The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Observe and record aastm results after each batch of movements until you have Reached the desired number of movements total of State the average number of movements required asmt rupture two or more yarns in a woven fabric or develop a hole in a knitted fabric.

Lifting the specimen holders out 3. Starting the abrasion tester 1.

Ast the power on. The end point if reached for a woven when two or more yarns have broken, or for a knitted fabric when a hole appears. Avoid getting oil, water, grease, etc.

Abrasion Resistance of Textile Fabrics Using Martindale

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 light of the known bias. The test specimens then should be assigned randomly in equal numbers to each laboratory for testing. When using this equipment for scientific purposes, the fabric must be prepared according to ASTM 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.

Historical Version s – view previous versions of standard. Put specimens back on the machine and continue with the test. 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.


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.

ASTM D – Test Method for Abrasion Resistance Martndale | Rycobel

While “abrasion 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. Link to Active This link will always route to the current Active version of the standard.

The machine should already be programmed to run a batch of movements. Loosening and lifting off the black knobs on top of the tester. Using the smallest cutting die, cut six circular specimens from the fabric to be tested with each specimen being 1.

ASTM D4966

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. How the Test Works: The abradant must be changed accordingly at frequent intervals or checked periodically against a standard. Describe the material or product sampled and the method of sampling used. Make all tests in the standard atmosphere for testing.

Push the green button to start the batch 3. Fabrics of all types may be tested by this method but difficulties may arise with fabrics with a pile depth greater than 0. Assemble the holder by: With disposable abradants, the abradant is used only once or changed after limited use. 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.


Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Remove the specimen holders from the Martindale tester by a. When cutting specimens, avoid wrinkles, folds or creases.

Weigh one specimen to determine pre-test mass. Removing the silver covers held on by the black knobs. Competent statistical assistance is recommended for the investigation of bias. Abrasion resistance is measured by subjecting the specimen to rubbing motion in the form of a geometric figure. Place the assembled holders into the machine, replacing silver caps and black knobs.

This test method covers the determination of the abrasion resistance of textile fabrics. 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.

Although this test method is not recommended for acceptance testing, it is useful because it is used widely, especially outside the United States. Add the required weight 9kpa for apparel, 12kPa for upholstery by resting the weights on the ends of the handles. The end point is reached for a woven fabric when 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
