Designation:D426521Standard Guide forEvaluating Stain Removal Performance in HomeLaundering1This standard is issued under the fixed designation D4265;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 is a guide for evaluating stain removal performanceof home laundry products or home laundering conditions.Itprovides guidance for the selection,preparation,application,and examination of various types of stains on test fabrics thatare subjected to controlled but practical stain removal treat-ment conditions.1.2 There is no single combination of stain and fabric thatwill predict the overall performance of a product or treatmentmethod.A single test,even with a variety of stains/fabrics,canonly predict how products or treatment methods compare underthe particular conditions chosen for evaluations.A series ofassessments is necessary to evaluate the many aspects of stainremoval performance and to simulate consumer experiencemore closely.1.3 In this guide,the use of both traditional top-loaderwashing machines as well as front and top-loading high-efficiency washers is addressed.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 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.1.6 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:2D1729 Practice for Visual Appraisal of Colors and ColorDifferences of Diffusely-Illuminated Opaque Materials2.2 AATCC Standard:3Test Method 130-2010 Soil Release:Oily Stain ReleaseMethod3.Terminology3.1 Definitions:3.1.1 front-loading high-effciency(HE)washing machine/washer,nhorizontally or nearly horizontally oriented ma-chine used for laundry that uses varying amounts of water tolaunder fabrics.3.1.1.1 DiscussionThese washers:(1)may not exhibit anyvisible free water or may show significant quantities of visiblefree water,(2)may lift and tumble the clothes load,(3)may useboth spinning and tumbling in both the washer or rinseprocesses,(4)may use jet sprays of wash solution or rinsesolution,or(5)may use thermal or chemical inputs,or both,tooffer sanitation or allergen claims.HE washers use consider-ably less water and energy than traditional deep-fill washers inthe laundering process.HE washers are labeled by the appli-ance industry and may be recognized by the U.S.Departmentof Energy(DOE)and the U.S.Environmental ProtectionAgency(EPA)as Energy Star rated machines.3.1.2 home laundering,ncleaning or conditioning,orboth,of textile materials using the washing and drying equip-ment commonly found in the home.3.1.3 pretreaters,nusage of a product designed to treatfabric stains not likely to be removed using detergent in washalone in the normal household laundering process.3.1.3.1 DiscussionPretreaters can be found in many forms1This guide is under the jurisdiction of ASTM Committee D12 on Soaps andOther Detergents and is the direct responsibility of Subcommittee D12.15 onPhysical Testing.Current edition approved Jan.15,2021.Published January 2021.Originallyapproved in 1983.Last previous edition approved in 2014 as D4265 14.DOI:10.1520/D4265-21.2For 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.3Available from American Association of Textile Chemists and Colorists(AATCC),P.O.Box 12215,Research Triangle Park,NC 27709,http:/www.aatcc.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.1such as sprays and liquids and detergents themselves can beused as a pretreater when applied directly to the stain.3.1.4 stain,na local area of undesired foreign matter on atextile material,differing in appearance
