Full title and description

Standard Test Method for Determination of Phenolic Antioxidants and Fuel System Icing Inhibitors in Aviation Turbine Fuels — a laboratory test method that uses solid phase extraction (SPE) followed by gas chromatography–mass spectrometry (GC/MS) to selectively identify and quantify hindered phenolic antioxidants and common fuel system icing inhibitors in aviation turbine fuels.

Abstract

This standard (D8564-24) specifies an SPE–GC/MS procedure to determine concentrations of hindered phenolic antioxidants (approx. 1–50 mg/L) and fuel system icing inhibitors (approx. 450–4500 mg/L) in aviation turbine fuels, including petroleum-derived jet fuels and approved synthetic aviation turbine fuels (SAF). The method provides selective identification and quantification for a defined set of antioxidant and icing-inhibitor compounds and includes interim precision data and application guidance.

Scope

This test method covers determination, in the interim precision ranges, of selected hindered phenolic antioxidants (approximately 1 mg/L to 50 mg/L) and fuel system icing inhibitors (approximately 450 mg/L to 4500 mg/L) in aviation turbine fuels using solid phase extraction with GC/MS detection (SPE‑GC/MS). It applies to petroleum jet fuels and synthetic aviation turbine fuels and their blends, and notes that higher concentrations can be measured though full precision beyond the interim range has not been established. Appendix material provides recovery and accuracy information; interim precision was determined following Practice D6300.

Key topics and requirements

• Analyte classes: hindered phenolic antioxidants (selected tertiary‑butyl phenols and analogs) and fuel system icing inhibitors (including DiGME and EGM).
• Method principle: solid phase extraction (SPE) sample preparation followed by GC/MS for selective identification and quantification.
• Validated (interim) concentration ranges: antioxidants ~1–50 mg/L; icing inhibitors ~450–4500 mg/L.
• Precision and reproducibility: interim precision established via a limited multi‑laboratory/repeatability study (see ASTM Research Report RR:D02‑2074).
• Applicability: suitable for petroleum jet fuels and approved synthetic blending components (SAF) meeting relevant fuel specifications.
• Notes and limitations: does not claim to identify every possible antioxidant or icing inhibitor; users should consult product specifications and safety/regulatory requirements.

Typical use and users

Routine and investigative laboratory analysis in fuel quality control and quality assurance programs: petroleum refiners, fuel additive suppliers, aviation fuel testing laboratories, airline technical departments, OEM/engine manufacturers, regulatory agencies, and standards committees. The method is used where selective quantification of antioxidants and icing inhibitors is required for storage stability, specification compliance, fuel handling, and forensic investigations.

Related standards

References and related documents commonly associated with this test method include: ASTM D5006 (field method for certain icing inhibitors — less selective), aviation fuel specification ASTM D1655, synthetic aviation fuel specification ASTM D7566, Practice D6300 (precision), and various national/defence specifications (for example DEF‑STAN 91‑091 and GB 6537) that list additives. Users should consult these standards for specification limits and complementary test methods.
