– Accurate, Durable, and Easy to Operate for Distillation Analysis of Oils
In petroleum refining, fuel quality testing, and petroleum product research and development, distillation characteristics are fundamental indicators for evaluating the volatility, composition, and performance of oil products. The DFYF-101 Petroleum Products Distillation Tester is designed and manufactured in strict accordance with GB/T 6536 and ASTM D86 standards. It is suitable for atmospheric distillation determination of various petroleum products including gasoline, diesel, kerosene, jet fuel, naphtha, solvent oils, gas oils, and distillate fuels – making it essential equipment for refineries, quality inspection centers, fuel storage and transportation companies, and research institutions.
1. Standard Compliance and Applicable Samples
The DFYF-101 complies with the following international and national standards:
GB/T 6536 (Petroleum products – Determination of distillation at atmospheric pressure)
ASTM D86 (Standard Test Method for Distillation of Petroleum Products at Atmospheric Pressure)
Applicable sample types:
Natural gasoline (stabilized light hydrocarbons)
Automotive gasoline, aviation gasoline
Jet fuel
Special boiling point solvents, naphtha
Petroleum solvent oils, kerosene
Diesel, gas oils, distillate fuels
Other similar petroleum products
Distillation test results (initial boiling point, distillation temperatures at various recovery percentages, final boiling point, residue, etc.) are important bases for judging oil product quality and stability.
