Flame Spread Testing of Polyurethane Foams
The Flame Spread Testing (FST) of polyurethane foams is a critical process in ensuring compliance with fire safety regulations and enhancing product performance. This testing measures the rate at which flames spread over the surface of materials, providing crucial data for assessing their ignition resistance and flame retardant properties.
Polyurethane foam is widely used across various sectors including furniture, automotive interiors, building insulation, and medical devices due to its comfort, durability, and thermal insulating properties. However, when exposed to fire, the potential of polyurethane foams to spread flames can be a concern, especially in environments where they are in direct contact with open flames or heat sources.
The testing process is designed to simulate real-world conditions under which materials may encounter fire hazards. By subjecting samples to controlled flame exposure and measuring how quickly the flames spread across their surfaces, we can determine their resistance levels effectively. This information is invaluable for product developers seeking to improve material performance, as well as quality managers responsible for ensuring compliance with stringent regulatory requirements.
At Eurolab, our state-of-the-art facilities employ advanced instrumentation tailored specifically for flame spread testing of polyurethane foams. Our experts utilize precise methods that adhere strictly to international standards such as ASTM E84-21 and ISO 6947-1:2013. These guidelines provide clear criteria for conducting accurate tests which ensure reliable results.
Our team also provides comprehensive support throughout the entire testing process, from sample preparation through analysis and reporting. We understand that each client has unique needs when it comes to understanding their materials' behavior in fires; therefore, we offer tailored solutions based on your specific requirements. Our goal is not only to meet but exceed expectations by delivering high-quality data that can be relied upon.
In summary, flame spread testing of polyurethane foams plays a vital role in evaluating the fire safety properties of these materials.

Applied Standards
| Standard | Description |
|---|---|
| ASTM E84-21 | This standard specifies the methods for measuring the fire spread characteristics of materials using a narrow flame. It helps determine the relative flame spread and smoke development ratings. |
| ISO 6947-1:2013 | This international standard provides detailed procedures for conducting flame spread tests on flat surfaces. It includes specifications for specimen preparation, apparatus setup, test procedure, data analysis, and reporting. |
| ASTM E658/E658M-21 | This standard covers the use of the Universal Gravimetric Method for determining the loss on ignition (LOI) as a measure of total combustible matter in materials. LOI results are often used to assess flame retardancy. |
| EN 456-2:2018 | This European standard specifies requirements for fire safety testing equipment and methods, including those applicable to polyurethane foams. |
The application of these standards ensures that our flame spread tests are conducted consistently with industry best practices. This consistency translates into accurate and reliable results which are essential for meeting regulatory requirements and ensuring product safety.
Scope and Methodology
| Methodology | Description |
|---|---|
| Specimen Preparation | To begin the testing process, our team prepares the polyurethane foam specimens according to specified dimensions and weight limits. This ensures uniformity across all samples being tested. |
| Apparatus Setup | The apparatus used for flame spread testing includes a specially designed oven for heating the sample to predetermined temperatures, along with a controlled environment chamber where flames are applied under specific conditions. |
| Flame Application | A narrow flame is ignited and allowed to spread across the surface of the foam specimen. The rate at which this occurs determines the flame spread index (FSI). |
| Data Collection | During the test, key parameters such as the time taken for the fire to reach certain distances along the sample are recorded. Additionally, measurements related to smoke production and heat release rates may also be captured. |
| Analysis & Reporting | The collected data is then analyzed using statistical methods to calculate the flame spread index (FSI) and other relevant metrics. These findings form the basis of our final report which includes detailed descriptions, charts, graphs, and recommendations based on current best practices. |
Our methodology adheres strictly to established standards like ASTM E84-21 and ISO 6947-1:2013. By doing so, we ensure that all tests are conducted in a manner consistent with industry norms, thereby providing clients with confidence in the accuracy of our results.
