    This technical project highlights the importance of implementing the technical requirements established in the NTE INEN-ISO/IEC 17025 standard. It proposes conducting interlaboratory proficiency tests in accordance with the NTE INEN-ISO 11925-2 standard, ensuring the reliability of the tests as stipulated in the NTE INENISO/IEC 17043 standard. The interlaboratory proficiency test involved analyzing the performance of the Mechanical Research Laboratory (LIM-UTA) in conducting tests, in compliance with the technical requirements of the NTE INEN-ISO/IEC 17043 standard for interlaboratory testing. The main objective was to evaluate the competence and reliability of flammability tests for construction materials, following the guidelines of the NTE INEN-ISO 11925-2 standard. The performance evaluation of LIM-UTA was carried out in accordance with the normative specifications, and the expected results included the validation of the test methodologies. The laboratory selected polycarbonate as the reference material for conducting flammability tests. Upon completion of the study, the verification and validation of the method used were carried out. Specialized software was employed to analyze the total Gage R&R, as well as aspects of precision, uncertainty, p-value, and accuracy, meeting the established criteria and achieving satisfactory results. Finally, a report was prepared in accordance with the NTE INEN-ISO/IEC 17043 standard to compare the performance results of the flammability test for construction materials.

    Nowadays it is important to comply with the quality requirements of construction products since their application involves the safety and life of people, it is essential that these products are fire resistant and in case of an adverse event such as this, it can be guaranteed that the spread of flame in the basic building materials is avoided. For this reason, the possibility of implementing the flammability test of construction products in the Mechanical Research Laboratory of the Faculty of Civil and Mechanical Engineering of the Technical University of Ambato has been proposed. This technical project is based on the design and manufacture of a flammability cabinet under the requirements of the NTE INEN - ISO 11925-2: 2010 standard that focuses on the testing of construction products, for this the equipment was designed considering the regulatory provisions and the equipment was built in AISI 304 steel using cutting processes and TIG welding with filler material and shielding gas, finally, the equipment was validated by testing three different materials such as: vinyl flooring, MDF and ceiling, with the test results under the criteria of NTE INEN - ISO 11925-2: 2010 it was determined that the equipment meets all the requirements.

    Diseño y construcción de un sistema de ventilación y medición de gases producidos en la cámara de inflamabilidad del Laboratorio de Ingeniería Mecánica de la Universidad Técnica de Ambato

    Safety afety in the work environment as well as control of gaseous emissions towards the environment are trends in the modern industrial environment, since it seeks to implement processes that are friendly to the environment and minimize the impact on it, which is why This technical project constitutes the study of design and construction alternatives for a localized extraction system for the horizontal and vertical flammability chamber of the Faculty of Civil and Mechanical Engineering, as well as determining the degree of contamination in parts per million that is generated by test a material in said chamber. The necessary parameters were established for the design and construction of the localized ventilation system based on the ACGIH (AMERICAN CONFERENCE OF GOVERNMENTAL INDUSTRIAL HYGIENISTS) standard, such as height, density and temperature of gases, flow rates, etc. The necessary conditions were identified to carry out the combustion test and the emission of combustion products gases in stationary sources as established by NT 001 and EPA PART 60 appendix A. Then, materials in the flammability chamber were tested to verify the proper functioning of the extraction system and perform a combustion test based on EPA PART 60 APPENDIX A METHOD 3A, 6C, 7E, considering the characteristics of the Insigth Fyrite Plus Gas Analyzer. With the tests carried out it was found that the material composed of resin and natural fiber reinforcement has a concentration of 8 PPM of 𝐶𝑂2 (corresponding to 14.39 mg / m3) an average temperature of 23.22 grade C and 20.9 percent of 𝑂2,, with a gray-dark color, the material composed of polyester resin and fiberglass reinforcement has a concentration of 3 PPM of 𝐶𝑂2 (corresponding to 5.4mg / m3), an average temperature of 23.13 grade C and 20.9 percent of 𝑂2,, with a gray color, the microsuede material (corosil), has a concentration of 11 PPM of 𝐶𝑂2 (corresponding to 19.79 mg / m3), an average temperature of 18.03 grade C and 20.9 percent of 𝑂2,, With a gray-dark coloration, the alcantara material has a concentration of 3 PPM of 𝐶𝑂2, (corresponding to 5.4 mg / m3) an average temperature of 20.91 grade C and 20.9 percent of 𝑂2,, with a gray coloration.
