Overview
The HX-WR1847A Automatic Aviation Fuel Water Reaction Tester is an engineered laboratory instrument designed to evaluate the water reaction behavior of aviation fuels—specifically aviation gasoline (AVGAS) and aviation turbine fuel (Jet A, Jet A-1, JP-5, and JP-8)—in accordance with standardized test methodologies. It operates on the principle of controlled mechanical agitation between a defined volume of fuel sample and distilled or deionized water under ambient atmospheric conditions, simulating real-world storage and handling scenarios where trace water ingress may occur. The device quantifies the physical interaction between fuel and water through precise measurement of interfacial stability, emulsion formation, separation time, and volumetric changes in the aqueous phase following agitation. This test is critical for assessing fuel cleanliness, additive performance, and susceptibility to microbial growth or corrosion—key parameters influencing flight safety and engine reliability.
Key Features
- Pneumatically driven vertical reciprocating motion system ensures consistent, repeatable agitation velocity and stroke amplitude—eliminating motor-induced vibration drift and thermal loading effects common in electromechanical alternatives.
- Microprocessor-based control unit enables programmable test duration (0–30 min), stroke count (1–999 cycles), and stroke length (standardized at 30 mm per ASTM D1094), with automatic cycle termination and digital display of elapsed time and completed strokes.
- Integrated timing and counting logic complies with the repeatability requirements of both GB/T 1793 and ASTM D1094, supporting GLP-compliant data logging when paired with optional external USB or RS-232 interfaces.
- Corrosion-resistant stainless-steel test chamber housing and borosilicate glass reaction tubes ensure long-term dimensional stability and optical clarity for visual assessment of phase separation and interface morphology.
- Self-contained design requires only compressed air (4–6 bar) and standard AC power (100–240 VAC, 50/60 Hz), minimizing infrastructure dependencies in QC labs or field-deployable testing environments.
Sample Compatibility & Compliance
The HX-WR1847A is validated for use with all conventional hydrocarbon-based aviation fuels meeting ASTM D910 (AVGAS), ASTM D1655 (Jet A/A-1), and MIL-DTL-83133 (JP-8) specifications. It accommodates sample volumes of 50 mL fuel + 50 mL water per test, as mandated by GB/T 1793 and ASTM D1094. The instrument supports manual or semi-automated interpretation of results—including water reaction rating (WRR), interfacial turbidity classification, and phase separation time—enabling direct correlation with fuel specification pass/fail criteria. All operational protocols align with ISO/IEC 17025:2017 general requirements for competence of testing and calibration laboratories, and support audit-ready documentation for GMP and FAA Part 145 maintenance facility compliance programs.
Software & Data Management
While the base HX-WR1847A operates via embedded firmware without proprietary software, optional firmware upgrades enable timestamped CSV export of test parameters (start time, stroke count, duration, operator ID) via USB or serial connection. When integrated into LIMS environments, exported logs meet FDA 21 CFR Part 11 requirements for electronic records and signatures when paired with validated user authentication and audit trail modules. No cloud connectivity or remote monitoring is implemented—ensuring full data sovereignty and compatibility with air-gapped laboratory networks.
Applications
- Quality control release testing of newly manufactured or reprocessed aviation fuels prior to distribution.
- Evaluation of fuel stability during long-term storage under varying temperature and humidity conditions.
- Assessment of detergent and anti-icing additive efficacy in mitigating water-induced phase separation.
- Root cause analysis of field-reported fuel filter blocking or engine fuel system corrosion incidents.
- Supporting technical service bulletins (TSBs) issued by OEMs such as Rolls-Royce, Pratt & Whitney, and GE Aviation regarding fuel-water compatibility thresholds.
FAQ
What standards does the HX-WR1847A comply with?
It fully conforms to GB/T 1793–2013 “Petroleum Products — Aviation Fuels — Water Reaction Test Method” and ASTM D1094–2022 “Standard Test Method for Water Reaction of Aviation Fuels”.
Is calibration traceable to NIST or other national metrology institutes?
The instrument does not require periodic calibration of mechanical stroke or timing functions; however, its pneumatic actuation system and microcontroller clock are factory-verified against ISO 9001-certified reference equipment. Users may perform in-house verification using stopwatch and calibrated ruler per ASTM D1094 Annex A1.
Can the HX-WR1847A be used for non-aviation fuels such as diesel or biodiesel?
No—it is purpose-built for aviation-grade hydrocarbons with narrow volatility and additive packages. Diesel or biodiesel testing requires alternative methods (e.g., ASTM D2709, D4377) and dedicated instrumentation due to differing interfacial dynamics and emulsion stability profiles.
What maintenance is required?
Routine inspection of pneumatic tubing, O-rings, and glassware integrity every 100 tests; annual verification of air pressure regulator accuracy and microcontroller firmware version against Spectra Invent’s latest release notes.
