Full title and description

St ASTM RR‑D02‑2071 2024 — Research Report (RR:D02‑2071) documenting an equivalence evaluation of the TO10 apparatus (AD Systems) against the existing apparatus listed in Table 1 of ASTM D3241, Test Method for Thermal Oxidation Stability of Aviation Turbine Fuels. The report is published by ASTM International as a Research Report supporting the D02 committee work on fuel thermal/combustion properties.

Abstract

This research report (RR:D02‑2071) summarizes an interlaboratory/equipment‑equivalence study that compares test results obtained using the new TO10 apparatus (AD Systems) with results from the apparatus types referenced in ASTM D3241 Table 1. The objective is to demonstrate equivalence of the TO10 model for measuring thermal oxidation stability and deposit tendency of aviation turbine fuels under the D3241 procedure. Findings inform the D02 subcommittee and users about the acceptability of the TO10 configuration for D3241 testing.

Scope

The report documents the equivalence evaluation of a specific commercially available apparatus model (TO10 by AD Systems) against the apparatus types enumerated in ASTM D3241 Table 1. It covers test execution, comparison of key measurement outputs (deposit formation metrics, differential pressure, tube appearance/ratings and other D3241 endpoints), statistical comparison/acceptability criteria used by the D02 subcommittee, and conclusions about whether the TO10 produces results sufficiently equivalent to the reference apparatus under the D3241 procedure. The underlying D3241 method rates fuel tendency to form deposits when in contact with heated surfaces in gas turbine fuel systems.

Key topics and requirements

• Equipment equivalence: protocol and acceptance criteria for evaluating a new apparatus model (TO10) against reference apparatus in D3241 Table 1.
• Test method context: thermal oxidation stability testing of aviation turbine fuels per ASTM D3241 (heater tube test, deposit measurement, differential pressure/deposition metrics).
• Interlaboratory / comparative data: summary of comparative measurements, variability, and statistical assessment used to judge equivalence.
• Practical implications: guidance for test laboratories and instrument vendors on using TO10 for routine D3241 testing if equivalence criteria are met.
• Traceability to D02 subcommittee requirements and test method references.

Typical use and users

Primary users are fuel testing laboratories, instrument vendors (AD Systems and competitors), fuel producers and formulators, aircraft/engine maintenance organizations, regulatory and standards bodies, and R&D groups concerned with fuel thermal stability and deposit formation. The report is used to decide whether the TO10 apparatus is acceptable for D3241 testing and to inform procurement, method implementation and interlaboratory comparisons.

FAQ

Q: What is this standard?

A: This item is an ASTM Research Report (RR:D02‑2071, titled St ASTM RR‑D02‑2071 2024) that documents an equivalence evaluation of the TO10 apparatus (AD Systems) for use with ASTM D3241, the Test Method for Thermal Oxidation Stability of Aviation Turbine Fuels. It is a supporting research report rather than a standalone test standard.

Q: What does it cover?

A: It covers the comparative testing and analysis performed to determine whether the TO10 apparatus yields results equivalent to the apparatus types listed in D3241 Table 1 for measuring deposit formation and related endpoints under the D3241 heater‑tube procedure. The underlying D3241 method defines how thermal oxidation stability and deposit tendency are assessed.

Q: Who typically uses it?

A: Fuel testing laboratories, instrument manufacturers, fuel producers, engine/aircraft maintenance and qualification teams, and standards committees use the report to guide equipment acceptance, method implementation, and to support test method precision and reproducibility assessments.

Q: Is it current or superseded?

A: The research report listing (RR:D02‑2071) is presented as approved in 2024 and is active as an ASTM Research Report supporting the current D3241 method; the D3241 standard itself is maintained as an active document (most recent D3241 editions listed by ASTM include updates through 2024). Users should confirm the latest D3241 edition and any adjuncts before test implementation.

Q: Is it part of a series?

A: Yes — it is an ASTM Research Report produced under Committee D02 (Subcommittee D02.J0) and is one of a series of RR:D02 research reports that provide interlaboratory/precision or equipment‑equivalence data to support D02 standards and test methods.

Q: What are the key keywords?

A: Thermal oxidation stability; fuel deposits; heater tube; D3241; apparatus equivalence; TO10; AD Systems; aviation turbine fuel testing; RR:D02‑2071.
