State that the specimens were tested as directed in Test Method D While “abrasion resistance” e4966 “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. Placing the cut specimen with the technical face down into the gold ring.

This test method covers the determination of the abrasion resistance of textile fabrics. Assemble the holder by: When using this equipment for scientific purposes, the fabric must be prepared according to ASTM D Put specimens back on the machine and continue with the test. Agreement between laboratories conducting this test is poor, but it is used widely, especially outside the United States.

ASTM D4966

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. Although this test method is not recommended for acceptance testing, it is useful because it is used widely, especially outside the United States.

Weigh one specimen to determine pre-test mass. The machine should already be programmed to run a batch of movements. Make all tests in the standard atmosphere for testing.

Report the type of abradant and the mass of the weights used. When cutting specimens, avoid wrinkles, folds or creases.

Observe and record the aastm after each batch of movements until you have Reached the desired number of movements total asgm 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. Describe the material or product sampled and the method of sampling used. There are xstm options for testing abrasion resistance included in this method. Remove the specimen holders from the Martindale tester by a.

After the first batch is complete take specimen holders off of the machine and observe And record the results and changes in specimens. Abrasion resistance is measured by subjecting the specimen to rubbing motion in the form of a geometric figure.

Screw the handle back on. 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.

ASTM D Test Method for Abrasion Resistance of Textile Fabrics

Using the smallest cutting die, cut six circular specimens from the fabric to be tested with each specimen being 1. How the Test Works: The face must sit flush and square inside the ring. For the purposes of the Quality Assurance Class, you will be using Option 1. 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.

Removing the silver covers held on by the black knobs. Fabrics of all types may be tested by this method but difficulties may arise with fabrics with a pile depth greater than 0. Push the green button to start the batch 3. Loosening and lifting off the black knobs on top of the tester.

Link to Active This link will always route to the current Active version of the standard. Add the required weight 9kpa for apparel, 12kPa for upholstery by resting the weights on the ends of the handles.
