The purpose of UV aging testing appliances is to evaluate their weather resistance and durability to determine their service life and performance under long-term exposure to solar radiation and other climatic conditions. Testing can be performed using a UV aging Test Chamber.
Ultraviolet radiation may have the following effects on home appliances:
Fading: UV radiation can cause the color of the home appliance shell or panel surface to fade or fade.
Deformation: Long-term UV radiation may cause deformation of appliance materials, such as deformation, warping or twisting of plastic materials.
Functional loss: UV radiation may cause the functional performance of home appliance components to decrease, such as failure of electronic components, loose interface connections, etc.
Surface quality changes: UV radiation can cause quality changes such as cracks, oxidation or chalking on the surface of the home appliance shell.
Industry standard
The industry standards that meet the ultraviolet aging test of home appliances mainly include the following two:
IEC 60068-2-5: This standard specifies the test methods and procedures for solar radiation aging of household appliances.
ISO 4892-2: This standard specifies the methods and procedures for the UV radiation aging test of plastic materials under laboratory conditions, suitable for the testing of household appliance components.
Specific application cases
TVs: TVs are often exposed to indoor sunlight, and UV aging tests can assess the color stability and surface quality changes of their shell materials.
Refrigerators and washing machines: Refrigerators and washing machine housings are often exposed to humidity and high temperatures, and UV aging tests can assess their weather resistance and appearance quality.
Air conditioning: The outdoor unit of the air conditioner is often exposed to sunlight, and the UV aging test can evaluate the weather resistance and color stability of its shell material.
Test method
Use the UV aging Test Chamber to test the aging resistance of home appliances, generally follow the following steps:
According to the characteristics and size of the actual home appliance, prepare samples that meet the requirements, including shell materials, panels, etc.
According to the test requirements or applicable standards, set the test conditions such as ultraviolet radiation intensity, temperature and humidity.
Place the appliance sample on the sample table in the UV aging Test Chamber to ensure that the sample is exposed to a light source of UV radiation.
According to the set test conditions, the sample is continuously exposed to ultraviolet radiation and other test conditions for a certain period of time.
Regularly observe and evaluate changes in samples, including color changes, surface conditions, functional properties, etc., and record and record relevant data.
Assess the aging resistance and expected life of the appliance based on sample changes and performance losses observed during the test.
NBChao Tip: The specific test steps and parameter settings should be adjusted and confirmed according to the test standards, the characteristics of home appliances and actual needs. It is recommended to refer to the applicable standards and instructions for use of related equipment before performing the UV aging test to ensure the accuracy and reliability of the test.
