EN 2591 403 Salt Mist Simulation for Aerospace Components
The EN 2591:2021 standard, specifically clause 403, provides detailed procedures and specifications for conducting salt mist tests on aerospace components. This test evaluates the resistance of materials and assemblies to corrosive environments, ensuring their durability in harsh conditions encountered during use.
These tests are crucial due to the exposure of aerospace components to various environmental factors that can lead to corrosion. Salt mist testing simulates the corrosive effects of salt-laden atmospheres, which are common near coastal areas or industrial sites. By subjecting materials and assemblies to these controlled conditions, manufacturers can identify potential weaknesses in their designs early in the development process.
The test procedure involves exposing samples to a fine mist composed primarily of sodium chloride (NaCl) dissolved in water under specific conditions. The duration and severity of exposure depend on the intended use of the component. For instance, components used in aircraft landing gear might require more aggressive testing compared to those in less exposed areas.
Preparation of specimens is critical for accurate test results. Samples must be cleaned thoroughly to remove any contaminants that could interfere with the test outcome. They are then positioned in the test chamber according to predefined standards to ensure uniform exposure across all samples.
The testing apparatus used typically includes a salt mist generator capable of producing a fine mist and a chamber large enough to accommodate the specimens being tested. The temperature, humidity, and salt concentration levels within the chamber must be controlled precisely to meet the specified parameters outlined in EN 2591:2021.
After exposure, specimens are visually inspected for signs of corrosion such as pitting, rusting, or other degradation phenomena. Non-destructive testing techniques may also be employed to assess internal structural integrity. Acceptance criteria vary based on the type and function of the component but generally involve no visible damage within specified limits.
