Summary of Test Method
A weighed volume of sample is distilled at a low pressure between 50 and 0.1mmHg at at a specific distillation rate dependent of pressure. Fractions are taken at different temperatures as required by analysis. Mass of each fraction is obtained and yields by mass are calculated from the mass of each fraction. Density of each fraction is also obtained and yields by volume are calculated from volume of each fraction @ 15°C relative to total recovery.
