Designation:D58410(Reapproved 2018)Standard Test Method forWool Content of Raw WoolLaboratory Scale1This standard is issued under the fixed designation D584;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 This test method covers a laboratory procedure for thedetermination of the wool base content and the clean wool fiberpresent in samples of raw wool.This test method is alsoapplicable to other animal fibers such as mohair,cashmere,alpaca,and camel hair.NOTE1Sampling of lots of raw wool in packages is covered inPractice D1060;the determination of vegetable matter and other alkali-insoluble impurities in scoured wool is covered in Test Method D1113;thedetermination of wool content on a commercial scale is covered in TestMethod D1334.For factors for the conversion of woolbase content to itsequivalent in terms of scoured wool,top,or noil of various commerciallyspecified compositions(formerly covered in the appendix of this testmethod),refer to Practice D2720.NOTE2Because of the trade practice the term weight is used in thistest method instead of the technically correct term mass.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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 environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 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:2D123 Terminology Relating to TextilesD1060 Practice for Core Sampling of Raw Wool in Packagesfor Determination of Percentage of Clean Wool FiberPresentD1113 Test Method for Vegetable Matter and Other Alkali-Insoluble Impurities in Scoured WoolD1334 Test Method for Wool Content of Raw WoolCommercial Scale(Withdrawn 2018)3D2525 Practice for Sampling Wool for MoistureD2720 Practice for Calculation of Commercial Weight andYield of Scoured Wool,Top,and Noil for Various Com-mercial CompositionsD4845 Terminology Relating to WoolE337 Test Method for Measuring Humidity with a Psy-chrometer(the Measurement of Wet-and Dry-Bulb Tem-peratures)2.2 Other Standard:IWTO-19-85(E)Method for the Determination of WoolBase,Vegetable Matter Base;IWTO Clean Wool Content;IWTO Scoured Yield in Raw Wool43.Terminology3.1 For all terminology relating to D13.13,Wool and WoolFelt,refer to Terminology D4845.3.1.1 The following terms are relevant to this standard:clean wool fiber present,other alkali-insoluble impurities,oven-dried,raw wool,vegetable matter base,vegetable matterpresent,wool base,yield.3.2 For definitions of other textile terms used in this testmethod,refer to Terminology D123.4.Summary of Test Method4.1 The entire sample,or each test specimen drawn there-from in a specified manner,is weighed,scoured,dried,andreweighed.The oven-dry scoured wool is tested to determineits content of alcohol-extractable matter,mineral matter(ash),vegetable matter base,and other alkali-insoluble impurities.The wool-base content,laboratory scoured yield,clean woolfiber present,and vegetable matter present are calculated aspercentages of the mass of the raw wool sample.1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.13 on Wool and Felt.Current edition approved July 1,2018.Published July 2018.Originally approvedin 1940.Last previous edition approved in 2010 as D584 10.DOI:10.1520/D0584-10R18.2For 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.4Specifications of Test Methods,International Wool Textile Organization,International Wool Secretariat,Ilkley,West Yorkshire,U.K.LS298PB.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 5.Significance and Use5.1 T
