Designation:D163006(Reapproved 2012)Standard Test Method forRubber PropertyAbrasion Resistance(Footwear Abrader)1This standard is issued under the fixed designation D1630;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 Department of Defense.1.Scope1.1 This test method covers the determination of the resis-tance to abrasion of vulcanized rubber,or other rubber mate-rials that are similar to the standard reference compound,usedfor the soles and heels of footwear.It is not recommended formaterials less than 2.5 mm(0.1 in.)in thickness.1.2 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1349 Practice for RubberStandard Temperatures forTestingD2240 Test Method for Rubber PropertyDurometer Hard-nessD4483 Practice for Evaluating Precision for Test MethodStandards in the Rubber and Carbon Black ManufacturingIndustries3.Significance and Use3.1 It is recognized that when comparing different types ofrubber materials,the service performance may not correlate tothe results of this predictive test.3.2 This test method should not be used as a measure ofabrasion resistance for compositions that differ markedly fromthe standard reference compound.Misleading results,forexample,are obtained from polyurethane compositions whencompared with the standard reference compound.3.3 Some specimens may bounce(chatter)against the abra-sive paper,producing inaccurate results.These should beinterpreted with care and the condition reported.3.4 If test results are inconsistent,the specimens should becut,after the test is run,and inspected for voids.If any voidsare present,the results should be disregarded and the testrepeated using test specimens that are free from voids.4.Test Conditions4.1 Unless otherwise specified,the standard temperature fortesting shall be 23 6 2C(73.4 6 3.6F),or the standard testtemperature according to Practice D1349.4.2 Humidity affects the abrasive paper;therefore,therelative humidity shall be controlled at 50 6 5%for at least24 h prior to and during testing.4.3 The specimens shall be conditioned at this temperatureand humidity for no less than 24 h prior to testing.5.Apparatus5.1 Abrasion MachineThe footwear abrader,often re-ferred to as the National Bureau of Standards(NBS)model,isshown in Fig.1 and consists of the following components:5.1.1 Metal Drum,rubber-coated or metal-surfaced,150 mm(6 in.)in diameter.The drum is rotated at a rate of 5.76 0.6 rad/s(45 6 5 rpm)by means of an electric motor.Thenumber of revolutions of the drum is indicated by either adigital or analog counter.5.1.2 Arms,three,each pivoted at one end and having amass suspended from the other end.The mass is attached sothat a force of 22 N(5 lbf)is exerted directly on the specimenin contact with the abrasive paper.5.1.3 Thickness Gauges,three,either digital or analog andgraduated to indicate in increments of no more than 0.02 mm(0.001 in.),attached to a bridge so that each gauge contactseach arm at a point directly over the specimen.The bridge ishinged at one end to allow the arms to swing back for mountingthe specimen.5.1.4 Compressed Air,filtered to be free of moisture andcontaminants,for cleaning the surface of the abrasive paper.1This test method is under the jurisdiction of ASTM Committee D11 on Rubberand is the direct responsibility of Subcommittee D11.15 on Degradation Tests.Current edition approved May 1,2012.Published May 2012.Originallyapproved in 1961.Last previous edition approved in 2006 as D1630 06.DOI:10.1520/D1630-06R12.2For 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 The air is delivered to a manifold or nozzle where the pressureshall be maintained at 210 6 35 kPa(30 6 5 psi).5.1.5 It is recommended to use a suitable suction or vacuumdevice to remove abraded particles during the test.5.1.6 Arm Stop,one for each arm.5.1.7 Rubber Bands or Metal Clamps,for holding the stripof abrasive paper in position around the rotating drum.Theends of the abrasive paper are cut at an angle of about 80 tothe length of the paper and,when in place,permit a clearance(gap)of
