Vertical Flame Propagation Assessment Test
The Vertical Flame Propagation Assessment Test (VFPAT) is a critical component of fire resistance and flammability testing in building & infrastructure sectors. This test evaluates the flame propagation characteristics of materials used in construction, ensuring they meet safety standards and contribute to overall structural integrity during fires.
During this assessment, specimens are exposed to a controlled flame source for a specified duration under defined environmental conditions. The test measures the time it takes for flames to spread along the specimen's length, as well as the extent of burning and char formation. Specimens that exhibit rapid or uncontrolled flame propagation may fail to meet safety requirements, potentially leading to significant structural failures in buildings.
