“ISO 105 vs AATCC 61: Unveiling the Variations in Global Color Fastness Testing Protocols”
Introduction
ISO 105 and AATCC 61 are two different standards used to assess the color fastness to washing of textiles. ISO 105 is an international standard developed by the International Organization for Standardization, while AATCC 61 is a standard developed by the American Association of Textile Chemists and Colorists. The main differences between the two standards lie in the test methods, conditions, and equipment used. ISO 105 uses a variety of test methods depending on the type of textile and washing conditions, while AATCC 61 primarily uses a single test method with different options for different fibers and washing conditions. Additionally, the equipment specified in each standard may differ, with ISO 105 requiring specific types of washing machines and AATCC 61 specifying the use of a Launder-Ometer. These differences can result in variations in test results, making it important for manufacturers and testing laboratories to choose the appropriate standard for their specific needs.
Overview of ISO 105 and AATCC 61 Standards
When it comes to evaluating the color fastness of textiles to washing, two of the most widely recognized standards are ISO 105 and AATCC 61. Both of these standards are used to determine how well a fabric retains its color when subjected to washing conditions. However, there are some key differences between the two that are important to understand.
ISO 105, also known as the International Organization for Standardization, is a global standard that is used to assess the color fastness of textiles. This standard is divided into several parts, each of which focuses on a different aspect of color fastness. For example, ISO 105-C06 is specifically designed to test the color fastness of textiles to domestic and commercial laundering.
On the other hand, AATCC 61, which stands for the American Association of Textile Chemists and Colorists, is a standard that is primarily used in the United States. This standard is also used to evaluate the color fastness of textiles to washing, but it has some differences in the testing procedures and conditions compared to ISO 105.
One of the main differences between ISO 105 and AATCC 61 is the way in which the tests are conducted. ISO 105 uses a standardized washing machine and detergent, while AATCC 61 uses a specialized machine called a Launder-Ometer. The Launder-Ometer is designed to simulate the conditions of a home washing machine, but it uses a smaller volume of water and a different type of detergent.
Another difference between the two standards is the way in which the results are reported. ISO 105 uses a grading system that ranges from 1 to 5, with 1 being the lowest level of color fastness and 5 being the highest. AATCC 61, on the other hand, uses a different grading system that ranges from 1 to 5, with 1 being the highest level of color fastness and 5 being the lowest.
In addition to these differences, there are also variations in the test conditions used by each standard. For example, ISO 105 specifies a range of temperatures and washing times that must be used during the test, while AATCC 61 allows for more flexibility in these conditions. This means that the results obtained from each standard may not be directly comparable.
Despite these differences, both ISO 105 and AATCC 61 are widely recognized and accepted standards for evaluating the color fastness of textiles to washing. Manufacturers and retailers often use these standards to ensure that their products meet the necessary quality requirements. Consumers can also use these standards to make informed decisions about the durability and longevity of their textile purchases.
In conclusion, while ISO 105 and AATCC 61 are both used to evaluate the color fastness of textiles to washing, there are some key differences between the two standards. These differences include the testing procedures, reporting systems, and test conditions used by each standard. Understanding these differences is important for manufacturers, retailers, and consumers alike, as it can help ensure that textiles meet the necessary quality standards and perform as expected.
Industry Applications and Preference for Each Standard
When it comes to testing the color fastness of textiles to washing, two of the most widely recognized standards are ISO 105 and AATCC 61. Both of these standards are used to determine how well a fabric’s color will hold up when subjected to washing, but there are some key differences between the two that are important to understand.
ISO 105, also known as the International Organization for Standardization, is a global standard that is used to test the color fastness of textiles to washing. This standard is widely recognized and used by manufacturers and retailers around the world. It is known for its rigorous testing methods and is considered to be one of the most reliable standards for determining color fastness.
On the other hand, AATCC 61, also known as the American Association of Textile Chemists and Colorists, is a standard that is primarily used in the United States. It is similar to ISO 105 in that it tests the color fastness of textiles to washing, but there are some differences in the testing methods and procedures. AATCC 61 is known for its focus on the American market and is often used by manufacturers and retailers who are looking to sell their products in the United States.
One of the main differences between ISO 105 and AATCC 61 is the way in which the tests are conducted. ISO 105 uses a standardized method that is recognized globally, while AATCC 61 uses a method that is specific to the American market. This means that the results of the two tests may not be directly comparable, as the testing methods and procedures are different.
