2 2 Pass/Fail Limits Contaminant limit Location Water Particulate Authority Comments Refinery production Distribution system Airport into-storage Clear and bright Clear and bright 1,0 mg/l DEF STAN , JIG AFQRJOS Clear and bright ASTM D ,5 mg/l Kinder Morgan pipeline 1,0 mg/l MIL-DTL (JP8/JP8+100) Contaminant limit No quantitative limit for water US Air Force 1,0 mg/l MIL-DTL-5624 (JP4/JP5) US Navy 2,2 mg/l Canadian GSB Clear and bright 30 ppm 1,0 mg/l IATA Guidance Material After-fuelling check Rejection limit for monthly equipment check Into-plane Clear and bright 0,44 mg/l Canadian GSB ppm (maximum allowable) A2, B2, and G2 (Dry) A3, B3, and G3 (wet) 0,5 mg/l ATA 103 Colorimetric interpretation of a gravimetric membrane

3 3 How can we effectively ensure in field performance qualified filters and systems? Current technology limitations - Monthly Millipore & AquaGlo Spot Check/Sporadic contamination in clean systems Lab work required Delay in obtaining results Sampling integrity issues 1 lt or 5 lt? Time? Burst membranes Subjective testing, lack of real definition Negative results Poor repeatability So: Is particle counting a solution? Can we correlate with existing methods?

4 4 Gravimetric Review Advantages of APC technology or Disadvantages of current methods Current Method Limitations: The eye can only detect particles >40 microns (30 micron(c)) unless present in very large amounts. Gravimetric is not available in real time and sometimes is erratic and is non-informative in terms of condition monitoring. Filtration time requires a laboratory environment. GRAVIMETRIC 1 USG Sample Or at least record the volume that does go through Working Membrane, W Control Membrane, C Both are 1mg/l!!!! Nobody knows where the current contamination limits come from where is the technical justification? Or are they? 0.5mg/l
