1、Designation: D7826 18a An American National StandardStandard Guide forEvaluation of New Aviation Gasolines and New AviationGasoline Additives1This standard is issued under the fixed designation D7826; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This guide provides procedures to develop data for usein research reports for new aviat
3、ion gasolines or new aviationgasoline additives.1.2 This data is intended to be used by the ASTM subcom-mittee to make a determination of the suitability of the fuel foruse as an aviation fuel in either a fleet-wide or limited capacity,and to make a determination that the proposed properties andcrit
4、eria in the associated standard specification provide thenecessary controls to ensure this fuel maintains this suitabilityduring high-volume production.1.3 These research reports are intended to support thedevelopment and issuance of new specifications or specifica-tion revisions for these products.
5、 Guidance to develop ASTMInternational standard specifications for aviation gasoline isprovided in Subcommittee J on Aviation Fuels OperatingProcedures, Annex A6, “Guidelines for the Development andAcceptance of a New Aviation Fuel Specification for Spark-Ignition Reciprocating Engines.”1.4 The proc
6、edures, tests, selection of materials, engines,and aircraft detailed in this guide are based on industryexpertise to give appropriate data for review. Because of thediversity of aviation hardware and potential variation infuel/additive formulations, not every aspect may be encom-passed and further w
7、ork may be required. Therefore, additionaldata beyond that described in this guide may be requested bythe ASTM task force, Subcommittee J, or Committee D02upon review of the specific composition, performance, or othercharacteristics of the candidate fuel or additive.1.5 While it is beyond the scope
8、of this guide, investigationof the future health and environmental impacts of the newaviation gasoline or new aviation gasoline additive and therequirements of environmental agencies is recommended.1.6 The values stated in SI units are to be regarded asstandard.1.6.1 ExceptionSome industry standard
9、methodologiesutilize imperial units as their primary system (permeability;Table A2.1).1.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environme
10、ntal practices and deter-mine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,
