Summary of Test Method4.1 This test method provides procedures for preparingcylindrical test pieces of specified dimensions from vulcanizedthermoset rubbers or thermoplastic elastomers and
23、for evalu-ating their abrasion resistance by sliding a test piece across thesurface of an abrasive sheet5attached to a rotating drum. It alsodescribes the preparation and compliance testing of a StandardRubber (see Annex A1).4.2 The test is performed under specified conditions ofcontact pressure, sl
24、iding distance, and travel speed of the testpiece, rotational speed of the drum, and degree of abrasivenessof the abrasive sheet.4.3 The abrasiveness, S, of the abrasive sheet is defined bythe mass loss in milligrams of a test piece prepared fromStandard Rubber #1 when tested under the same specifie
25、dconditions.4.4 Four different methods may be used to test the abrasionresistance. Method A, uses a non-rotating test piece andMethod B a rotating test piece, both utilizing Standard Rubber#1 as the reference. Methods C and D use Standard Rubber #2as reference with a non-rotating and rotating test p
26、iece,respectively. The rotating test pieces provide, in many cases, amore uniform abrasion wear pattern.4.5 The abrasion resistance, AA, obtained in accordance withMethod A is reported as abrasion (volume) loss in cubicmillimetres, calculated from the mass loss of the test piece,density of the test
27、rubber, and the abrasiveness of the abrasivesheet in relation to the “nominal abrasiveness” (S0) defined bya mass loss of 200 mg. A smaller number indicates a higherresistance to abrasion.4.6 The abrasion resistance, ARIAD, obtained in accordancewith Methods A, B, C, and D is reported as the abrasio
28、nresistance index in percent, calculated from the mass losses anddensities of the Standard Rubbers and test rubbers. A smallernumber indicates a lower resistance to abrasion.4.7 The mass loss obtained by the different methods candiffer and the same method shall therefore be used if mass (andvolume)
29、losses are to be compared directly.5. Significance and Use5.1 Abrasion resistance is a performance factor of para-mount importance for many rubber products, such as tires,conveyor belts, power transmission belts, hoses, footwear, andfloor covering. A test capable of measuring resistance toabrasion o
30、f rubber, including uniformity of wear behaviorunder abrasive/frictional service conditions is therefore highlydesirable.5.2 This test method may be used to estimate the relativeabrasion resistance of different rubbers. Since conditions ofabrasive wear in service are complex and vary widely, no dire
31、ctcorrelation between this accelerated test and actual perfor-mance can be assumed.5.3 This test method is suitable for comparative testing,quality control, specification compliance testing, refereepurposes, and research and development work.6. Limitations6.1 Test pieces containing voids or porosity
32、, or both, willyield unreliable test results.6.2 Test pieces that bounce (chatter) over the surface of theabrasive sheet rather than running smoothly will produceinaccurate test results.6.3 Test pieces that tend to extensively smear the surface ofthe abrasive sheet will provide meaningless test resu
33、lts.6.4 Test results obtained under any of the above conditionsshall not be used to reach conclusions regarding the relativeabrasion resistance of rubbers.7.

35、e abrasion tester consists of a machine frameholding a laterally movable test piece holder, a rotary cylin-drical drum to which an abrasive sheet can be fastened, and adrive system as shown in Fig. 1. Dimensions are given in Fig.2.7.1.2 The diameter of the cylindrical drum shall be 150.0 60.2 mm (5.
