is used, which ignites the specimen at a controlled rate, simulating real-world fire conditions.
The testing process itself involves placing the specimen into the calorimeter chamber, initiating combustion with the ignition source, and recording data on heat release and mass loss as functions of time. This data is then analyzed to determine compliance with relevant safety standards.
Industry Applications
- Railway Vehicle Interiors: Ensuring that materials used in seating, partitions, and other interior components are fire-resistant to protect passengers during emergencies.
- Aircraft Cabins: Evaluating the flammability of cabin materials to prevent rapid fire spread during emergencies. This is crucial for maintaining safety standards as outlined by international aviation authorities.
- Public Transport Seats and Covers: Maintaining safety in crowded public transport vehicles by using non-combustible or low-flammability materials, which can significantly reduce the risk of fire-related incidents.
The data obtained from ISO 5660 testing is critical for manufacturers to comply with international standards and regulations. This service ensures that your products not only meet these requirements but also contribute to enhancing overall safety in railway and transportation systems.
Environmental and Sustainability Contributions
- Reduces Fire Risk: By ensuring materials are non-combustible or have low flammability, ISO 5660 testing helps in reducing the risk of fire-related incidents.
- Promotes Safety Standards: Compliance with ISO standards ensures that products meet stringent safety requirements, contributing to safer transportation environments.
The use of non-combustible materials not only enhances fire safety but also supports sustainability efforts by minimizing the environmental impact associated with fire incidents. By adopting this service, you contribute to a more sustainable and safer future for railway and transportation sectors.
