A layer with a mass/unit area < 1,0 kg/m2 and a thickness < 1,0 mm is considered to be a non-substantial component Note 1 to entry: Two or more non-substantial layers that are adjacent to each other (i.e. with no substantial component(s) in between the layers) are regarded as one non-substantial component when they collectively comply with the requirements for a layer being a non-substantial component. 3.1.7 internal non-substantial component non-substantial component that is covered on both sides by at least one substantial component 3.1.8 external non-substantial component non-substantial component that is not covered on one side by a substantial component SIST EN 13501-1:2019

processes, the fully developed fire stage, the fire decay stage, and the environment and systems that will impact on the course of the fire. Note 3 to entry: Unlike deterministic fire analysis, where fire scenarios are individually selected and used as design fire scenarios, in fire risk assessment,, fire scenarios are used as representative fire scenarios within fire scenario clusters.
