ISO/DIS 18511-2

Scope of the proposed deliverable. This international standard (part 1 or part 2) specifies the method for measuring tread abrasion mass loss of a candidate tyre per unit distance travelled, under loaded conditions, by using vehicles on road (part 1) or an external drum tester (part 2). Each test method specified in Part 1 and Part 2 measures abrasion performance of a candidate tyre on the running mode representing vehicle driving conditions of the world. The test method specified by Part 1 and Part 2 uses reference tyres. The target is to define methods with the following characteristics: - repeatable, - reproducible, - practicable, - representative of worldwide driving environment, - usable for regulation purpose (including market surveillance), - cost efficient, - aiming for having a correlation between the 2 test methods in line with driving conditions of the world,
