Abstract: Used oil from internal combustion engines is an important instrument to diagnose their wear since it is the internal generated impurities evacuation medium. To obtain this objective many engine used oil samples must be evaluated. In this work, a method to correct and evaluate the metallic concentrations detected by spectrometric analysis from used lubricant is presented and the reference concentrations are defined, obtained and re-established. Besides. the limit concentrations are defined together with the sample characterization scales.

Resumen: El aceite usado procedente de motores de combustión interna es una herramienta importante para diagnosticar su desgaste por ser el medio de evacuación de todas las impurezas que se producen en su interior. Para lograr esta finalidad es necesario evaluar un gran número de muestras de aceite usado. En el presente artículo se propone un método para corregir y evaluar las concentraciones metálicas obtenidas a partir del análisis espectrométrico del lubricante usado. Se definen, obtienen y actualizan las concentraciones de referencia. Finalmente se definen las concentraciones de referencia junto con las escalas de caracterización de las muestras de aceite usado.
