During braking, the brake by the driver Clamping force structure generated by the friction material is pressed against the rotating brake drum or brake disc. Such cars with a kinetic energy in the most conversions Heat. For the comfort and braking performance brake system, the disc brake pads and drum brake linings and an important basis for use. Disc brake pad friction material includes friction material itself and carry back, in some cases, as well as reduce noise attachments, grinding Loss alarm device, location or orientation of components. Typically friction material is permanently bonded to the back plate, this should work through a bond Order to achieve, in the process friction material is subjected to the action of heat and pressure. Between the friction material and the back plate can be embedded in the primer, so You can improve the adhesion strength and other characteristics. Drum brake linings is the friction material itself, its shape and then mated to the brake shoe Consistent radius. Usually glued or riveted way friction material and the support of the brake shoes together. Generally, the friction material Fibrous materials, adhesives, anti-adhesive, metal and other filler. Friction material type, metal back, noise devices, fixed and spring Wear warning devices determined by the corresponding drawings. The basic purpose of the development of this standard are. --- To ensure that the product has been verified and approved at all stages of development, so that a smooth transition to full production; --- Improve product reliability while reducing cost of test; --- Establish the necessary and, unanimously approved test criteria include performance and noise, including. The main reason for using the statistical method of evaluation is due to the extension of the production process and compression ratio of the area of \u200b\u200bthe test piece varies. The standard Procedures involved are quasi-ISO /T S16949 basis, covering the entire product quality planning process, start straight from the product definition phase To determine the parameters of formal production. These are standard in this phase 1 to phase 7 made provision. Road vehicles - Brake lining friction materials Product validation and quality assurance1 ScopeThe proposed standard procedures applicable to the motor vehicle disc brake pad and drum brake linings, and the quality assurance systems of these linings Described. Including the tolerance range, including the test methods and test results set forth in this standard allows for disc brake pads make a quick comment. Since the unified product development at all stages of the work program, so that in between customers and suppliers, not only with the quality assurance requirements A clear and consistent understanding of the program and make global applications possible. This standard relates to the entire friction material for friction materials from product development to quality assurance of the production process, as the focus "Element" of the friction material. So the test to avoid the obvious "system" feature is reasonable. Raw material inspection and process control are outside the scope of this standard.2 Normative referencesThe following documents for the application of this document is essential.
