Abstract :
In this work, the law of propagation of uncertainty is studied for complex system with nonlinear properties. Sensitivity analysis is carried out using the Taylor´s series expansion of higher-order terms than the usual one presented in the ISO (GUM). An experimental problem is considered to verify the obtained theoretical results and to asses the validity of the implemented formulation.
