ASTM E1647 Ultraviolet Radiation Resistance Testing
The ASTM E1647 standard provides a method to determine the resistance of materials to ultraviolet (UV) radiation. This test is crucial in aerospace and aviation, where exposure to solar UV radiation can significantly affect material durability and performance. The test simulates environmental conditions that aerospace components are likely to encounter during their lifecycle.
The standard specifies a procedure for exposing specimens under controlled conditions with concentrated UV radiation from xenon arc lamps. The testing environment must replicate the high-altitude atmosphere, which is rich in UV light. This exposure can simulate up to 10 years of outdoor aging or more, depending on the specimen's material properties and expected service life.
Compliance with ASTM E1647 ensures that materials used in aerospace components are robust against degradation from UV radiation. This test helps manufacturers ensure their products meet stringent quality standards for durability, reliability, and performance under harsh environmental conditions.
The testing process involves several critical steps: specimen preparation, exposure to UV radiation, and subsequent evaluation of the specimens' physical properties. Specimens must be carefully prepared according to ASTM E1647 guidelines, ensuring they are representative of actual materials used in aerospace applications. The test environment is strictly controlled, with temperature and humidity levels maintained to simulate high-altitude conditions.
After exposure, specimens undergo detailed evaluation using a range of mechanical tests such as tensile strength, flexural modulus, impact resistance, and others. These tests help determine the extent of material degradation due to UV radiation. The results are compared against baseline data to assess the material's UV resistance.
The ASTM E1647 standard is widely recognized in the aerospace industry for its accuracy and reliability. Compliance with this standard ensures that materials used in critical components like aircraft skins, landing gear, and avionics enclosures can withstand prolonged exposure to UV radiation without significant degradation.
By adhering to ASTM E1647, manufacturers can ensure their products meet the stringent quality requirements of aerospace standards such as AS9100. This compliance is essential for maintaining a high level of trust among customers and regulators.

Use Cases and Application Examples
The ASTM E1647 Ultraviolet Radiation Resistance Testing is applicable in various aerospace components where UV exposure is a critical factor. Some key use cases include:
- Aircraft Skin: The outer layer of an aircraft is exposed to direct sunlight, making it susceptible to UV radiation damage.
- Landing Gear: Components that come into contact with the ground during takeoff and landing are subjected to environmental stresses, including UV exposure.
- Airbus A320: This commercial aircraft model is extensively used in various environments globally. Ensuring its materials meet ASTM E1647 standards can enhance its longevity and reliability.
By conducting this test, manufacturers ensure that the materials used in these components are resilient against UV radiation, thereby extending their service life and improving overall performance. This is particularly important for aircraft operating at high altitudes where UV exposure is more intense.
For example, a manufacturer of avionics enclosures may use ASTM E1647 testing to ensure that the materials used in these components can withstand prolonged exposure to UV radiation without significant degradation. This not only enhances the product's durability but also improves its reliability and performance under harsh environmental conditions.
