2、 last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1 NOTEThe Terminology section was updated in June 2011.1. Scope1.1 This test method covers the determination of the abrasion of p
3、ile fabrics when the loss of pile tuffs occur, sometimes calledpile retention or pile pull out. It includes two procedures:1.1.1 Procedure AThe “Heavy Duty” procedure describes the test option for fabrics over 240 g/m2 (7 oz/yd2) or fabrics whichshould meet heavy duty end-use conditions of wear.1.1.
4、2 Procedure BThe “Light Duty” procedure describes the test option for fabrics under 240 g/m2 (7 oz/yd2) or fabrics whichshould meet light duty end-use conditions of wear.1.2 The test method is intended for both regular, ribless woven corduroy or other woven pile fabric constructions.1.3 The values s

The values statedin each system may not be exact equivalents; therefore, each system shall be used independently of the other.

United States14. Summary of Test Method4.1 Test s
16、pecimens are exposed to a specified number of abrasion cycles on face and back separately and then evaluated byviewing the specimen over a light box and comparing to photographic standards. The method measures only the amount of pilepulled out of the base fabric structure and not the surface pile ap
17、pearance attributes, such as crushed or flatten ribs.5. Significance and Use5.1 This test method is considered satisfactory for quality control testing and commercial shipment acceptance.5.1.1 In case of a dispute arising from differences in reported test results when using this test method, the pur
18、chaser and thesupplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statisticalassistance is recommended for the investigation of bias. As a minimum, the two parties should take test specimens that are fromthe lot of material of t
19、he type in question. The test specimens should then be randomly assigned in equal numbers to eachlaboratory for testing. The average results from the two laboratories should be compared using students t-test for unpaired dataand an acceptable probability level chosen by the two parties before the te
20、sting is begun. If a bias is found, either its cause mustbe found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.5.2 Finishes and changes in fabric surfaces may exert a large effect on pile retention of corduroy. Therefore,
21、it may be desirableto test before as well as after laundering or drycleaning, or both.5.3 The separate testing of specimens on the face and back of the fabric is important in this test method since the pile pull-outmay be due to abrasive action on either the face or back. With many pile fabrics, spe
22、cifically corduroy constructions, pile retentionproperties are worse when abraded on the back.6.

46、carefully onto the surface of the specimen.12.4 Lower the vacuum suction nozzle and adjust it to approximately 6.35 mm (14 in.) above the specimen. Failure to adjustthe nozzle to the fabric thickness can cause excess abrasion if the nozzle is leftpositioned too low.12.5 Adjust the vacuum suction con

48、 100 cycles. Use CS-10 wheels with a loading mass of 500 g/wheel.12.6.2 Option B Light Duty ProcedureTest two specimens on the fabric face for 300 cycles and two specimens on the backfor 50 cycles. Use CS-10 wheels with a loading mass of 250 g/wheel. (Each arm minus the auxillaryauxilliary weights e
49、quals 250g/wheel.)12.7 After testing, raise wheels and vacuum nozzle then remove the specimen for grading. If desired, the holder may beremoved from the tester by lifting straight up. This will permit a closer inspection of the specimen prior to removal from the holder.NOTE 2For special studies when a transparent platform to the specimen holder is used, pile loss may be observed over the viewing box with thespecimen still attached to the transparent holder.13.
