ASTM D8049

ASTM D8049 is a technical standard for measuring the concentration, count, and size distribution of solid particles and water in light and middle distillate fuels using a direct imaging analyzer. It helps define a consistent approach for evaluating fuel cleanliness and contamination levels, which can be important for quality control, handling, and product assessment. By focusing on particle and water characterization, the standard supports more reliable testing results and clearer comparison across samples.

What is ASTM D8049?

This standard describes a test method for determining how many solid particles and water droplets are present in light and middle distillate fuels, along with their concentration and size distribution. ASTM D8049 is centered on direct imaging analyzer technology, which is used to capture and assess particulate and water-related features in a fuel sample. In practical terms, it provides a structured way to examine fuel contamination and compare results in a repeatable, standardized format.

Where is ASTM D8049 used?

ASTM D8049 is commonly used in fuel testing and quality assurance settings where light and middle distillate fuels are evaluated before or during use. It is relevant in laboratories, inspection workflows, and other technical environments that need to measure particulate and water content in fuel samples. The method may be applied to support incoming material checks, storage monitoring, and general cleanliness assessments for distillate fuel handling and distribution.

Why is ASTM D8049 important?

This standard matters because solid particles and water can affect fuel quality, consistency, and downstream performance. ASTM D8049 gives users a common test method that supports more dependable comparisons between samples, suppliers, and test results. It is useful for compliance-related evaluation, quality control, and risk reduction when fuel cleanliness is a concern. For organizations that rely on distillate fuel testing, the standard can improve confidence in technical decisions.
