Introduction

Wear a wide variety of different test trucks and trailers used by the manufacturer is very time consuming, and can lead to the same conditions of use Same pad materials have different evaluation results. Given this situation different test procedures, test results can not correspond to each other. General wear test is very time-consuming and expensive. This standard is committed to reflect the wide range of friction material applications. Make There is a different energy and temperature levels of brake lining wear contain procedures for the friction and wear properties of the material provides a good full Side show. The standards will be different test methods are summarized as a test method, this method with the shortest test cycle to complete all the important wear Property requirements. Coordination of commercial vehicles in the application process, standardized performance tests of friction materials is a top priority. Test and evaluate various conditions friction material should ensure a wide range of data. These data are very important at different stages of the product Such as product development and production processes, product validation, quality control, product specifications and practical application of assessment. This standard should be combined with other standards or test procedures (ISO , SAE, JIS/JASO, national laws or regulations, and other items or users Specified test procedure) in order to fully evaluate the use of specific conditions of use, adequacy or vehicle platform under the market conditions of the friction material. This standard It does not include braking distance under national regulations or laws different speed, temperature, tire adhesion, load conditions and braking control system explained Or braking force distribution-related performance requirements. This standard is part of the friction material globally standardized ISO 15484, is the major car manufacturers, brake systems and parts manufacturing Manufacturers, product testing services and standards organizations such as the close cooperation between SAE and JIS/JASO of.
