    Fire safety is crucial in construction materials, making the implementation of safety standards with certifications essential to ensure their reliability. This research analyzes the flammability of polyvinyl chloride (PVC) plates used in electrical outlets, evaluated under the NTE INEN – ISO 11925 – 2 standard. The objective of this test is to determine the flammability index of PVC. The material was conditioned to meet the parameters imposed by the standard and exposed to a flame source for 30 and 60 seconds in two configurations: edge and surface, as well as longitudinal and transverse orientations. The parameters evaluated according to the standard included ignition, flame propagation up to 150 mm, material dripping, and filter paper ignition. The gases generated were captured using a gas meter, while thermal characterization and the use of a thermographic camera were valuable in developing a flammability test simulation. The test results were recorded and analyzed according to the standard, helping to determine the flammability index. Due to its characteristics, polyvinyl chloride (PVC) has a low flammability index and was classified based on its fire reaction behavior as: A1 – s2, d0. Finally, the toxicity levels of the emitted gases were analyzed, and the simulation results revealed the percentage variation in temperatures between the actual and simulated scenarios, providing a complementary contribution to this research.
