Abstract

This work presents the results of a survey carried out among Brazilian calibration laboratories accredited under ISO/IEC 17025:2005 with the objective to identify how these laboratories investigate the root causes of unsatisfactory results in proficiency testing. The survey was coordinated by the Brazilian accreditation body, the General Coordination for Accreditation (Cgcre), of the Institute of Metrology, Quality and Technology (Inmetro).
