Reaction to Fire Testing for Extruded Polystyrene (XPS)
In fire safety testing, the Reaction to Fire (RtF) testing of extruded polystyrene foam (commonly known as XPS or expanded polystyrene foam) is a critical process. This test evaluates how a material behaves when exposed to flames and determines its resistance to ignition, flame spread, smoke production, and structural integrity loss.
Extruded Polystyrene Foam has been widely used in various sectors including construction, insulation, packaging, and even as an industrial-grade material for high-performance applications. Its unique properties make it a preferred choice due to its excellent thermal insulating ability and durability. However, when integrated into buildings or other structures, XPS must meet stringent fire safety standards.
ISO 1716:2015 specifies the test method for determining the reaction of materials to non-flaming ignition sources using a Cone Calorimeter. This standard is particularly relevant in this context as it provides detailed instructions on how to conduct these tests accurately and reliably. The goal is not only to assess the flammability but also to understand the potential risks associated with using XPS in different environments.
Our testing facility uses state-of-the-art equipment such as Cone Calorimeters, which simulate real-world fire conditions more effectively than traditional test methods like the Vertical Flame Test (ASTM E647-18). By employing these advanced tools, we can provide precise and reliable data that helps our clients make informed decisions about their products' safety.
The testing process involves preparing a uniform specimen of XPS according to specified dimensions. This ensures consistency across all samples tested under identical conditions. The sample is then placed in the Cone Calorimeter where it is subjected to controlled heating until it ignites spontaneously or meets other predefined criteria. During this period, various parameters such as heat release rate (HRR), smoke production rate (SPR), and mass loss are continuously monitored.
After the test concludes, our team analyzes all collected data points meticulously. They compare these results against internationally recognized standards like ISO 1716:2015 to ensure compliance with local regulations or customer requirements. Additionally, we generate detailed reports summarizing key findings along with recommendations for improving product performance if necessary.
Understanding the reaction of XPS during fire events is essential not only from a safety perspective but also because it impacts broader aspects like energy efficiency and sustainability goals within buildings. For instance, incorporating materials that pass rigorous RtF tests can contribute significantly towards achieving higher ratings on green building certifications such as LEED or BREEAM.
By offering this service, we aim to support industries across Europe and beyond by providing robust evidence demonstrating the fire safety attributes of extruded polystyrene foams used in various applications. Our expertise ensures that manufacturers and developers can confidently introduce safer products into markets while adhering to regulatory frameworks.

Industry Applications
The importance of Reaction to Fire Testing cannot be overstated for industries reliant upon extruded polystyrene foam. Construction firms, especially those involved in building insulation projects, benefit greatly from knowing how their materials perform under extreme fire conditions before they are incorporated into structures.
In the context of the construction sector, XPS plays a crucial role in providing thermal insulation to buildings while simultaneously contributing positively towards energy efficiency objectives. However, its effectiveness as an insulator can be compromised if it fails to meet stringent fire safety requirements. Therefore, conducting proper Reaction to Fire tests early in the development process allows architects and builders to select safer alternatives where necessary.
The packaging industry also relies heavily on XPS due to its lightweight yet robust nature which makes it ideal for protecting products during transit. When selecting packaging materials, manufacturers consider not only weight savings but also fire resistance characteristics since accidental fires can occur anywhere along the supply chain. By ensuring that their chosen insulation solutions pass appropriate RtF tests, companies demonstrate commitment to worker safety and environmental responsibility.
For industrial applications such as electrical enclosures or protective covers, XPS serves multiple purposes simultaneously - it acts both as an effective insulator against heat and electricity but also protects sensitive components from physical damage. In these cases too, passing rigorous Reaction to Fire tests ensures that the product meets essential safety standards required by regulatory bodies.
Regardless of application area, one thing remains constant: the need for reliable data regarding XPS' performance in case of fire incidents. Our testing services help bridge this gap by providing accurate and actionable insights based on empirical evidence gathered through controlled experiments.
Use Cases and Application Examples
One notable example comes from a leading manufacturer who sought to improve the fire safety profile of its extruded polystyrene foam product for use in commercial building insulation. By engaging us, they were able to conduct detailed Reaction to Fire tests using our advanced facilities. The resulting data revealed areas where improvements could be made without sacrificing performance or cost-effectiveness.
In another case study involving a global electronics company, XPS was evaluated as part of an overall package design intended for use in industrial settings. After rigorous testing, modifications were suggested which enhanced the material's resistance to ignition and reduced smoke emissions during simulated fires.
A third instance involved a supplier specializing in sustainable building materials who wanted assurance that their newly developed XPS insulation would meet strict fire safety standards. Our tests confirmed compliance with relevant international norms, thereby validating the product’s suitability for use in green buildings.
These examples illustrate how our Reaction to Fire Testing service can add value across diverse sectors by helping manufacturers ensure that their products not only work well but also remain safe under worst-case scenarios.
