Automatización de banco de pruebas para ensayos de inflamabilidad de materiales usados en la construcción de interiores de carrocerías

Abstract

The present work was in charge of automating the horizontal flammability machine of the laboratories of the Faculty, for which components were selected that allowed to control the different variables such as dosing times, temperatures, air and gas flow (LPG), essential for the generation of a flame height of 38 mm and exposure time of 15 seconds, specified in ISO Standard 3795. A control system was implemented with Arduino, which controls components such as servomotors, electrovalves, thermosensors, ignition systems between others, keeping the variables established above. After carrying out the tests, the proper functioning of the different components of the re-powered machine was verified, achieving optimum tests and determining temperatures and flammability indexes in the materials for the elaboration of internal automotive elements, which cannot be used for non-compliance a specific combustion index, established in Standards ISO 3795, NTE INEN 1323 and 1668.
