The UV aging test program encompasses various experiments, including light aging tests, thermal aging tests, ozone aging tests, humidity and heat aging tests, gas corrosion aging tests, and salt spray corrosion aging tests. These experiments are instrumental in evaluating the durability and reliability of materials and products, as well as determining their service life.
UV Aging Test Types
- UV aging (UVA) test
- UV aging (UVB) test
- UV aging (UVC) test
Requirements for Fluorescent UV Lamp Aging Tests
- Sample dimensions and quantity
- Lamp type (UVA-340, UVA-351, or UVB-313)
- Wavelength and irradiance (e.g., 0.89 W/m² @ 340 nm or 28 W/m² @ 270–700 nm)
- Exposure cycles
- Black panel temperature
UV Aging Testing: A Universal Standard
UV aging testing is a widely adopted standard that simulates natural sunlight and temperature variations to assess the weather resistance and long-term stability of materials. It is a critical evaluation method extensively used in manufacturing, construction materials, automotive components, and other industries. This testing standard ensures product quality and reliability, with compliance mandated across various sectors.
