The United States Army conducted a survey of over 1700 fuel samples with the objective of evaluating the proposed limits for use by automatic light obscuration particle counters for the monitoring of aviation fuel cleanliness. The laboratory data collected supports the proposed ISO code limit, based on ISO 4406, of 19171413 limits for the 4mc6m c 14m c 30m c size channels. The proposed limits were derived from 1.0 mgL concentration levels for ISO12103-1 A1Ultrafine and ISO 12103-1 A2 Fine test dusts, and down to a 5 ppm free water contamination.
