Designation:F249705(Reapproved 2011)1Standard Practice forAbrasion and Scuff Resistance of Inkjet Media by theSutherland Rub Tester1This standard is issued under the fixed designation F2497;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.1NOTERevised the units presentation and added a units statement editorially in October 2011.1.Scope1.1 This practice covers a procedure for determining theabrasion resistance of printed and unprinted inkjet media usingthe Sutherland Rub Tester,or its equivalent,equipped withfull-width rubber pads and using standardized receptors.1.2 This practice is applicable to printed and unprintedinkjet media.1.3 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.1.4 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.2.Referenced Documents2.1 ASTM Standards:2D5264 Practice forAbrasion Resistance of Printed Materialsby the Sutherland Rub Tester3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 abrasion resistanceability of a printed surface toresist mechanical destruction.3.1.2 abrasivenessthe degree to which another materialcan abrade the surface of the test specimen.3.1.3 Ink jet mediarefer to recording elements used by inkjet printers to receive inks.The substrate may be paper,plastic,canvas,fabric,or other ink receptive material.The substratemay,or may not,be coated with an ink receptive layer(s).3.1.4 Microporous ink jet media refer to ink media havingink absorbing microporous layer(s).3.1.5 receptorfilm,paper,or fabric of a specified abrasive-ness onto which coatings(for example,ink or protectivecoating)removed from the specimen are deposited during theabrasion test.An example of a receptor is a fine grade crocuscloth or the backside of the inkjet media being evaluated.3.1.6 scuffnggloss change of ink jet media under appliedpressure.4.Summary of Practice4.1 The inkjet media is mounted on top of the rubber pad onthe Sutherland base and the receptor is cut to fit the 2-lb(0.91-kg)or the 4-lb(1.81-kg)weight(depending on whichone is being used).The receptor is mounted to the weight.Thespecimen is rubbed for a total of approximately 10 cycles(20strokes)at a rate of 43 cycle/min,where a cycle is oneback-and-forth stroke.The number of cycles is preset on theSutherland Timer.The weight is mounted on the Sutherlandand the machine is turned on.The Sutherland will shut offautomatically when the desired number of cycles is completed.4.2 The test specimen is removed from the Sutherland baseand examined for degree of print degradation by measuring thechange in gloss,density,or change in physical appearance.Thereceptor is analyzed for the amount of ink or coating trans-ferred from the specimen.Results are compared to an untestedspecimen.5.Significance and Use5.1 Abrasion resistance is a desirable and sometimes criticalproperty of printed materials.Abrasion damage can occurduring shipment,storage,handling,and end use.The result isa significant decrease in product appearance and legibility ofproduct information.The amount of abrasion damage to aprinted substrate is dependent on shipping conditions,possiblytemperature and humidity,time,and many other variables.Thispractice provides a way of comparing abrasion resistance ofprinted materials under laboratory conditions.1This practice is under the jurisdiction of ASTM Committee F05 on BusinessImaging Products and is the direct responsibility of Subcommittee F05.07 on Ink JetImaging Products.Current edition approved Oct.1,2011.Published March 2012.Originallyapproved in 2005.Last previous edition approved in 2005 as F249705.DOI:10.1520/F2497-05R11e1.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 This practice also can be used to evaluate the relativeabrasion and scuff resistance of printed and unprinted inkjetmedia.5.3 This practice can provide a reasonably simple procedurethat can be used by both the buyer and the seller of printedmaterials to determine if the product offered for sale meetssome predetermined standard for abrasion or scuff resistance.6.Interferences6.1 Since the abrasion resistance of inkjet inks and medi
