ASTM D Test Method for Abrasion Resistance of Textile Fabrics
In general, d49666 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.
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.
Weigh one specimen to determine pre-test mass. Avoid getting oil, water, grease, etc.
Abrasion Resistance of Textile Fabrics Using Martindale
Add the required d466 9kpa for apparel, 12kPa for upholstery by resting the weights on the ends of the handles. Take care not to apply too much pressure on the cutting die as it will break the razor blades.
Placing the cut specimen with the technical face down into the gold ring. Starting the abrasion tester 1. 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.
If a bias is found, either its c4966 must be found and corrected or the purchaser and the supplier must agree to interpret future test results in light of the known bias. Fabrics of all types may be tested by this method but difficulties may arise with fabrics with a pile depth greater than 0.
Describe the material or product sampled and the method of sampling used. Screw d496 handle back on. Standard Test Method f The machine should already be programmed to run a batch of movements. With permanent abradants that use hardened metal or equivalent surfaces, it is assumed that the abradant will d9466 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 qstm usage.
ASTM D – Test Method for Abrasion Resistance Martndale | Rycobel
Make all tests in the standard atmosphere for testing. 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.
Loosening and lifting off the black knobs on aastm of the tester. The end point if reached for a woven when two or more yarns have broken, or for a knitted fabric when a hole appears.
There are three options for testing abrasion resistance included in this method. When using this equipment for scientific purposes, the fabric must be prepared according to ASTM D With disposable abradants, the abradant is used only once or changed after limited use.
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.
Report the type of abradant and the mass of the weights used. Note that all three parts of the specimen holders handle, face, and ring are numbered astk correspond to numbers on top of the Martindale tester.
Preparation of Test Apparatus see manual 1.
Historical Version s – view previous versions of standard. Observe s4966 record the results after each batch of movements until you have Reached the desired number of movements total of Using the smallest cutting die, cut six circular specimens from the fabric to be tested with each specimen being 1. 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.
Removing the silver covers held on by the black knobs. While “abrasion resistance” and “durability” frequently are related, the relationship varies f4966 different end uses, and different factors may be necessary in any calculation when trying to predict durability based on findings from specific abrasion tests.
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. Set the counter system to record the desired movements using the third black asstm from the right.
