Abstract: This study analyses the possibility of using beef tallow biodiesel transesterified with ethanol, provided by Universidade Federal Fluminense, as a viscosity reference material for biodiesels. The quantity viscosity was measured with capillary viscometers, according to Brazilian standards, in a temperature range between 20 ºC and 40 ºC for characterisation, and at 40 ºC for homogeneity, in short-term stability (90 days) and long-term stability (450 days). Thirty-nine samples were stored, 9 at 45 ºC, 6 at 4 ºC and 24 at 20 ºC. The behaviour of viscosity is analysed considering the estimated uncertainty of measurements for characterisation, homogeneity and stability. The reason to study a transesterified biofuel with ethanol lies in the fact that it is easy to produce this fluid from sugarcane in Brazil.
