ASTM D1078 – Distillation Range of Volatile Organic Liquids
Volatile organic liquids may be found in petroleum distillates, spray lubricants, metal-working fluids, hydraulic oils and numerous other lubricating products. Release of the Volatile Organic Compounds (VOCs) during use may alter lubricant properties and emit potentially toxic vapors into the atmosphere. This method uses distillation to determine the boiling point profile of volatile organic liquids.
The sample is placed in a high temperature distillation apparatus and heated. The temperature of the vapor is recorded and graphed as a function of distillate volume produced. Reported is the temperature vs. distillate volume graph along with the temperature data corrected for atmospheric pressure.
