The ISO 3405 standard, developed by the International Organization for Standardization (ISO), describes a test method for determining the distillation properties of light and medium distillates obtained from petroleum and related products of synthetic or biological origin, with initial boiling points above 0 degrees and final boiling points below approximately 40 degrees, using manual or automated equipment. Light distillates generally include automotive engine gasoline, automotive engine ethanol fuel blends containing up to 85% ethanol, and aviation gasoline. Medium distillates generally include aviation turbine fuel, kerosene, diesel, diesel containing up to 30% fatty acid methyl ester, burner fuel, and marine fuels that do not contain significant residues. For the purposes of this standard, the percentage expression is used to represent the volumetric ratio of a material.
The distillation (volatility) properties of hydrocarbons and related products of synthetic or biological origin have a significant impact on their safety and performance, especially when it comes to fuels and solvents. The boiling range provides important information about composition and behavior during storage and use, and evaporation rate is an important factor in the application of many solvents.
To control end-use performance and to regulate the formation of vapors (volatile organic compounds, VOC) that form explosive mixtures with air or escape to the atmosphere as emissions, limit values are applied to the distillation properties specified in most distilled petroleum product and liquid fuel specifications.
For the purposes of this standard, the term "starting boiling point" refers to the thermometer reading observed when the first drop of condensate falls from the bottom end of the condenser tube. The term "final boiling point" refers to the final maximum thermometer reading obtained during the test. The term "percentage of evaporation" is the sum of the percentage of recovered and the percentage of lost.
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, test for the determination of the distillation properties of petroleum and related products obtained from natural or synthetic sources at atmospheric pressure within the scope of ISO 3405 standard. also provides services.
