Overview
The EMCEE Model 1140 Water Separation Index (WSI) Test Kit is a precision-engineered consumable system designed exclusively for use with the EMCEE Model 1140 Aviation Fuel Water Separation Index Analyzer. It implements the standardized coalescence–filtration–turbidimetric methodology defined in ASTM D7224, “Standard Test Method for Determining the Water Separation Characteristics of Aviation Turbine Fuels by Portable Separometer.” The test kit enables quantitative assessment of fuel’s ability to release entrained water under controlled vacuum-driven flow conditions—critical for evaluating the performance of fuel system coalescer filters and detecting surfactant contamination or fuel degradation that impairs water shedding capability. Each sealed, individually vacuum-packed unit delivers full assay reproducibility, traceability, and compliance integrity across laboratory, refinery, and field maintenance environments.
Key Features
- ASTM D7224-compliant consumables set, certified for use with EMCEE Model 1140 instrument platform
- Pre-assembled, single-use vacuum-sealed test pack—eliminates manual assembly errors and cross-contamination risk
- Included components: six calibrated 10 mL syringes, disposable pipette tips, coalescer filter cartridges pre-labeled with fuel type (e.g., Jet A, JP-5, JP-8) and corresponding ASTM method designation
- Integrated turbidity measurement glass tube (standard 16 mm OD × 100 mm length), optimized for consistent light transmission and particulate dispersion evaluation
- Dedicated distilled water vial (≥5 mL, USP-grade, certified low-turbidity) supplied per test pack to ensure reagent consistency and eliminate variability from external water sources
- Batch-numbered packaging with expiration date and QC certificate traceable to EMCEE manufacturing lot records
Sample Compatibility & Compliance
The Model 1140 WSI Test Kit is validated for aviation turbine fuels including Jet A, Jet A-1, JP-5, JP-8, and TS-1, as specified in ASTM D7224 Annex A1. Coalescer filters are pre-selected per fuel class and meet OEM specifications for pore structure, surface energy, and hydrophobic/hydrophilic balance. All components comply with ISO 8573-1 Class 2 compressed air purity requirements (where applicable during instrument operation) and conform to U.S. Department of Defense MIL-STD-3004B sampling and testing protocols. The test procedure supports GLP-compliant data generation when used with instrument audit-trail enabled firmware (v3.2+), satisfying traceability requirements under FAA Advisory Circular 150/5370-10F and EASA AMC 20-22.
Software & Data Management
While the test kit itself is hardware-based, its integration with the EMCEE Model 1140 analyzer ensures full digital workflow support. Instrument firmware logs each test execution—including operator ID, date/time stamp, ambient temperature/humidity, filter lot number, and raw turbidity absorbance values—at 1-second intervals. Exported CSV files contain calibrated WSI index calculations (unitless, 0–100 scale), pass/fail flags against specification limits (e.g., ASTM D7224 Table 1 thresholds), and metadata required for 21 CFR Part 11–compliant electronic records when paired with validated LIMS or ELN systems. Raw data retention complies with API RP 1172 and IATA Guidance Material for Fuel Quality Assurance Programs.
Applications
- Routine quality control of aviation turbine fuels at refineries, blending facilities, and airport fuel farms
- Performance verification of coalescer filter elements prior to installation and after service intervals
- Root cause analysis of water-related engine start failures or filter plugging incidents
- Surfactant contamination screening following tank cleaning, pipeline transfer, or biocide treatment
- Contractual compliance testing per airline fuel procurement specifications (e.g., ATA Spec 103, Shell SAE J1900)
- Regulatory submission support for FAA Form 8010-4 and EASA Form 1 documentation
FAQ
How many tests does one box contain?
Each box contains six individually vacuum-sealed test packs—each pack performs exactly one ASTM D7224 test.
Are the coalescer filters interchangeable between fuel types?
No. Filters are pre-labeled and engineered for specific fuel chemistries; using an incorrect filter invalidates ASTM D7224 compliance.
Is distilled water included in every test pack?
Yes. Each vacuum pack contains a sealed vial of USP-grade distilled water, eliminating reliance on lab-sourced reagents.
What is the shelf life of an unopened test pack?
24 months from manufacture date when stored at 15–25°C and 30–60% RH; see batch label for exact expiry.
Can this kit be used with non-EMCEE instruments?
No. Physical dimensions, syringe calibration, and filter mounting geometry are proprietary to the Model 1140 platform and not compatible with generic separometers.
