Estimativa da incerteza de medição nos ensaios de resistência elétrica de fios e cabos elétricos para tensões nominais de até 450/750V . Revista de Gestão e Secretariado, [S. l.], v. 15, n. 10, p. e4372, 2024. DOI: 10.7769/gesec.v15i10.4372. Disponível em: https://ojs.revistagesec.org.br/secretariado/article/view/4372.https://rigalileo.itegam.org.br/handle/123456789/182The electrical wire and cable market faces challenges with low-quality products, including electrical resistances above normative limits, which can lead to risks such as fires. This study addresses the estimation of measurement uncertainty in electrical resistance tests for wires and cables with nominal voltages up to 450/750V, applying the "top-down" methodology and using the Ishikawa Diagram to identify uncertainty sources. Measurements were conducted on collected samples using calibrated equipment. The developed mathematical model proved effective in ensuring compliance and enhancing safety.pdf.Incerteza de MediçãoResistência ElétricaConformidade de ProdutosFios e Cabos ElétricosSegurança ElétricaArtigo3.04.00.00-7 Engenharia Elétrica