36、906 6 0.008 in.) and its length approximately 500mm (20 in.), operating at a rotational frequency of 0.11 60.003 rad/s (40 6 1 rpm).7.1.3 The abrasive sheet shall be bonded tightly to the drumusing three evenly spaced double-faced pressure-sensitiveadhesive tapes, extending the full length of the dr
37、um. The tapesshall be about 50 mm (2 in.) wide and not more than 0.2 mm(0.008 in.) thick. The gap where the ends of the abrasive sheetsmeet on the adhesive tapes shall not exceed 2 mm (0.08 in.).7.1.4 It is mandatory that the abrasive sheet is bonded to thedrum in the direction of rotation marked on
38、 the surface or backof the sheet.7.1.5 The test piece holder shall be mounted on a pivotedswivel arm, which can be swung into vertical position to insertand remove the test piece (see Note 2).NOTE 2It is recommended to install a device preventing the test pieceholder and abrasive sheet from coming i
39、nto contact and damaging eachother.7.1.6 Suitable attachments may be provided to rotate the testpiece around its own axis during the test run by rotation of thetest piece holder (Methods B and D). The test piece shall rotateat the rate of 1 revolution for each 50 revolutions of thecylindrical drum w
40、ith the abrasive sheet fastened to the drum.7.1.7 The center axis of the test piece holder shall have anangle of 3 to the perpendicular in the direction of rotation andthe center of the test piece shall be within 61mm(60.04 in.)directly above the longitudinal axis of the drum.7.1.8 The design of the
41、 swivel arm and holder shall be suchthat the test piece is pressed against the abrasive sheet with aforce of 10.0 6 0.2 N (2.25 6 0.04 lbf). Both swivel arm andholder shall be free from vibration during operation.7.1.9 The test piece holder shall consist of a cylindricalopening with an adjustable di
42、ameter of at least 15.5 mm (0.610in.) to 16.3 mm (0.642 in.) and a device for adjusting the lengthof the test piece protruding from the opening to 2.0 6 0.2 mm(0.08 6 0.008 in.).7.1.10 The swivel arm with the test piece holder is con-nected to a worm gear that moves the holder on a guide rodlaterall
43、y across the surface of the abrasive sheet attached to thecylindrical drum. The lateral displacement shall be approxi-mately 4.2 mm (0.165 in.) per revolution of the drum, so thatthe test piece passes only four times across the same area of thesheet during one test cycle.7.1.11 Placement of the hold
44、er with the test piece on thedrum at the beginning of the test and removal at the end shallbe automatic. The normal length of the abrasion path shall be40.0 6 0.2 m (131.2 6 0.7 ft). This is equivalent to about 84revolutions when allowing for the thickness of 1 mm (0.04 in.)for the abrasive sheet.7.
45、1.12 For special cases of very high volume loss, half thelength of the abrasion path, that is, 20 6 0.1 m (65.6 6 0.3 ft),equivalent to roughly 42 revolutions, may be used.7.1.13 The test machine may be equipped with a vacuumhose and a brush that contacts the drum and aids in the removalof debris.7.
46、2 Abrasive Sheet:7.2.1 Corundum (aluminum oxide) of grit 60 bonded to acarrier sheet of at least 400 mm (15.8 in.) width, 474 6 1mm(18.66 6 0.04 in.) length and an average thickness of 1 mm(0.04 in.) shall be used as the abrasive medium.7.2.2 The sheets shall be of an abrasiveness as to cause amass
47、loss between 180 and 220 mg when tested over anabrasion path of 40 m (131.2 ft) using a non-rotating test piece(Method A) of Standard Rubber #1 specified in Section 8.7.2.3 Since the abrasiveness of virgin abrasive sheets isusually higher than desired, it is necessary to blunt the sheetswith one or
48、two test runs using a steel test piece in place of theStandard Rubber to bring it into the desired range. Thedirection of rotation used for blunting shall be marked on thesheets.7.2.4 After blunting, the abrasive sheets shall be thoroughlycleaned by brushing, blowing, or suction and two test runs wi
49、ththe Standard Rubber shall be made.FIG. 1 Abrasion TesterFIG. 2 Side View and Dimensions of Abrasion TesterD5963 04 (2010)137.2.5 Test results obtained with abrasive sheets, thuscalibrated, are more consistent, and it is normally possible torun several hundred single tests using the same sheet.7.3 Rotating Test Specimen Cutting Die:7.3.1 The rotating cutting die for specimen preparation is ofa hollow drill configuration, manufactured from A2 or P2grade steel having a hardness of HRC 50, or above, of thedimensions shown in Fig. 3.7.3.2 The
