Terminology2.1 Definitions:2.1.1 final breakthrough, nthe number of cycles until complete removal of the first surface ink or coating being tested.2.1.2 membrane switch, na momentary switching device in which at least o

6、ne contact is on, or made of, a flexible substrate.2.1.3 wear limit, nin testing membrane switches, the number of cycles until an underlying layer of different color may be seenthrough the first layer (not applicable for transparent coatings).3. Significance and Use3.1 Membrane switch keys are subje

7、cted to repeated actuations, usually by a human finger. This can transfer body oil, handcreams, automotive fluids and so forth. Materials are often subjected to other conditions (for example, wiping, cleaning, rubbing)during handling, end-use, shipment, or storage that may cause abrasion damage. The

8、 result may be a significant removal of thecoatings, text, or decorative inks.3.2 This test method is applicable to a wide range of materials. The main criterion is that the abrasion process produces visiblewear or breakthrough of the surface being tested.3.3 The amount of abrasion damage to a surfa

9、ce is dependent on numerous variables. This test method provides a way ofcomparing relative abrasion resistance and the effect of chemicals on inks, coatings, and substrates. In no way do the resultsprovide a correlation value of the number of human finger touches before coating failure. It only pro

10、vides a means to compareresults of tests performed using the same equipment, abrasive materials and loading conditions.3.4 The test method can be used for quality control purposes, as a research and development tool, to evaluate materialcombinations for a given application, or for the comparison of

11、materials with relatively similar properties and the effect ofchemicals on the abrasion resistance.4. Interferences4.1 Inconsistent wear can occur which will compromise the results. Caution is necessary to ensure the mounting method doesnot deflect the specimen, which may influence the wear characte

United States14.2 Contoured surfaces can be tested but results may be more difficult to duplicate and some equipment is not designed to testnon-flat surfaces.4.3 Whenever possible, a smooth surface is preferred. Extra care should be taken when evaluating a non-uniform surface (thatis, roug
