Rubber, vulcanized or thermoplastic - Determination of resistance to abrasion - Driven, vertical abrasive disc method WARNING 1 -- Persons using this document shall have practical experience with formal laboratory work. This document does not point out all possible safety issues. It is the user's responsibility to take appropriate safety and health measures and to ensure compliance with the relevant national regulations. WARNING 2 -- Some of the steps specified in this document may involve the use or generation of certain wastes, which may be hazardous to the local environment. Appropriate safe handling and post-use disposal provisions shall be specified in the relevant documentation.1 ScopeThis Standard describes a method for determining the abrasion resistance of rubber with a vertically driven abrasive disc. The wheel-shaped rubber specimen and the grinding disc are perpendicular to each other and are pressed against each other according to the set load. Abrasion mass loss is determined by setting different slip angles, rotational speeds and certain loads between the wheel-shaped specimen and the grinding disc for slippage. Test results are expressed in terms of mass loss per unit run distance and/or abrasion resistance index compared to a reference compound. This document applies to comparative testing, quality control, normative compliance testing, arbitration testing, and R&D work. Since the test device can independently set various wear parameters, such as: slip angle, grinding disc rotation speed and load, this method can be widely used in the wear test of various rubber products (especially tires).2 Normative referencesThe following referenced documents are indispensable for the application of this document.
