5.1 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 purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take test specimens that are from the lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using student's t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be 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, it may be desirable to 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-out may be due to abrasive action on either the face or back. With many pile fabrics, specifically corduroy constructions, pile retention properties are worse when abraded on the back. |

1.1 This test method covers the determination of the abrasion of pile fabrics when the loss of pile tuffs occur, sometimes called pile retention or pile pull out. It includes two procedures: 1.1.1 Procedure A—The “Heavy Duty” procedure describes the test option for fabrics over 240 g/m2 (7 oz/yd2) or fabrics which should meet heavy duty end-use conditions of wear. 1.1.2 Procedure B—The “Light Duty” procedure describes the test option for fabrics under 240 g/m2 (7 oz/yd2) or fabrics which should 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 stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
