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; 変形: Long-term UV radiation can cause deformation, warping or distortion of faux leather materials.

参照基準
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.

Procedure of test
Using UV aging test chamber to test the aging resistance of artificial leather, 一般に、次の手順に従って実行できます。:

Prepare samples: according to the characteristics and dimensions of actual faux leather, 要件を満たすサンプルを準備する, including faux leather materials and finished products.

試験条件の設定: according to the test requirements or applicable standards, set the UV radiation intensity, 温度, humidity and other test conditions.

サンプルの配置: 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, 色の変化も含めて, surface conditions, 物理的特性の変化, 等, 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. テストの精度と信頼性を確保するために、UV 老化テストを実行する前に、該当する規格と関連する機器の説明書を参照することをお勧めします。.
