Preparation of Test Apparatus see manual 1. Set the counter system to record the desired movements using the third black button from the right.

ASTM D4966

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Observe and record the results after each batch of movements until you have Reached the desired number of movements total of Place the assembled holders into the machine, replacing silver caps and black knobs.

The between-laboratory precision of this test method is poor and, because of the nature of abrasion testing itself, technicians frequently fail to obtain results in agreement on the same type of testing instrument, both within and between laboratories. The measurement of the relative amount of abrasion also may be affected by the method of evaluation and may be influenced by the judgment of the operator. Resistance to abrasion is evaluated by various means, including comparison to visual aids in the form of photographs or actual samples.

Add the required weight 9kpa for apparel, 12kPa for upholstery by resting the weights on the ends of the handles. Abrasion resistance is measured by subjecting the specimen to rubbing motion in the form of a geometric figure.

Standard Test Method f Using the smallest cutting die, cut six circular specimens from the fabric to be tested with each specimen being 1. Removing the silver covers held on by the black knobs.

Link to Active This link will always route to the current Active version of the standard. This test method covers the determination of the abrasion resistance of textile fabrics. The face must sit flush and square inside the ring. Permanent abradants also may change due to pick up of finishing or other material from test fabrics and must accordingly be cleaned at frequent intervals.


Agreement between laboratories conducting this test is poor, but it is used widely, especially outside the United States.

Take care not to apply too much pressure on the cutting die as it will break the razor blades. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. There are three options for testing abrasion resistance included in this method.

Describe the material or product sampled and the method of sampling used. Report the type of abradant and the mass of the weights used. Historical Version s – view previous versions of standard. The test specimens then should be assigned randomly in equal numbers to each laboratory for testing. The resistance of textile materials to abrasion as measured on a testing machine in the laboratory is generally only one of several factors contributing to wear performance or durability as experienced in the actual use of the material.

Fabrics of all types may be tested by this method, including woven, non-woven, and knit apparel fabrics, household fabrics, industrial fabrics, and floor coverings, but difficulties may arise with fabrics with a pile depth greater than 2mm.

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. State that the specimens were tested as directed in Test Method D The average results from the two laboratories should be compared using Students t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun.


Make all tests in the standard atmosphere for testing. The end point is reached for a woven fabric atsm two or more yarns have broken, or for a knitted fabric when a hole appears. It is the responsibility of the user of this standard to d44966 appropriate safety and health practices and determine the applicability of xstm limitations prior to use.

The machine should already be programmed to run a batch of movements. For the purposes of the Quality Assurance Class, you will be using Option 1. Screw the handle back on.

Note that all three parts of the specimen holders handle, face, and ring are numbered and correspond to numbers on top of the Martindale tester. While aatm resistance” and “durability” frequently are related, the relationship varies with different end uses, and different factors may be necessary in any calculation when trying to predict durability based on findings from specific abrasion tests.

Avoid getting oil, water, zstm, etc. The abradant must be changed accordingly at frequent intervals or checked periodically against a standard. With permanent abradants that use hardened metal or equivalent surfaces, it is assumed r4966 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.

When cutting specimens, avoid wrinkles, folds or creases. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Turn the power on. Put specimens back on the machine and continue with the test.

Assemble the holder by: Remove the specimen holders from the Martindale tester by a. Loosening and lifting off the black knobs on top of the tester. Fabrics of all types may be tested by this method but difficulties may arise with fabrics with a pile depth greater than 0.
