Room corner testing to ISO 9705 is a standardized method used internationally to evaluate the fire performance of products and materials in an interior setting. This test simulates a real-life scenario where a fire starts in the corner of a room, allowing technicians to assess how materials contribute to fire growth and room flashover. The setup involves constructing a room with specific dimensions, where the test material is applied to the walls and ceiling. A burner placed in the corner of the room emits a defined heat output to ignite the material. During the test, various parameters such as flame spread, heat release rate, smoke production, and gas emissions are monitored and recorded. ISO 9705 provides critical data on the behaviour of materials in early-stage fires and their potential to reach flashover, helping to determine their suitability for use in building interiors and their impact on overall fire safety. This testing is pivotal for ensuring that materials meet stringent safety standards and are appropriately certified for use in various construction contexts.
