The ASTM F 2357-10 standard describes a method for abrasion resistance testing of coatings and inks on panel keys using a Normantool RCA paper tape Abrasion machine. The main purpose of this test method is to evaluate the abrasion damage that membrane switch keys may suffer during daily use, such as the impact of factors such as cleaning, friction on coatings and inks. The test is applied to a variety of materials and provides a way to compare the relative abrasion resistance of different materials, but does not provide a specific number of human finger touches. The standard can be used for quality control, research and development, and material performance comparisons to ensure that the product maintains its Appearance and performance during use.
