EN ISO 9705:2018 is an international standard that addresses the fire behavior of building materials and products. It provides a test method for evaluating the performance of construction products in fire conditions. This article aims to explain the key aspects of this standard in an easy-to-understand manner.
Understanding Fire Behavior
Before delving into the details of EN ISO 9705:2018, it is important to understand the basic principles of fire behavior. Fire requires three main components to burn: fuel, oxygen, and heat. The way different materials react to fire can significantly affect the overall fire safety of structures.
During a fire, the characteristics of materials such as how quickly they ignite, how fast the flames spread, and the amount of heat released play a crucial role in determining the severity and speed of fire growth. Understanding and testing these material properties are vital for ensuring the safety of buildings and protecting lives.

EN ISO 9705:2018, also known as the Room Corner Test or the SBI (Single Burning Item) test, provides a standardized method for evaluating the fire behavior of construction products in a full-scale room. It simulates real-life scenarios where a fire starts in a corner of a room and measures various parameters such as heat release, flame spread, and smoke production.
The test involves constructing a mock room with specific dimensions and adding a single ignition source. The product being tested is then mounted in a corner of the room. A well-defined heat flux is applied to the sample, and its reaction to fire is closely observed and measured. The test results help in assessing the fire performance of the product and determining its classification according to predefined criteria.
Benefits and Importance
EN ISO 9705:2018 is an essential standard for testing the fire behavior of construction products. It provides a standardized, reproducible method to evaluate the performance of materials in realistic fire conditions, allowing for accurate comparisons between different products. This helps manufacturers identify potential fire hazards and make necessary improvements to enhance the overall fire safety of their products.
The data generated from the tests can also be used by engineers, architects, building code regulators, and fire protection professionals to make informed decisions regarding material selection and design in order to create safer buildings. Compliance with EN ISO 9705:2018 ensures that products meet specific fire safety requirements, leading to increased confidence in their performance and better protection against fire incidents.
