Standard Test Method for Estimation of Hydrogen Content of Aviation Fuels

SCOPE
1.1 This test method covers the estimation of the hydrogen content (mass percent) of aviation gasolines and aircraft turbine and jet engine fuels.  
1.2 This test method is empirical and is applicable to liquid hydrocarbon fuels that conform to the requirements of specifications for aviation gasolines or aircraft turbine and jet engine fuels of types Jet A, Jet A-1, Jet B, JP-4, JP-5, JP-7, and JP-8.  Note 1-The procedure for the experimental determination of hydrogen in petroleum fractions is described in Test Methods D1018 and D3701. Note 2-The estimation of the hydrogen content of a hydrocarbon fuel is justifiable only when the fuel belongs to a well-defined class for which a relationship among the hydrogen content and the distillation range, density, and aromatic content has been derived from accurate experimental measurements on representative samples of that class. Even in this case, the possibility that the estimates may be in error by large amounts for individual fuels should be recognized. The fuels used to establish the correlation presented in this method are defined by the following specifications: Fuel Specification Aviation gasolines D910 Aircraft turbine and jet engine fuels JP-4 and JP-5 MIL-T-5624 JP-6 MIL-J-25056 (Obsolete) JP-7 MIL-T-38219 Jet A D1655 Miscellaneous hydrocarbons No. 2 Diesel fuel Kerosine distillates (similar to Jet A) Miscellaneous (includes thinners, gasoline fractions, and unidentified blends) Special production fuels (commercial products of nearly pure hydrocarbons and special high-temperature fuels (HTF) produced for Air Force tests. Pure hydrocarbons
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address 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.
