This document provides analytical test results for base oil type SN-150, including measurements for appearance, relative density, color, kinematic viscosity at 40C and 100C, viscosity index, flash point, neutralization number, ash content, PCBs, and lead content. The results show the oil has a clear and bright appearance, relative density of 0.871, color L3, viscosity of 25.10 cst at 40C and 4.54 cst at 100C, viscosity index of 100, flash point of 190C, neutralization number and ash content both less than 0.03, and no detectable PCBs or lead.
