Heat of combustion testing according to ISO 1716 is a standardised method used to determine the potential energy content of building materials in the form of heat release during combustion. This test is crucial for assessing how much heat a material can potentially contribute to a fire once ignited. ISO 1716 involves measuring the gross calorific value, which is the total heat released when a material is completely burned in a controlled environment, typically using a bomb calorimeter. This parameter is essential for calculating the fire load of a building and understanding the fire behaviour of materials under actual fire conditions. The results from this test help in classifying materials based on their combustibility and energy contribution to fires, aiding in fire safety engineering and compliance with building fire safety standards. Such testing is pivotal for materials used in construction, furnishing, and other applications where fire safety is a critical concern.
