Introduction

Test procedures unified commercial performance testing of friction material worldwide technology organization is a big challenge. Friction material was tested and evaluated under different conditions in order to determine the breadth of the data. In the different stages of the product life data (Such as manufacturing process development, production validation, quality control, product specifications/problem identification and assessment of applications, etc.) is critical. This standard is part of the friction material globally standardized ISO 15484, is the major car manufacturers, brake systems and parts manufacturing Suppliers, testing services and standardization organizations [such as SAE and JSAE (Japan Automobile Standards Organization)] the product of close collaboration between. By a different truck, trailer manufacturers require a wide range of performance tests have been shown to not only time consuming, but also led to friction same purpose Repeat evaluation material, and due to different test procedures and test conditions, the test results may not coincide with each other.

1 Scope

This standard applies to UNECER.E.3 in M2, M3, N2, N3, O3 and O4 class air brakes for commercial vehicles. This standard also applies to ISO 15484 definition of product development, product trial, product specification or validation and mass-produced products. When used in conjunction with other applicable standards or test procedures, the standard provides a friction material under certain conditions market or car factory Full and complete evaluation methods. Note. Other applicable standards and test procedures including ISO , JIS/JASO (Japanese Industrial Standards/Japan Automobile Standards Organization), SAE (USA Automotive Engineering Institute of Surveyors), national standards or specifications, test procedures, or other items specified by the user. This standard does not include the vehicle under different conditions and the braking distance and the braking force distribution-related performance standards or national regulations to Requirements, different vehicle conditions are mainly speed, temperature, adhesion coefficient, load and brake condition. This standard specifies a single head dynamometer performance test procedures, aimed at the commercial vehicle air brake test procedure standardized for the different All test procedures contain a unique performance requirements. Performance evaluation test sequence includes the following conditions. --- Run-around performance test; --- After running and moderate temperatures after brake failure; --- Temperature, velocity and pressure sensitivity under the influence; --- Downhill simulation; --- Brake recovery.
