Full title and description
Standard Test Method for Trace Metals in Gas Turbine Fuels by Atomic Absorption and Flame Emission Spectroscopy — test procedure for measuring selected trace metals in specification gas-turbine fuels using atomic absorption and flame emission techniques.
Abstract
This standard (D3605-22) specifies procedures to determine sodium, lead, calcium, and vanadium in gas turbine fuels (Specification D2880 Grade Nos. 0‑GT through 4‑GT) at the 0.5 mg/kg reporting level. Samples are prepared using the method of standard additions and analyzed by atomic absorption or flame emission spectroscopy with instrument and flame selections specified for each element.
General information
- Status: Published / Active.
- Publication date: Current edition approved October 1, 2022 (published 2022).
- Publisher: ASTM International.
- ICS / categories: 75.160.20 (Liquid fuels).
- Edition / version: D3605-22 (2022 revision).
- Number of pages: 4 pages.
Scope
The test method covers determination of sodium, lead, calcium, and vanadium in Specification D2880 Grade Nos. 0‑GT through 4‑GT fuels at nominal 0.5 mg/kg levels for each element. It is intended for oil‑soluble metals (not waterborne contaminants in oil–water mixtures). Test Method D6728 is listed as an alternative for these determinations.
Key topics and requirements
- Analytes: sodium (Na), lead (Pb), calcium (Ca), vanadium (V).
- Reporting/target level: approximately 0.5 mg/kg for each listed element.
- Analytical modes: atomic absorption spectroscopy (primary) and flame emission spectroscopy (alternative where indicated).
- Flame/optical details: lead by atomic absorption in air–acetylene; sodium by atomic absorption or atomic emission in air–acetylene; calcium and vanadium by atomic absorption or emission using a nitrous‑oxide/acetylene flame (details in method text).
- Sample preparation: method of standard additions to address matrix effects and enable direct analysis in the flame/AA mode.
- Applicability: oil‑soluble metal determination in D2880 gas turbine fuel grades; not intended for waterborne contaminants in emulsions.
- Precision and scope notes: precision statement applies to Subcommittee D02.03 (Elemental Analysis); users may add potassium determination by analogous technique if required.
Typical use and users
Used by petroleum and fuel testing laboratories, refineries, aviation fuel quality control, turbine operators, lubricant/fuel research labs, and regulatory/inspection bodies concerned with metal contamination that can affect corrosion, deposits, or turbine component life.
