Designation:D104419Standard Test Method forResistance of Transparent Plastics to Surface Abrasion bythe Taber Abraser1This standard is issued under the fixed designation D1044;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This test method describes a procedure for estimatingthe resistance of transparent plastics to one kind of surfaceabrasion by measuring the change in optical properties.1.2 Abrasive damage is numerically quantified by calculat-ing the difference in haze percentage in accordance with TestMethod D1003 between an abraded and unabraded specimen.1.3 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.NOTE1This test method is equivalent in the measurement ofresistance to abrasion of ISO 3537,Section 8 and ISO 15082,Section 11,but is not equivalent in any other measurement or section.This testmethod is not equivalent to ISO 9352,and results cannot be directlycompared between the two methods.NOTE2This test method is similar to SAE J3097Z26,Test 12.NOTE3Prior attempts to employ the Taber Abraser for volume lossdeterminations of various plastics2have been unsuccessful because ofexcessively large coefficients of variation attributed to the data.Insuffi-cient agreement among the participating laboratories has rendered the useof volume loss procedure inadvisable as an ASTM test method.NOTE4For determining the resistance to abrasion of organic coatingsby weight loss,reference is made to Test Method D4060,which uses moreaggressive CS-10 or CS-17 abrasive wheels.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,health,and environmental practices and deter-mine the applicability 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:3D883 Terminology Relating to PlasticsD1003 Test Method for Haze and Luminous Transmittanceof Transparent PlasticsD4000 Classification System for Specifying Plastic Materi-alsD4060 Test Method for Abrasion Resistance of OrganicCoatings by the Taber AbraserE456 Terminology Relating to Quality and StatisticsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodG195 Guide for Conducting Wear Tests Using a RotaryPlatform Abraser2.2 ISO Standards:4ISO 3537 Road VehiclesSafety Glazing MaterialsMechanical TestsISO 9352 PlasticsDetermination of Resistance to Wear byAbrasive WheelsISO 15082 Road VehiclesTests for Rigid Plastic SafetyGlazing Materials2.3 ANSI Standards:4SAE J3097Z26 Standard for Safety Glazing Materials forGlazing Motor Vehicles and Motor Vehicle EquipmentOperating on Land HighwaysSafety Standard3.Terminology3.1 DefinitionsDefinitions used in this test method are inaccordance with Terminology D883,unless otherwise speci-fied.For terms relating to precision and bias and associatedissues,the terms used in this test method are defined inaccordance with Terminology E456.3.2 Definitions:1This test method is under the jurisdiction of ASTM Committee D20 on Plasticsand is the direct responsibility of Subcommittee D20.10 on Mechanical Properties.Current edition approved Sept.1,2019.Published September 2019.Originallyapproved in 1949.Last previous edition approved in 2013 as D1044-13.DOI:10.1520/D1044-19.2Supporting data are available from ASTM Headquarters.Request RR:D20-48and RR:D20-1090.3For 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.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.*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 International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.2.1 abrasionabrasive wear caused by displaceme
