The spread of flame is assessed by observing the distance and rate at which fire travels over the material’s surface, while heat evolved is measured as the amount of heat released during combustion. Smoke developed is quantified based on the visibility through the smoke produced during the test. Results from AS/NZS 1530.3 help in classifying materials based on their fire hazard properties, which is essential for ensuring that building materials meet safety requirements, contribute to the overall fire safety of structures, and align with fire safety engineering objectives.
