Other fabrics with established test values may be used for this purpose. ACT studies indicate that results of multiple abrasion tests performed on some woven fabric structures may vary significantly — as much as 60 percent or more.
Understanding Abrasion Testing
It is not surprising, therefore, to find that there are many different types of abrasion testing machines, abradants, testing conditions, testing procedures, methods of evaluation of abrasion resistance, and interpretation of results. This test method may not be usable for some fabric asmt. Historical Version s – view previous versions of standard. The measurement of the relative amount of abrasion may also be affected by the method of evaluation and may be influenced by the judgment of the operator.
Permanent abradants may also change due to pick up of finishing or other material from test fabrics and must accordingly be cleaned at frequent intervals. Number of cycles determines abrasion rating. Whenever possible all materials that are to be compared with each other should be tested under the same pressure and tension.
Satm, ACT does not recommend using absolute numbers for comparision. For more information please refer to abrasion white papers on the ACT website. Wire screen or wire mesh is used as an abradant when the test specimen is more abrasive than the cotton duck. Within the text, the inch-pound units are shown in parentheses.
For survey details and additional research, read our White Papers. The results obtained from the use of this instrument assist in evaluating these factors relative to the wear serviceability of the final textile product in specific end uses. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Fabrics of all types including carpets, garments and nonwovens may be tested under this method. Other procedures for measuring the abrasion resistance of textile fabrics are given in: This is an oscillating test.
A fabric with twice the number of abrasion cycles does not indicate double the service life. Experience has shown in many instances, that relative results obtained with this instrument when used on a series of fabrics, agreed with those obtained based upon performance in end use.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Association of Contact Textiles Website.
Wyzenbeek — New Test Video. In general, they should not be relied upon for prediction of actual wear-life in specific end uses unless there are data showing the specific relationship between laboratory abrasion tests and actual wear in the intended end-use.
Wyzenbeek results abovedouble rubs have not been shown to be an indicator of increased lifespan. All of the following issues should be included in any such assessment: Historical Version s – view previous versions of standard.
With disposable abradants, the abradant is used only once or changed after limited use. Link to Active This link will always route to the current Active version of the standard.
The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. This test method provides a comparative measurement of the resistance of woven textile fabrics to abrasion, and may not necessarily predict the actual performance of fabrics in actual 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.
With permanent abradants that use hardened metal or equivalent surfaces, it is assumed that the abradant will not change appreciably in a specific series of tests, but obviously similar abradants used in different laboratories will not likely change at the same rate due to differences in usage.
Link to Active This link will always route to the current Active version of the standard. If a bias is found, either a cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. As a minimum, test samples that are as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to each laboratory for testing.
Laboratory tests may be reliable as an indication of relative end-use performance in cases where the difference in abrasion resistance of various materials is large, but they should not be relied upon where differences in laboratory test findings are small. ACT reminds you that there are many points to consider when specifying textiles.

If bias is found, either its qstm must be found and corrected, or future test results must be adjusted in consideration of the known bias.
There is no correlation axtm Wyzenbeek and Martindale results. The resistance to abrasion is affected by many factors, such as the inherent mechanical properties of the fibers; the dimensions of the fibers; the structure of the yarns; the construction of the fabrics; and the type, kind, and amount of finishing material added to the fibers, yarns, or fabric.
Combining values from the two systems may result in nonconformance with the specification. In an effort to bring further clarity to the appropriate consideration of double rub numbers, as of April 1,textile companies and furniture manufacturers that use the ACT certification mark for abrasion on their samples will now include the following statement whenever publishing test results in excess of d44157, double rubs:
