Reaction to fire class is the main fire characteristic (mandatory) for part of construction products and electrical cables. However determination of the reaction to fire class of electrical cables is very expensive.
Created method by research team of technical university in Bratislava with the background in material technology allows reaction to fire class of electrical cables determine from photographs of their flames (during fire test). This method consists of two steps. The sample with the known reaction to fire class is tested and photographs of its flame are taken during this test. Taken photos are used for (convolutional) neural network training in the first step. After training the (convolutional) neural network is used for checking declared reaction to fire test of tested cable sample (from photos of its flame taken during second step) in the second step.
The institution is seeking an industrial partner for licensing for the further development and commercionalization of mentioned technology.
