Standard Test Method for Hydroperoxide Number of Aviation Turbine Fuels by Voltammetric Analysis

Significance and Use:

This test method is functionally equivalent to Test Method D 3703, which uses an ozone depleting substance, (1,1,2-trichloro-1,2,2-trifluoroethane). The use of an ozone depleting substance precludes U. S. military bases from utilizing Test Method D 3703. This test method and Test Method D 3703 measure the same peroxide species (primarily hydroperoxides) in aviation fuels.

The magnitude of the hydroperoxide number is an indication of the quantity of oxidizing constituents present. Deterioration of fuel results in the formation of hydroperoxides and other oxygen-carrying compounds. The hydroperoxide number measures those compounds that will oxidize potassium iodide.

The determination of the hydroperoxide number of fuels is significant because of the adverse effect of hydroperoxides upon certain elastomers in the fuel systems.

Scope:

1.1 The test method covers the determination of the hydroperoxide content of aviation turbine fuels. The test method may also be applicable to the determination of the hydroperoxide content of any water-insoluble, organic fluid, particularly diesel fuels, gasolines, and kerosines.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.3-6.5, Annex A1, and Annex A2.
