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

A fabric with twice the number of abrasion cycles does not indicate double the service life. 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.

In fact, Wyzenbeek results abovedouble rubs have not been shown to be an indicator of increased fabric lifespan.

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.

Combining values from the two systems may result in nonconformance with the specification. Martindale Test Video —. The relationship varies with different end uses, and different factors may be necessary in any calculation of predicted durability from specific abrasion data.

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. Wyzenbeek — New Test Video View: 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. ACT reminds you that there are many points to consider when specifying textiles. Collectively, these considerations will facilitate your selection of the most appropriate fabric for the project.

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. Other procedures for measuring the abrasion resistance of textile fabrics are given in: As a minimum, the test samples should be used that are as homogenous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing.

A Wyzenbeek machine is used for this test allowing samples of the test fabric to be pulled tight in a frame and held stationary. 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.

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.

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. 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.

Wyzenbeek results abovedouble rubs have not been shown to be an indicator of increased lifespan.

Understanding Abrasion Testing

This explains the requirements for both residential and contract spaces. ACT studies indicate that results of multiple abrasion tests performed on some woven 4d157 structures may vary significantly — as much as 60 percent or more. 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.

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. The abradant must accordingly be changed at frequent intervals or checked periodically against a standard.

Accordingly, specifiers should consider the following qualifiers when assessing double rub ratings: Within the text, the inch-pound units are shown in parentheses. With disposable abradants, the abradant is used only once or changed after limited 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.

Historical Version s – view previous versions of standard. Specific instances have been described. Association of Contact Textiles Website. 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: Wire screen or wire mesh is used as an abradant when the test specimen is more abrasive than the cotton duck.

Four options for evaluation are included:. 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. Link to Active This link will always route to the current Satm version of the standard. All of the following issues should ast included in any such assessment: The number of cycles that the fabric can endure before fabric shows objectionable change in appearance yarn breaks, pilling, holes is counted.

This test method may not be usable for some fabric constructions.
