Active Standard: D7111 - 11
The method is being revised to add six additional elements (P, Sn, Sr, Pt, Pd, Co) to the existing list of elements that can be determined by D7111. This work was done at the request of Subcommittee D02.J0.06 on Emerging Turbine Fuels, to provide an alternative analysis method to the use of UOP389 which is listed in Standard Specification D7566 on Aviation Turbine Fuel Containing Synthesized Hydrocarbons. Because UOP 389 is no longer generally available (due to safety concerns and availability of required reagents), it is critical for Sub J to have an alternative method in a timely manner. This ballot adds an interim precision statement based on an initial ILS of the six elements (there were insufficient DF for several of the elements, therefore further work will be done to determine a final precision statement through a future ILS).
