The purpose of UV aging testing artificial leather is to evaluate its weather resistance and durability to determine its service life and performance under long-term exposure to solar radiation and other climatic conditions.
Ultraviolet radiation may have the following effects on artificial leather: Fading: Ultraviolet radiation can cause the color of the artificial leather surface to fade or fade; Hardness: Long-term ultraviolet radiation may cause artificial leather materials to harden and lose softness and elasticity; Fracture and cracking: Ultraviolet radiation can cause fracture and cracking of artificial leather materials, reducing their strength and durability; Deformation: Long-term ultraviolet radiation can cause deformation, warping or twisting of artificial leather materials.
Reference standard
The UV aging test of artificial leather can refer to the following 2 industry standards:
ISO 105-B04: This standard specifies one of the test methods for light resistance of textiles and related materials and is suitable for evaluating the weather resistance of artificial leather.
ASTM G155: This standard specifies the UV radiation aging test method for materials under outdoor exposure conditions and can be used to evaluate the weather resistance of artificial leather.
Specific application cases
Automotive interior: Artificial leather is often used in car seats, steering wheel covers and other parts, and UV aging test can evaluate its weather resistance and color stability.
Furniture: Artificial leather is widely used in furniture manufacturing, and UV aging tests can assess changes in durability and surface quality.
Footwear and Leather Goods: Artificial leather is also commonly used in the manufacture of footwear and leather goods, and UV aging tests can assess its durability and appearance quality.
Test procedure
Use the UV aging Test Chamber to test the aging resistance of artificial leather, generally follow the following steps:
Preparation of samples: According to the characteristics and dimensions of the actual artificial leather, prepare samples that meet the requirements, including artificial leather materials and finished products.
Set test conditions: According to the test requirements or applicable standards, set the test conditions such as ultraviolet radiation intensity, temperature and humidity.
Sample placement: Place the artificial leather 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.
Running test: According to the set test conditions, the sample is continuously exposed to ultraviolet radiation and other test conditions for a certain period of time.
Observation and Evaluation: Regularly observe and evaluate changes in samples, including color changes, surface conditions, changes in physical properties, etc., and record and record relevant data.
RESULTS ANALYSIS: The aging resistance and expected life of artificial leather were evaluated 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 artificial leather 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.
