International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights.

This International Standard is used in conjunction with other standards which provide specific test methods, description of sample preparation and testing apparatus, evaluation criteria, and test reports. Emphasis is placed on the evaluation methods to ensure a definite set of international standards for reporting the different phenomena observed during and at the completion of testing. This International Standard is intended for use in conjunction with other applicable standards ortest procedures (ASTM,IsO,SAE,JASO,andotherprojectorcompany-specifictestingprograms)tofullyassessafriction material's adequacy for use in a certain application, market or vehicle platform. This International Standard different vehicle conditions of temperature,mechanical stresses, environments,contamination, and operating conditions of the braking system as observed during actual vehicle operation.
