What is the ISO standard for color fastness?

The ISO standard for color fastness is documented in several ISO standards, each focusing on different aspects of color fastness in various materials. The most relevant standards for color fastness are within the ISO 105 series. Here are some key standards within this series:

1. ISO 105-A02:2014 - Textiles — Tests for colour fastness — Part A02: Grey scale for assessing change in colour:

   This standard specifies a grey scale for assessing changes in color of textiles, including those of leather, paper, and other materials.

2. ISO 105-A03:2014 - Textiles — Tests for colour fastness — Part A03: Grey scale for assessing staining:

   Similar to A02, this standard focuses on a grey scale, but specifically for assessing staining in textiles.

3. ISO 105-A05:1996 - Textiles — Tests for colour fastness — Part A05: Instrumental assessment of change in colour for determination of grey scale rating:

   This standard provides methods for the instrumental assessment of changes in color, particularly for determining the grey scale rating.

4. ISO 105-A06:2010 - Textiles — Tests for colour fastness — Part A06: Calculation of colour differences:

   Describes methods for calculating color differences based on instrumental measurements, providing a quantitative assessment of color changes.

5. ISO 105-A08:2018 - Textiles — Tests for colour fastness — Part A08: Determination of the fastness of fluorescent whitening agents to artificial weathering:

   Focuses on the fastness of fluorescent whitening agents when exposed to artificial weathering conditions.

6. ISO 105-C06:2010 - Textiles — Tests for colour fastness — Part C06: Colour fastness to domestic and commercial laundering:

   Specifies methods for assessing the color fastness of textiles to domestic and commercial laundering processes.

7. ISO 105-D01:2010 - Textiles — Tests for colour fastness — Part D01: Colour fastness to dry-cleaning using perchloroethylene solvent:

   Describes procedures for evaluating color fastness to dry-cleaning processes using perchloroethylene solvent.

8. ISO 105-E04:2013 - Textiles — Tests for colour fastness — Part E04: Colour fastness to perspiration:

   Specifies methods for determining the color fastness of textiles to perspiration, simulating the effects of human sweat.

9. ISO 105-J01:2014 - Textiles — Tests for colour fastness — Part J01: General principles of testing:

   Outlines general principles and guidelines for conducting color fastness tests on textiles.

These standards collectively provide a comprehensive framework for evaluating the color fastness of textiles and other materials in various conditions. Each standard within the ISO 105 series focuses on specific aspects of color fastness, ensuring a thorough assessment of the material's color stability under different circumstances.
