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.
