ASTM WK27664

    Work Item: ASTM WK27664 - New Guide for Standard Guide for the Evaluation of New Fuels and New Fuel Additives for use in Aviation Spark-ignition Engines and Associated Aircraft Installations

    (What is a Work Item?)

    Developed by Subcommittee: D02.J0.02 | Committee D02 | Contact Staff Manager

    1. Scope

    1.1.This Guide covers processes and procedures for evaluating alternative fuels or additives for aviation spark-ignition engines and associated aircraft installations from any source or process. The document provides guidance and is not a requirement for approaching the appropriate ASTM committees or subcommittees. This document provides guidance in assessing a fuel or additive properties and its potential for meeting the needs and requirements of spark ignition engine aircraft. It is not to be construed as a certification process for determining whether a fuel meets current aviation gasoline properties or for determining changes to operating limitations. Unless a fuel is 100% drop-in the requirement for additional testing is probable. This Guide provides a cost-and-time efficient method for the sponsor of a new fuel or new fuel additive to determine if the product meets an existing ASTM Specification for the aviation industry requirements on physical, chemical, and fit for purpose properties, and if it does not to request a new one. This may include laboratory, test cell, engine test and/or flight test requirements, and evaluation of effect on engine and aircraft materials and performance. It includes suggestions and information in the areas of: oInteractions with engine and airframe manufacturers, standards organizations, and airworthiness agencies such as the FAA and the EASA. oTesting both materials compatibility and performance requirements. oReporting the results of testing and submitting same to the appropriate ASTM committee for review. oOEM approval procedures. Successfully completing all of the testing recommended in this Guide does not preclude the involved committees and industry representatives from requesting further data.

    There is little or no guidance for a fuel researcher regarding the minimum expected data and properties required from a new fuel. There is also a tendency for development work to occur during the ASTM specification process as technical gaps are identified, delaying the effort.
