This standard is used and provides a Other standards bodies test methods, the use of sample preparation and testing instruments and evaluation criteria described in the test report and binding. Focused on ensuring A standard evaluation method to test completed during the report observe different phenomena. This standard should cooperate with other applicable standards or test procedures (ISO , SAE, JIS/JASO, national legislation or regulations, or other items with users Test procedure body) used in combination, as under certain conditions, market or car plant to provide a friction material sufficiency complete evaluation. The standard Motion does not include requirements for performance and durability, the appearance of ornaments, or under different temperature conditions, mechanical stress, environmental pollution, in real It observed the occasion of the brake system operating conditions of the vehicle operation. Brake pad and brake shoe is a key component of the vehicle braking system. Corrosion caused by the generation of security issues within the vehicle life cycle Or increase maintenance costs. Since the brake is part of the vehicle chassis, a detailed assessment of corrosion needs a unified and comprehensive laboratory tests Procedures and evaluation criteria. Since the corrosion-related phenomena are complex, this international standard for different existing standards were unified. Previous experience in similar situations is to support the choice of coating systems or specific applications useful way. Brake pad or shoe in a corrosive ring Environments such as durability depends largely on the work environment, system design, paint thickness and composition, surface treatment, application, drying and place Li and other factors. The main concern is the chemical and physical properties of the dry film thickness and bonding agents. Artificial aging test for assessing these characteristics are use. The main tests are. --- Resistant to moisture; --- Resistant to fog; --- Chemical resistance. Artificial aging test results should be analyzed carefully. Exposure to artificial and natural exposure does not necessarily have the same effect. Application process vehicle Not all the factors in the appropriate manner can speed up or slow down aging. Where feasible, it is necessary to plan and carry out long-term nature Exposure or field tests to abnormalities resolved. Since the model-based laboratory corrosion test to predict the life of the industry is not widely accepted. Given the application process or the real environmental assessment Inter durability is beyond the scope of this standard. Road vehicles - Brake lining friction materials Painted brake shoe back and corrosion evaluation methods1 ScopeThis standard specifies the method on the backplane or on a disc brake drum brake shoe testing and evaluation of corrosion resistance. Methods and evaluation criteria of the standard ISO 15484 is mentioned in the product specification/validation phase and a production phase of monitoring section. This standard applies only to the laboratory performance test, whether it is static or cyclic. Does not apply to field test or test site.2 Normative referencesThe following documents for the application of this document is essential.
