1.1 This test method covers two procedures for establishing the presence of suspended free water, solid particulate, and other contaminants in aviation gasoline and aviation turbine fuels.
1.1.1 Both procedures are intended primarily for use as field tests with the fuel at handling temperature.
1.1.2 Procedure A uses transparent sample containers; Procedure B uses opaque containers.
1.2 Both procedures are rapid methods for contamination detection and include ratings of haze appearance and particulate presence.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
