Friction linings are composite materials with complex structure. Due to their composition and their productionprocess, visual appearance characteristics can occur which in a precisely defined design are to be regardedas specific to the product. This International Standard defines visual aspect for the identification andassessment of such product characteristics in quality assurance, as well as a basis for commercial andtechnical agreements. The sequence of the product characteristics represents no order of priority. The brakelinings are inspected in the “as supplied” condition, meaning unused. In some characteristic features, thereare differences between brake linings with an effective lining pad surface < 120 cm2 and W 120 cm2. Theacceptance criteria within the International Standard do not allow any characteristics which could impair thefunction and performance of brake linings and are applied unless there are other agreements between thecustomer and the supplier.
