GB/T 46441-2025 in English

This standard outlines a methodology for assessing the ozone-induced fading stability of color reflective photographs. It provides a structured approach to conduct tests that evaluate how these materials degrade when exposed to ozone. The procedures described are designed to ensure consistency and reliability in the testing process. The standard specifies the conditions under which the tests should be carried out, including environmental factors and measurement techniques. It also details the equipment required and the steps necessary to obtain accurate results. The framework allows for the comparison of different materials and their resistance to ozone-related fading. The information provided supports the development of reliable testing protocols for the industry.
