Designation:D441817Standard Practice forReceipt,Storage,and Handling of Fuels for Gas Turbines1This standard is issued under the fixed designation D4418;the number immediately following the designation indicates the year oforiginal adoption or,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 practice covers the receipt,storage,and handling offuels for gas turbines,except for gas turbines used in aircraft.It is intended to provide guidance for the control of substancesin a fuel that could cause deterioration of either the fuel system,or the gas turbine,or both.1.2 This practice provides no guidance for either the selec-tion of a grade of fuel,a topic covered by Specification D2880,or for the safety aspects of the fuel and fuel systems.Forexample,this practice does not address the spacings of storagetanks,loading and unloading facilities,etc.,and procedures fordealing with the flammability and toxic properties of the fuels.1.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.4 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 and health practices and determine the applica-bility of regulatory limitations prior to use.1.5 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,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D1500 Test Method for ASTM Color of Petroleum Products(ASTM Color Scale)D1796 Test Method for Water and Sediment in Fuel Oils bythe Centrifuge Method(Laboratory Procedure)D2274 Test Method for Oxidation Stability of Distillate FuelOil(Accelerated Method)D2276 Test Method for Particulate Contaminant in AviationFuel by Line SamplingD2880 Specification for Gas Turbine Fuel OilsD4057 Practice for Manual Sampling of Petroleum andPetroleum ProductsD6469 Guide for Microbial Contamination in Fuels and FuelSystems3.Terminology3.1 Definitions:3.1.1 fuel entering the combustor(s)this term is used todesignate the fuel that is actually burned in the gas turbine.Fuel may actually be sampled at a point upstream from thepoint of entry into the combustor(s),provided the sample isrepresentative of the fuel actually entering the combustor(s).3.1.2 fuel contaminant,nmaterial not intended to bepresent in a fuel,whether introduced during manufacture,handling,distribution,or storage,that makes the fuel lesssuitable for the intended use.3.1.2.1 DiscussionContaminants,which can be soluble inthe fuel or insoluble(suspended liquid droplets or solid orsemi-solid particles),can be the result of improper processingor contamination by a wide range of materials including water,rust,airblown dust,deterioration of internal protective coatingson pipes or vessels,and products of fuel degradation andmicrobial growth.3.1.2.2 DiscussionSolid or semisolid contaminants can bereferred to as silt or sediment.3.1.3 dissolved and free water,nwater may be present inthe fuel as dissolved water or as“free”(undissolved)water,orboth.The free water may be fresh or saline.Fresh water mayenter the fuel from steam coils in storage tanks,from conden-sation out of moisture-laden air,or from leaking cooling coils.Saline water can enter the fuel during transportation in bargesor tankers.3.1.4 particulate solids,nmay enter a fuel from the air(suspended dirt and aerosols)or from the distribution andstorage systems(rust,corrosion products,gasket debris,and soforth).3.1.5 metallic compounds,nmetals may be present asmetallic compounds in the fuel as a natural result of the1This practice is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.E0 on Burner,Diesel,Non-Aviation Gas Turbine,and Marine Fuels.Current edition approved May 1,2017.Published May 2017.Originallyapproved in 1984.Last previous edition approved in 2016 as D4418 00(2016).DOI:10.1520/D4418-17.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of In
