    Automatización de un banco de pruebas para ensayos de inflamabilidad vertical de materiales textiles utilizados en el interior de las carrocerías

    The present technical titration project was based on the need to perform vertical flammability tests, to which it is necessary to implement an automated system that allows to adequately controlling the parameters specified in the corresponding standard. This will provide facilities to body manufacturers in the country, as the Ecuadorian technical regulation establishes a requirement for body manufacturers to standardize their units, also considering that the largest percentage of body manufacturers are located in zone three, to which we belong. For the execution of the project began with the revision of ASTM D 6413, which establishes the parameters of construction and operation of the vertical flammability test chamber, which establishes the parameters to control to select the necessary components for the automation of the vertical flammability testing machine. Selected components are proceeded with the assembly of the same and the design of the software that will allow the control of the machine from a computer, in addition to allowing the recording of data of the test performed. To perform the functional tests, five materials used inside the bodies were selected, with which they are sized according to the specifications of the standard used to proceed with the execution of the vertical flammability tests. In this test, the sample is subjected to a flame source of 38 mm in height for a period of 12 seconds, after which the performance data of each of the tested samples is observed and recorded to determine the required flammability index by the Ecuadorian technical regulation, in addition to calculating the carbonization index and post-glare time of each material tested.
