1、Designation: D7826 17D7826 17a 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,

2、 in the 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 use in research reports for

3、new aviation gasolines or new aviationgasoline additives.1.2 This data is intended to be used by the ASTM subcommittee to make a determination of the suitability of the fuel for useas an aviation fuel in either a fleet-wide or limited capacity, and to make a determination that the proposed propertie

4、s and criteriain the associated standard specification provide the necessary controls to ensure this fuel maintains this suitability duringhigh-volume production.1.3 These research reports are intended to support the development and issuance of new specifications or specification revisionsfor these

5、products. Guidance to develop ASTM International standard specifications for aviation gasoline is provided inSubcommittee J on Aviation Fuels Operating Procedures, Annex A6, “Guidelines for the Development and Acceptance of a NewAviation Fuel Specification for Spark-Ignition Reciprocating Engines.”1

6、.4 The procedures, tests, selection of materials, engines, and aircraft detailed in this guide are based on industry expertise togive appropriate data for review. Because of the diversity of aviation hardware and potential variation in fuel/additive formulations,not every aspect may be encompassed a

7、nd further work may be required. Therefore, additional data beyond that described in thisguide may be requested by the ASTM task force, Subcommittee J, or Committee D02 upon review of the specific composition,performance, or other characteristics of the candidate fuel or additive.1.5 While it is bey

8、ond the scope of this guide, investigation of the future health and environmental impacts of the new aviationgasoline or new aviation gasoline additive and the requirements of environmental agencies is recommended.1.6 The values stated in SI units are to be regarded as standard.1.6.1 ExceptionSome i

9、ndustry standard methodologies utilize imperial units as their primary system (permeability; TableA2.1).1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety safe
