1、Designation: D3389 10Standard Test Method forCoated Fabrics Abrasion Resistance (Rotary PlatformAbrader)1This standard is issued under the fixed designation D3389; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last re
2、vision. 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
3、 the wearresistance of fabrics coated with rubber or plastics to abrasion.The abrasion is measured by mass loss or number of cyclesrequired to wear through the coating to initially expose the basefabric.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parenthe
4、ses 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

Summary of Test Metho
6、d3.1 Abrasion resistance of fabrics coated with rubber orplastics is measured by subjecting the specimen to the rotary-rubbing action of two abrasive wheels under controlled condi-tions of pressure by the use of the rotary platform abrader. Thetest specimen, mounted on a turntable platform, turns on
7、 avertical axis against the sliding rotation of two abradingwheels. One abrading wheel rubs the specimen outward towardthe periphery and the other, inward toward the center. Theresulting abrasion marks form a circular pattern of crossed arcsover an area of approximately 30 cm2.4. Significance and Us
8、e4.1 Abrasion resistance tests are intended to measure thewear resistance properties of a material. This may be correlatedto expected end use performance.5. Apparatus5.1 Abrasion Apparatus,3comprised of a removable flatcircular specimen holder, a pair of pivoted arms to which theabrasive wheels are
9、attached, a motor for rotating the specimenholder, a vacuum unit and nozzle for removal of abradedparticles during test, and a counter for indicating the revolu-tions of the specimen holder. See Fig. 1.5.1.1 The specimen holder shall be mounted to produce acircular surface travel of an essentially f
10、lat specimen in theplane of its surface at a uniform angular velocity.5.1.2 A clamping ring shall be used to secure the specimento the specimen holder.5.1.3 The abrasive wheels, which are attached to the freeend of independently pivoted arms, shall rotate and have, whenresting on the specimen, a per
11、ipheral engagement with thesurface of the specimen, the direction of travel of the peripheryof the wheels and of the specimen at the contacting portionsbeing at acute angles, and the angle of travel of one wheelperiphery being opposite to that of the other. Motion of theabrasive wheels, in opposite
12、directions, shall be provided byrotation of the specimen and the associated friction therefrom.5.1.4 The apparatus shall be provided with a vertical-forceadjustment (auxiliary masses) for varying the vertical force ofthe abrader wheels on the specimen. The pivoted abrader armswithout auxiliary masse
13、s or counterweights shall apply avertical force against the specimen of 2.45 N (250 gf) perwheel. Auxiliary masses may be used to apply a vertical forceagainst the specimen of 4.9 N (500 gf) per wheel or 9.8 N1This test method is under the jurisdiction of ASTM Committee D11 on Rubberand is the direc

20、ive tests on eachsample of coated fabrics.6.2 Cut circular test specimens approximately 110 mm (412in.) in diameter. Punch or drill a 6-mm (14-in.) hole in thecenter of the specimen. Take care in cutting out specimens. Usethe best portion of the sample to be tested. It should be free ofholes, bliste

If no wheel is specified,the H-18 vitrified wheel or equivalent is recommended.NOTE 2Abrasion tests utilizing the rotary platform abrader may besubject to variation due to the changes in the abradant during the courseof the test. Depen
24、ding on abradant type and test specimen, the abradingwheel surface may change (that is, become clogged) due to the pick-up ofworn materials from test specimens. To reduce this variation, the abradingwheels should be resurfaced according to the manufacturers recommen-dations.8.2 Determine the origina
