Diseño y construcción de una cámara de inflamabilidad horizontal con extractor de gases para el laboratorio de inflamabilidad de la Facultad de Ingeniería Civil y Mecánica, para ensayos de reacción al fuego y determinación de los comportamientos de combustión de los materiales interiores de vehículos de carretera, tractores y maquinaria para la agricultura y silvicultura de acuerdo con la norma ISO 3795-2

Abstract

Nowadays, companies that manufacture bodywork must comply with a series of requirements and regulations, including the use of materials that safeguard the passenger's life in the event of an automobile accident; for this reason, the combustion rate of the materials used in the internal part of the bodywork must tend to zero or must be self-extinguishing. This project meets the requirements of the ISO 3795-2 standard, it also has several systems that are removable, which allowed easy maintenance and exchange of parts, has a control panel that allowed setting the time the specimen will be exposed to fire at the same time the internal temperature of the flammability chamber is controlled, once the flame touches the first point of measurement the user is able to operate the timer, then when the flame reaches the last point of measurement the operator could stop the timer. The results obtained in 64 samples of navaleado fabric are shown, demonstrating the correct operation of the flammability chamber, since its recovery factor is less than 10 percent.
