Can you provide some new test methods for color fastness that are standardized and normalized?

Standardization and normalization are very important when it comes to color fastness test methods as they ensure repeatable and comparable test results. Below are some examples of new test methods that have been standardized and normalized:

1. ASTM D7860-13: This is a standardized method for assessing the color stability of dyes through the use of optical imaging. The test method uses a digital camera to photograph the material and computer software to analyze the image data to assess color change.

2. ISO 105-J03: This is an international standard for assessing the color stability of dyes through the use of spectroscopic techniques. The test method uses a photometer and colorimeter to measure the material and computer software to analyze the spectral data to assess color change.

3. GB/T 11047-2018: this is a Chinese national standard for assessing the color stability of dyes through the use of artificial intelligence techniques. The test method uses machine learning algorithms to analyze and model test data and predict the color fastness of materials in different environments.

4. DIN EN ISO 105-X12: This is a European standard for assessing the color stability of dyes through the use of microfluidics. The test method uses microfluidic chips to simulate chemical reactions in different environments and computer software to analyze the reaction products to assess color change.

Each of these standardized and regulated color fastness test methods has its own unique advantages and application scenarios, which can be selected and applied according to specific testing needs. When selecting a test method, it is necessary to consider its scope of application, test accuracy, test time, cost and other factors, and to ensure that the test process complies with the appropriate standards and specifications.
