ASTM D8166

ASTM D8166 is the ASTM standard for sizing and counting particulates in middle distillate fuels and biodiesel blend fuels from B6 to B20 using continuous flow and bottle sampler particle contamination monitors. It helps define a consistent approach for evaluating particulate contamination in these fuels, supporting quality control, product handling, and comparative testing. For buyers and laboratories, this standard is useful when particulate cleanliness matters for fuel performance, storage, and compliance-related verification.

Overview of ASTM D8166

ASTM D8166 focuses on a test method for particulate sizing and counting in middle distillate fuels and biodiesel blends, specifically within the B6 to B20 range. The method uses continuous flow and bottle sampler particle contamination monitors, which points to a practical, instrument-based approach for assessing contamination levels. As an ASTM standard, it provides a shared technical basis for generating more consistent results across testing programs, helping users compare fuel cleanliness in a repeatable way.

Common use cases of ASTM D8166

This standard is commonly used in fuel testing workflows where middle distillate fuels and biodiesel blend samples must be checked for particle contamination. It may support laboratory quality control, incoming fuel inspection, storage and distribution checks, and product evaluation before use or transfer. ASTM D8166 is also relevant when monitoring systems rely on continuous flow or bottle sampler contamination monitors, since it helps align testing practice with a defined ASTM method.

Benefits of using ASTM D8166

Using ASTM D8166 can improve consistency in how particulate contamination is measured and reported for applicable fuels. That is valuable for compliance efforts, procurement decisions, and routine quality control because it gives stakeholders a common test method to follow. It may also help reduce uncertainty when comparing results from different samples, instruments, or testing locations. For organizations handling middle distillate fuels and biodiesel blends, the standard supports more reliable technical evaluation and risk awareness.
