DIN Abrasion Tester GT-7012-D3

It is applicable to testing the abrasion resistance of polymeric soling materials, finished soles and any polymer based sheet material. A circular specimen is placed in contact, under a specified force, with a rotating cylinder covered with an abrasive paper of given grade. The specimen is then moved along the length of the cylinder so that it travels a helical contact path the abrasive paper. The mass loss of the specimen and its density are measured, and then its volume loss is calculated.
