ASTM D8073-22

Overview

ASTM D8073-22 is the Standard Test Method for Determination of Water Separation Characteristics of Aviation Turbine Fuel by Small Scale Water Separation Instrument. Published by ASTM International, this standard defines a controlled method for evaluating how easily aviation turbine fuel can separate from water when passed through a water-coalescing filter. The procedure measures the influence of surfactants and other surface-active substances, which may impact the performance of fuel separation equipment and overall fuel cleanliness.

The test yields a Water Separation Index (WSI), indicating the capacity of aviation fuels to release entrained and emulsified water. Maintaining optimal water separability is critical in aviation fuels to ensure operational safety, fuel quality, and the reliable performance of aircraft engines.

Key Topics

• Purpose: Measures the impact of surfactants and additives on water separation efficiency in aviation turbine fuels.
• Test Range: WSI values range from 0.0 to 100.0, where higher values indicate better water separability.
• Detection Capabilities: Enables detection of refinery residues, processing carryover, or contaminants absorbed during handling and transportation.
• Test Method: Utilizes a specialized, small-scale water separation instrument, including a sonicator, dye detector, and coalescing filter, to simulate the water-removal process.
• Practicality: Designed for rapid, precise, and relatively simple operation, making it suitable for use at refineries, fuel terminals, pipelines, and in independent laboratories.
• Sample Handling: Emphasizes the importance of correct sample collection without pre-filtering, to avoid removing the very surfactants the test is designed to detect.

Applications

ASTM D8073-22 is essential for a range of stakeholders in the aviation fuel supply chain:

• Fuel Producers and Refiners: Assure the cleanliness and performance of aviation turbine fuel prior to distribution.
• Terminal Operators and Pipelines: Monitor fuel quality during storage and transfer to prevent water contamination, which could lead to engine problems or safety issues.
• Independent Testing Laboratories: Use the test to provide consistent, traceable quality assurance for aviation turbine fuels.
• Quality Assurance and Regulatory Compliance: Helps organizations meet industry and regulatory requirements for aviation fuel cleanliness by monitoring the presence of surfactants and potential contaminants.
• Operational Readiness: Rapid diagnosis of potential issues related to water separation in aviation fuels, supporting preventative maintenance and incident avoidance in aviation operations.
