Modelo de autoavaliação para laboratórios de ensaio e calibração baseado na norma ABNT NBR ISO/IEC 17025:2017

Abstract

This dissertation aims to propose a self-assessment model for evaluating the competence, impartiality and consistent operation of testing and calibration laboratories, based on ABNT NBR ISO/IEC 17025:2017 standard. An attempt is made to demonstrate the applicability of the proposed model through the development of a case study in one of the Brazilian Navy's Testing and Calibration Laboratories. This research can be considered applied, descriptive and methodological. The methodology encompasses literature review and documentary research; development of a self assessment model for evaluating the competence, impartiality and operational consistency of testing and calibration laboratories; construction of the analytical hierarchical structure with the key and detailed elements that integrate the model; application of the analytical hierarchy process (AHP) method to define the weights of the evaluation criteria, with the participation of invited experts; development of a case study within one of theBrazilian Navy's Test and Calibration Laboratories; discussion of results and formulation of conclusions and recommendations. The main outcome of this research is an innovative self-assessment model for testing and calibration laboratories, with a view to supporting decisions concerning the accreditation process of these laboratories according to the mentioned Standard. Not ably, the results of the case study demonstrate that it is feasible to determine the maturity level of the Laboratory in compliance with the requirements of the mentioned standard. Also, they allowed identifying opportunities for improvement of the current management system of the Laboratory.
