    This project presents the collection of information to meet one of the requirements requested by ISO/IEC 17025:2017 with the performance of interlaboratory proficiency testing based on the standard NTE INEN/IEC 17043:2010 establishing the parameters of the standard NTE INEN-ISO 3795. In the present project, comparisons were made of the performance of the Mechanical Research Laboratory of the Technical University of Ambato (LIM-UTA) in the performance of flammability proficiency tests, following the technical requirements established by the interlaboratory standard NTE INEN-ISO/IEC 17043:2010. The main objective is the accreditation and evaluation of the competence and reliability of the laboratory in the execution of the tests according to the parameters established by NTE INEN-ISO 3795. The comparison of LIM-UTA's performance was carried out following the guidelines established in the standards used. Representative samples of flammable textile materials were selected according to NTE INEN-ISO 3795 for evaluation. These samples were distributed to different participating laboratories, including LIM-UTA, in order to carry out the flammability suitability tests. At the end of the study, a report will be submitted analyzing the deviations, discrepancies and various parameters such as accuracy and the laboratory's ability to meet the limits of the acceptability criteria required by the NTE INEN-ISO/IEC 17043:2010 standard for the proficiency testing program.

    The present technical project was developed as a need to offer more services to the community, led by the LIM-UTA research laboratory. For the redesign, a recognition of the needs and parameters such as functionality, resistance and usefulness that make the flammability chamber an appropriate test bench for flame resistance tests in textile materials, was carried out, adhering to the ASTM D6413 standard. A methane combustion study is developed, later an analysis of the mass flow was carried out that allowed to know the losses by pipe and accessories in the installed pressure regulating train. Alternatives for the self-ignition control system and pressure regulating train parts were selected. The flame resistance tests were carried out using a textile material characteristic in the body industry, consequently a statistical analysis was made validating the test method (vertical test), finally the technical documentation of the vertical flammability test chamber was implemented in accordance with the Ecuadorian technical standard "NTE 17025".
