Standard Practice for Evaluating the Compatibility of Additives with Aviation-Turbine Fuels and Aircraft Fuel System Materials

SIGNIFICANCE AND USE
Additives are generally used to enhance a fuel property such as oxidation stability or to improve fuel performance by providing corrosion inhibition, protection against icing, metal deactivation, and so forth. However, their use can adversely affect other fuel properties or the ground-handling systems for fuels. Application of the procedures of this practice is intended to disclose these adverse effects.
Combinations of additives may exhibit antagonistic effects on fuel properties or performance. Compatibility testing with previously approved additives is intended to disclose such antagonistic effects of incompatibilities.
Fuel system components such as sealants, coatings, and elastomers are normally selected because of their resistance to a Reference Test Fluid, which is designed to be more severe to components than standard fuels. Application of the procedures of this practice is intended to disclose adverse effects of additives beyond the effects of the Reference Test Fluids.
SCOPE
1.1 This practice covers procedures required to determine the compatibility of additives proposed for aviation turbine fuels with both standardized fuels and the materials commonly used in commercial aircraft fuel system construction.
1.2 Satisfactory evidence of compatibility using this practice is required by the ASTM Guidelines for Additive Approval (Research Report D02-1125) for additives specified in Specification D 1655 and also by individual aircraft and engine manufacturers as well as government agencies.
1.3 Compatibility data resulting from these procedures represent only part of the performance information required for additive approval.
1.4 The actual level of acceptance is established by the individual approving groups.
1.5 While efforts are made to maintain the list of fuel system materials to be tested and to keep it current, users of this practice must recognize that these lists are subject to continuing revision to meet the needs of equipment manufacturers.
1.6 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.
