The SAE ARP 1536 standard, developed by the Society of Automotive Engineers (SAE), includes criteria for the comparative evaluation of wear resistance of friction protection and provides a test method. It also describes the standard test equipment to be used in conducting these tests.
This standard establishes a standard test criterion for the evaluation of wear protections aimed at protecting against wear and friction of cable assemblies and adjacent components. A stainless steel wire braided hose assembly conforming to the MIL-H-25579 standard is used during the tests (MIL-H-25579 Hose assembly, polytetrafluoroethylene, high temperature, medium pressure, general specification standard). The information obtained from the test is applicable to any hose assembly because the test ends when the wear protection test assembly is worn.
Friction protection occurs when a smooth surface is worn or the surface coating of a product is damaged. To prevent rubbing, rubbing guards are designed to help protect hoses from any damage. The friction protection is generally made of synthetic material and steel. Synthetic materials are resistant to damage. Steel is also moisture and water resistant, providing effective long-term safety.
In areas of high vibration or repetitive movements on airplanes, such as the landing gear area, the harnesses are constantly in contact with abrasive surfaces, which can damage the wires. With repeated use, the insulation in the cables wears down over time, causing cable failure. Friction protection is often used to protect these bundles. When choosing anti-friction materials, it is important to choose those that are rated for environmental conditions.
Essentially, the purpose of all safety standards is to identify risks and hazards before they occur, and to ensure that design measures are taken to prevent them or reduce their effects to an acceptable level. The increase in critical safety functions in new generation aircraft necessitated these functions to be performed by complex systems. With the increasing complexity in technology, it is also important to evaluate the acceptability of the design.started the month.
