The purpose of UV aging testing of faux leather is to evaluate its weather resistance and durability to determine its service life and performance performance under long-term exposure to solar radiation and other climatic conditions.

Uv irradiation may have the following effects on faux leather: Discoloration: UV radiation will cause faux leather surface color to fade or fade; Hardening: long-term UV radiation may cause faux leather materials to harden and lose softness and elasticity; Fracture and cracking: UV radiation can cause fracture and cracking of faux leather materials, reducing their strength and durability; Deformation: Long-term UV radiation can cause deformation, warping or distortion of faux leather materials.

Standard of reference
The UV aging test of artificial leather can refer to the following two industry standards:

ISO 105-B04: This standard specifies one of the test methods for the lightfastness of textiles and related materials and is suitable for assessing the weatherability of artificial leather.

ASTM G155: This standard specifies the method of ultraviolet radiation aging test for materials under outdoor exposure conditions, which can be used to evaluate the weather resistance of artificial leather.

Specific application cases
Automotive interior: Faux leather is often used in car seats, steering wheel covers and other parts, UV aging test can evaluate its weather resistance and color stability.

Furniture: Faux leather is widely used in furniture manufacturing, and UV aging tests can evaluate its durability and surface quality changes.

Footwear and leather goods: Faux leather is also commonly used in footwear and leather goods manufacturing, where UV aging tests can evaluate its durability and appearance quality.

Procedure of test
Using UV aging test chamber to test the aging resistance of artificial leather, generally can be carried out according to the following steps:

Prepare samples: according to the characteristics and dimensions of actual faux leather, prepare samples that meet the requirements, including faux leather materials and finished products.

Set test conditions: according to the test requirements or applicable standards, set the UV radiation intensity, temperature, humidity and other test conditions.

Sample placement: Place the faux leather sample on the sample table in the UV aging test chamber to ensure that the sample is exposed to the light source of UV radiation.

Run test: Allow the sample to be continuously exposed to UV radiation and other test conditions for a certain period of time according to the set test conditions.

Observation and evaluation: Regularly observe and evaluate the changes of samples, including color changes, surface conditions, physical properties changes, etc., and record and record relevant data.

Analysis of results: The aging resistance and expected life of faux leather were evaluated based on the sample changes and performance losses observed during the test.

tips: specific test steps and parameter Settings should be adjusted and confirmed according to test standards, characteristics of faux leather and actual needs. It is recommended to refer to applicable standards and relevant equipment instructions before performing UV aging tests to ensure the accuracy and reliability of the tests.
