ASTM D8194

ASTM D8194 is a technical standard practice that addresses how to evaluate the suitability of 37 mm filter monitors and 47 mm filters used to determine particulate contaminant in aviation turbine fuels. It matters because the choice of filter and monitor can affect how reliably particulate contamination is measured during fuel testing. By providing a common evaluation framework, this ASTM standard supports more consistent laboratory practice, better comparability of results, and more confident quality control for aviation fuel assessment.

What is ASTM D8194?

ASTM D8194 is a practice for evaluating whether 37 mm filter monitors and 47 mm filters are suitable for use in determining particulate contaminant in aviation turbine fuels. The standard is centered on filter performance in a testing context, rather than on fuel composition itself. As a result, it is useful for laboratories and organizations that need to assess filtration-related test components before relying on them for routine measurement. ASTM D8194 helps define a more uniform basis for suitability evaluation.

Where is ASTM D8194 used?

This practice is commonly used in laboratories and technical environments that test aviation turbine fuels for particulate contamination. It is relevant wherever 37 mm filter monitors or 47 mm filters are selected for fuel cleanliness or contaminant determination workflows. ASTM D8194 is particularly useful in test method implementation, laboratory qualification, and equipment evaluation activities where filter choice can influence the reliability of results. It supports practical decision-making for organizations handling fuel quality testing and related compliance work.

Why is ASTM D8194 important?

ASTM D8194 helps promote consistency when evaluating filters used in particulate contaminant determination for aviation turbine fuels. That matters because unsuitable filters can introduce variability, reduce confidence in test results, or complicate quality control decisions. A clear practice for suitability evaluation supports more dependable procurement, method setup, and laboratory oversight. In applied settings, ASTM D8194 can help reduce risk by improving confidence that the selected filter monitor or filter is fit for the intended test purpose.
