Apparatus The following items will be required for this procedure. Ensure each item is available before proceeding to the next step of this procedure: 1 Micro-Separometer – the unit is completely portable and self-contained, capable of operating on an internal rechargeable battery pack or being connected to an A-C power resource. Connection to an A-C power source will provide power to the unit and effect battery recharge. See Figure 1. 2Syringe Plug – a plastic plug used to stopper the syringe during the CLEAN and EMULSION cycles. See Figure 2. 3Syringe with Plunger – a disposable plastic syringe. 4Vials – 25 mm outside diameter, Premark for proper alignment in the turbidimeter well. 5Alumicel Coalescer – an expendable, precalibrated cell with a tapered end to fit the syringe. 6 Pipette with Plastic Tip – an automatic hand held pipette with a disposable plastic tip. A Pipet is supplied with each Micro- Separometer. 7 Wire Aid – a piece of wire with a loop on one end, used during the test to release the air trapped in the barrel of the syringe when the plunger is being inserted. A wire aid is supplied with each Micro-Separometer. 8Water Container – a clean container for distilled water. 9 Beaker, Catch Pan, or Plastic Container – used to receive the waste fuel during the coalescence period of the test. One is supplied with the Micro-Separometer. 10 Micro-Separometer Six Pack – designed to fit inside the top lid of the Micro-Separometer. It contains 6 each of a new syringe, Pipet tip, test vials, syringe plug and Alumicel coalescer cell. See Figure 3.

AreaUnitOperating Procedure #Certified byRevision #DatePage 3LabOPS-LB-NM-011B. Gereighty29/10/072 of 5 Reagents The following reagents will be required for this procedure. Ensure all reagents are available in the proper quantities before proceeding to the next step. 1Aerosol OT, solid (100% dry) bis-2-ethylhexyl sodium sulfosuccinate. 2Toluene, ASS reagent grade. 3Dispersing Agent-Toluene Solution containing 1 mg of Aerosol OT per ml of toluene. 4Reference Fluid Base - a surfactant-free, clean hydrocarbon material which is used to verify proper operation. 5 Reference Fluids – for checking the operational performance of the Micro-Separomater instrument. It consists of increasing concentrations (0 to 1.2 ml/L) of dispersing agent added to the reference fluid. The MSEP-A rating for this range of concentrations appears in Table 4. If the results do not fall within the range of limits in Table 4, the reference fluid shall be discarded and a fresh quantity of reference fluid prepared and the check repeated. Repeated out of tolerance test results are cause for returning the instrument to the factory for adjustment and calibration. 6Water-clean, distilled, and surfactant free. Standard Test Method for Determining Water Characteristic of Aviation Turbine Fuels by Portable Separometer (continued) Preparation of Appartus The following steps must be completed prior to performing the actual procedure: 1 Place the Micro-Separometer on a clean workbench in an area where the temperature is between 65 F and 85 F, and does not vary more than +/- 3 F. 2Open the case and remove the six pack from the lid. 3Raise the right panel until it is completely vertical and locked in place. 4If A-C power is available, connect the power cord to the instrument. 5If the internal battery power is used, assure that the batteries are charged sufficiently to perform the desired number of tests. 6 Turn the instrument on by depressing the ON switch. The ON power indicator light will alternately pulse on and off when the instrument is connected to an A-C power source and will stay on continuously when operated by the battery pack. 7Let the instrument warm up for 15 minutes. 8Have your test supplies ready: syringe, syringe plug, cell, pipette, pipette tip, wire aid, water and waste container.  Procedure Completed Date: Prepared By: Approved By:

Gereighty29/10/073 of 5 Sample Preparation The test sample must be prepared as described below before performing the test: 1Extreme care and cleanliness are required in taking samples. The test fuel should be caught in a clean container. 2 Do not filter the sample. If the test fuel is contaminated with particulate matter, allow such material to settle out of the fuel before starting the test. 3The sample should be within the test temperature limits, 65 F to 85 F, +/- 3 F. Standard Test Method for Determining Water Characteristic of Aviation Turbine Fuels by Portable Separometer (continued) Test Procedure 1Depress OPERATING MODE A switch. 2Remove the plunger from the syringe barrel. 3Insert a plug into the bottom of the syringe. 4Add 50 ml of the test fuel to the syringe. 5Place the syringe on the emulsifier. 6Twist the syringe to lock in place. 7Add 15 – 20 ml of the test fuel to a clean vial (1/2 full). 8Insert the vial in the turbidimeter well. 9Align the black mark on the vial with the white mark on the front panel. 10Depress the START switch to initiate the CLEANING cycle. This will also initiate the Automatic Program. See Table 3. 11When the mixer stops, remove the syringe from the emulsifier. 12Discard the fuel and drain the syringe thoroughly. 13Add 50 ml of fresh test fuel to the syringe. 14Attach a fresh plastic tip to the pipette. 15Push in the plunger on the pipette. 16Immerse the tip of the pipette just below the water surface and withdraw 50 microliters of water. 17Withdraw the pipette from the water slowly in order to avoid water drips adhering to the outside of the tip.  Procedure Completed Date: Prepared By: Approved By:

Gereighty29/10/074 of 5 Test Procedure (continued) 18Immerse the tip of the pipette just below the test fuel surface in the center of the syringe. 19Inject the water into the test fuel. 20Slowly withdraw the pipette out of the syringe. 21Place the syringe barrel on the emulsifier. 22Twist the syringe to lock in place. 23Depress the START switch to initiate emulsification. 24 Adjust the meter to read 100 by using the UP (↑) or DOWN (↓) Arrow switch. The meter adjustment period lasts 10 seconds. If the adjustment cannot be completed at this time, a final adjustment can be made during the second meter adjustment period. When the mixer stops, you have 30 seconds to prepare for coalescence. 25When the mixer stops, remove the syringe from the emulsifier. 26Partially insert the plunger in the syringe. With or without the help of the wire aid. 27Turn the syringe upside down. 28Remove the plug from the bottom of the syringe. 29Push the plunger up to the 50 ml mark. 30Attach an Alumicel coalescer cell to the bottom of the syringe. 31Place the syringe in the syringe drive. 32Place a drip pan under the syringe to collect the unwanted portion of the fuel. 33You will hear 4 short tones. If necessary, adjust the meter to read 100 by using the UP (↑) or DOWN (↓) ARROW switch. 34Remove the vial from the turbidimeter well. 35Discard the fuel and drain the vial. 36 A pulsed tone will sound indicating when to collect the last 15 ml of test fuel. Tilt the vial at a slight angle and allow the fuel to flow down the inner surface of the vial. 37Place the vial in the turbidimeter well. 38Align the black mark on the vial with the white mark on the front panel.
