ASTM-F510:2008 Edition

1.1 This test method covers the laboratory procedure for determining the abrasion resistance of resilient flooring using an abrader with a grit feeder.

1.2 The equipment used in this test method is a modification of the Taber abraser. The regular ceramic wheels are replaced by leather clad brass rollers. A grit-feeding device feeds 240-mesh aluminum oxide grit onto the specimen before it passes under the leather clad rollers. Using the exhaust system incorporated in the apparatus, the used grit and abraded material are continuously removed after passing under both rollers.

1.3 This test method employs a rotary, rubbing action caused by the dual abrading wheels. One wheel rubs the specimen from the center outward and the other from the outside toward the center. The wheels traverse a complete circle and have an abrasive action on the rotating specimen at all angles. It is felt that this action approaches the twisting action between shoe and floor that occurs when a person turns. The use of loose grit serves the function of an abradant and also aids in the rolling action felt to be characteristic of normal walking.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
