ASTM D4308-21

5.1?The generation and dissipation of electrostatic charge in fuel due to handling depend largely on the ionic species present which may be characterized by the rest or equilibrium electrical conductivity. The time for static charge to dissipate is inversely related to conductivity. This test method can supplement Test Method D2624 which is limited to fuels containing static dissipator additive.

1.1?This test method covers and applies to the determination of the rest electrical conductivity of aviation fuels and other similar low-conductivity hydrocarbon liquids in the range from 1 pS/m to 2000 pS/m (see 3.1.2). This test method can be used in the laboratory or in the field.

1.2?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3?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.
