Designation:D425289(Reapproved 2017)Standard Test Methods forChemical Analysis of Alcohol Ethoxylates and AlkylphenolEthoxylates1This standard is issued under the fixed designation D4252;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.Scope1.1 These test methods cover the various test methods usedto evaluate those properties pertinent to the characterization ofalcohol ethoxylates and alkylphenol ethoxylates with respect tosuitability for desired uses.1.2 The procedures for sampling and analysis appear in thefollowing order:SectionsSamplingLiquids6Solids7Methods of Chemical AnalysisWater or moisture8Refractive index9 and 10pH11Acidity or basicity12 and 13Hydroxyl number14 20Cloud point21Iodine number22Ash23Iron24Ethylene oxide content25Polyethylene glycols26 321.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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.Material SafetyData Sheets are available for reagents and materials.Reviewthem for hazards prior to usage.Specific hazard statementsappear in Section 5 and Note 1 and Note 3.2.Referenced Documents2.1 ASTM Standards:2D459 Terminology Relating to Soaps and Other DetergentsD482 Test Method for Ash from Petroleum

cleaners.1These test methods are under the jurisdiction of ASTM Committee D12 onSoaps and Other Detergents and are the direct responsibility of SubcommitteeD12.12 on Analysis and Specifications of Soaps,Synthetics,Detergents and theirComponents.Current edition approved Jan.1,2017.Published February 2017.Originallyapproved in 1983.Last previous edition approved in 2009 as D4252 89(2009).DOI:10.1520/D4252-89R17.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright 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 International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 They may be used as either nonionic surfactants or sulfated andused as anionic surfactants.Careful control of the ethoxylatecharacteristics is desired as variations may result in eitherdesirable or undesirable end-use properties.4.Purity of Reagents4.1 Reagent-grade chemicals shall be used in all tests.Unless otherwise indicated,it is intended that all reagents shallconform to the specifications of the Committee on AnalyticalReagents of the American Chemical Society,where suchspecifications are available.4Other grades may be used,pro-vided it is first ascertained that the reagent is of sufficientlyhigh purity to permit its use without lessening the accuracy ofthe determination.4.2 Unless otherwise indicated,references to water shall beunderstood to mean Type III reagent water conforming toSpecification D1193.5.Safety Precautions5.1 All reagents and chemicals should be handled with care.Before using any chemical,read and follow a
