Self-assessment model for testing and calibration laboratories based on ISO/IEC 17025:2017 requirements

Abstract This paper aims to propose a self-assessment model for evaluating the competence, impartiality, and consistent operation of testing and calibration laboratories, based on ISO/IEC 17025:2017 requirements. During the research, an attempt was 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. The main outcome of this research is an innovative self-assessment model for testing and calibration laboratories, with a view to supporting decisions for achieving accreditation. Notably, the results of the empirical study demonstrate that it is feasible to determine the readiness level of the Navy’s 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.
