ASTM D86 (Standard Test Method for Distillation of Petroleum Products)

ASTM D86 is a standardized procedure used to determine how a petroleum product (like gasoline or diesel) behaves when heated and boiled. It involves gradually heating a sample and recording the temperatures at which different amounts evaporate. This information helps identify the product’s composition, quality, and suitable applications. The method ensures consistency across laboratories and industries, providing essential data for refining, quality control, and regulatory purposes.
