1.1 This practice determines suitability of products used for measuring particulate contamination in aviation turbine fuel when using Test Methods D5452 and D2276.

1.2 There are two major parts of this practice. The first is for evaluation of the cellulose acetate butyrate field monitors that are used in combination with the filters and the filter support pads. The second part is for evaluation of the filter when used with an appropriate cellulose acetate butyrate field monitor.

1.3 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 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.

5.1 This practice provides criteria for products used to measure particulate matter present in a sample of aviation turbine fuel. The objective is to verify that filters, support pads, and field monitors fall within the acceptable ranges that are established by this practice.
