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; Deformasi: 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.

Prosedur tes
Using UV aging test chamber to test the aging resistance of artificial leather, umumnya dapat dilakukan sesuai dengan langkah-langkah berikut:

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.

Tetapkan kondisi pengujian: sesuai dengan persyaratan pengujian atau standar yang berlaku, mengatur intensitas radiasi UV, suhu, kelembaban dan kondisi pengujian lainnya.

Penempatan sampel: 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.

Jalankan tes: Biarkan sampel terkena radiasi UV dan kondisi pengujian lainnya secara terus menerus selama jangka waktu tertentu sesuai dengan kondisi pengujian yang ditetapkan.

Observasi dan evaluasi: Amati dan evaluasi perubahan sampel secara teratur, termasuk perubahan warna, kondisi permukaan, physical properties changes, dll., dan mencatat serta mencatat data yang relevan.

Analisis hasil: 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.
