Electrical Conductivity of Aviation and Distillate Fuels

This standard has been approved for use by agencies of the Department of Defense.

EMCEE MODELS 1152 and 1153 Digital Conductivity Meters - self- contained, portable, hand held, used for static measuring of the electrical conductivity of a product sample.

EMCEE MODEL 1150 Staticon System - dynamically monitors and controls the electrical conductivity level of a product in a pipeline.

1. Scope*

1.1 These test methods cover the determination of the electrical conductivity of aviation and distillate fuels with and without a static dissipator additive. The test methods normally give a measurement of the conductivity when the fuel is uncharged, that is, electrically at rest (known as the rest conductivity).

1.2 Two test methods are available for field tests of fuel conductivity. These are: (1) portable meters for the direct measurement in tanks or the field or laboratory measurement of fuel samples, and (2) in-line meters for the continuous measurement of fuel conductivities in a fuel distribution system. In using portable meters, care must be taken in allowing the relaxation of residual electrical charges before measurement and in preventing fuel contamination.

1.3 The values stated in SI units are to be regarded as 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 and health practices and determine the applicability of regulatory limitations prior to use.
