Other fabrics with established test values may be used for this purpose.
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. 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 ofdouble rubs: 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.
Wyzenbeek testing measures flat abrasion resistance and does not consider edge abrasion or other types of surface wear that may occur in actual upholstered applications.
Association of Contact Textiles Website. Link to Active This link will always route to the current Active version of the standard.
Four options for evaluation are included:. The relationship varies with different end uses, and different factors may aetm necessary in any calculation of predicted durability from specific abrasion data.
Historical Version s – view previous versions of standard. Collectively, these considerations will facilitate your selection of the most appropriate fabric for the project. Historical Version s – view previous versions of standard.
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. For survey details and additional research, read our White Papers. ACT reminds you that there are many points to consider when specifying textiles.
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. If bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability f4157 chosen prior to the testing series.
With disposable abradants, the abradant is used only once or changed after limited use. Because there is a definite need for measuring the relative resistance to abrasion, this is one of the several standardized guides and methods that is useful to help minimize the inherent variation in results that may occur.
Wyzenbeek — New Test Video. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The resistance to abrasion is affected by many factors that include the inherent mechanical properties of the fibers; the dimensions of the fibers; the structure of the yarns; the construction of the fabrics; the type, kind, amount of treatment added to the fibers, yarns or fabric; the nature of the abradant; the tension on the specimen; the pressure between the specimen and the abradant; and the dimensional changes in the specimen.
ASTM D – 08() Standard Guide for Abrasion Resistance of Textile Fabrics (Uniform Abrasion)
This test can also increase the uniformity of the abrading action by washing away abrasion debris and preventing the build up of broken fibers that can interfere with the proper progression of the tests.
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. However, caution is advised because anomalous results may occur due to uncontrolled factors in manufacturing or other processes.
This test method may not be usable for some fabric constructions. All of the following issues should be included in any such assessment: 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. Other procedures for measuring the abrasion resistance of textile fabrics are given in: For more information please refer to abrasion white papers on the ACT website.
Wyzenbeek results abovedouble rubs have not been shown to be an indicator of increased lifespan. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. For example, a predetermined number of abrasion cycles at specified test conditions may be performed on a series of specimens, which are then subjected to a strength or barrier performance test.
The number of cycles that the fabric can endure before fabric shows objectionable change in appearance yarn breaks, pilling, holes is counted. Link to Active This link will always route to the current Active version of the standard. 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.
Combining values from the two systems may result in nonconformance with the specification. My go to reference on the subject is astn Association for Contract Textiles. Four options for evaluation are included: Make sure to check a new post from the Association of Contract Textiles regarding acceptable abrasion standards.
Understanding Abrasion Testing
It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and determine the applicability of regulatory limitations prior to use.
The abradant must accordingly be changed at frequent intervals or checked periodically against a standard. Studies have shown that Wyzenbeek test results on the same fabric can and do vary significantly from test to test.
Within the text, the inch-pound units are shown in parentheses. Fabrics of all types including carpets, garments and nonwovens may be tested under this method. A Wyzenbeek machine is used for this test allowing samples of the test fabric to be f4157 tight in a frame and held stationary. A fabric with twice the number of abrasion cycles does not indicate double the service life. 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 sstm laboratory abrasion tests and actual wear in the intended end-use.
Other procedures for measuring the abrasion resistance of textile fabrics are given in: Whenever possible all materials that are to be compared with each other should be tested under the same pressure and tension. Wire screen or wire mesh is used as an abradant when the test specimen is more abrasive than the cotton duck.
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.
