The United States Army conducted several laboratory evaluations of automatic light obscuration particle counters to develop limits for aviation fuel cleanliness. The laboratory evaluations concluded an ISO code limit, based on ISO 4406, of 19171413 limits for the 4mc 6m c 14m c 30m c size channels derived from 1.0 mgL concentration levels for ISO 12103-1 A1 Ultrafine and ISO 12103-1 A2 Fine test dusts, and down to a 5 ppm free water contamination was the best technical solution for applying this technology to fuel applications.
