ASTM D8545

ASTM D8545 is a technical standard for determining the metal deactivator additive (MDA), specifically N,N′-disalicylidene-1,2-propanediamine, in aviation turbine fuel by high performance liquid chromatography (HPLC). It provides a standardized way to measure additive content in a fuel sample, helping support consistent testing and quality control. For fuel producers, laboratories, and purchasers, this standard is useful because it helps verify formulation control and supports more reliable product evaluation.

What is ASTM D8545?

ASTM D8545 describes a test method used to determine the content of a metal deactivator additive in aviation turbine fuel using HPLC. The standard is focused on one specific additive, MDA, and gives a technical basis for measuring it in a controlled laboratory setting. As an ASTM standard, it supports repeatable testing practices and helps align results across different users, which is important when confirming additive presence or comparing fuel samples against internal requirements.

Where is ASTM D8545 used?

This standard is typically used in laboratories and quality assurance environments that test aviation turbine fuel. It is relevant where fuel additives must be checked during production, blending, receiving inspection, or product verification. ASTM D8545 may also be used by organizations managing fuel specifications, analytical testing programs, or contract compliance work. Because it is based on HPLC, it is most closely associated with laboratory instrumentation and routine chemical analysis workflows.

Why is ASTM D8545 important?

ASTM D8545 matters because consistent measurement of metal deactivator additive content helps reduce uncertainty in fuel testing and product control. When additive levels need to be confirmed, a recognized test method supports more dependable results, smoother procurement decisions, and better compliance documentation. It can also help limit variation between laboratories and provide a clearer basis for quality control decisions in aviation turbine fuel programs. ASTM D8545 supports confidence in the analytical data used to evaluate fuel performance.