Another difference between the two standards is the way in which the results are reported. ISO 105 uses a grading system that ranges from 1 to 5, with 5 being the highest level of color fastness. AATCC 61, on the other hand, uses a grading system that ranges from 1 to 8, with 8 being the highest level of color fastness. This means that the results of the two tests may not be directly comparable, as the grading systems are different.
Despite these differences, both ISO 105 and AATCC 61 are widely recognized and used by manufacturers and retailers around the world. Each standard has its own strengths and weaknesses, and the choice of which standard to use often comes down to the specific needs and preferences of the manufacturer or retailer.
For example, manufacturers and retailers who are looking to sell their products globally may prefer to use ISO 105, as it is a globally recognized standard. On the other hand, manufacturers and retailers who are looking to sell their products in the United States may prefer to use AATCC 61, as it is specific to the American market.
In conclusion, ISO 105 and AATCC 61 are two of the most widely recognized standards for testing the color fastness of textiles to washing. While there are some key differences between the two, both standards are widely used by manufacturers and retailers around the world. The choice of which standard to use often comes down to the specific needs and preferences of the manufacturer or retailer, and both standards are considered to be reliable and effective methods for determining color fastness.
Sample Preparation and Mounting Differences
When it comes to evaluating the color fastness of textiles to washing, two of the most widely recognized standards are ISO 105 and AATCC 61. Both of these standards are used to determine how well a fabric can retain its color when subjected to washing, but there are some key differences between the two that are important to understand.
One of the main differences between ISO 105 and AATCC 61 is the way in which samples are prepared and mounted for testing. ISO 105, which is an international standard, requires that the test specimen be cut to a specific size and shape, and then mounted onto a stainless steel frame. This frame is then placed into a washing machine along with a specified number of steel balls, which help to simulate the mechanical action of washing. The washing machine is then set to run for a specific amount of time, at a specific temperature, and with a specific detergent.
On the other hand, AATCC 61, which is an American standard, requires that the test specimen be cut to a different size and shape than ISO 105. The specimen is then mounted onto a plastic frame, which is placed into a washing machine along with a specified number of stainless steel balls. The washing machine is then set to run for a different amount of time, at a different temperature, and with a different detergent than ISO 105.
Another difference between the two standards is the way in which the color change of the test specimen is evaluated. ISO 105 uses a grey scale to evaluate the color change, while AATCC 61 uses a color change scale. The grey scale used in ISO 105 consists of five pairs of non-glossy grey chips, which are used to assess the amount of color change that has occurred. The color change scale used in AATCC 61 consists of nine pairs of colored chips, which are used to assess the amount of color change that has occurred.
In addition to the differences in sample preparation and mounting, there are also differences in the way in which the test results are reported. ISO 105 requires that the test results be reported as a numerical value, while AATCC 61 requires that the test results be reported as a letter grade. The numerical value used in ISO 105 is based on the grey scale, while the letter grade used in AATCC 61 is based on the color change scale.
Overall, while both ISO 105 and AATCC 61 are used to evaluate the color fastness of textiles to washing, there are some key differences between the two standards that are important to understand. These differences include the way in which samples are prepared and mounted, the way in which the color change is evaluated, and the way in which the test results are reported. Understanding these differences is essential for anyone involved in the textile industry, as it can help to ensure that the correct standard is used for the specific application.
Temperature and Time Variations in ISO 105 and AATCC 61
When it comes to evaluating the color fastness of textiles to washing, two of the most widely recognized standards are ISO 105 and AATCC 61. Both of these standards are used to determine how well a fabric retains its color when subjected to washing conditions. However, there are some key differences between the two that are important to understand.
One of the main differences between ISO 105 and AATCC 61 is the temperature and time variations used in the testing process. ISO 105, which is an international standard, specifies a range of different washing temperatures and times that can be used depending on the type of fabric being tested. For example, the standard includes a test for color fastness at 40 degrees Celsius for 30 minutes, as well as a test at 60 degrees Celsius for 30 minutes. This allows for a more comprehensive evaluation of how a fabric will perform under different washing conditions.
On the other hand, AATCC 61, which is a standard used primarily in the United States, specifies a single washing temperature and time for all fabrics. The standard calls for a washing temperature of 49 degrees Celsius for 45 minutes. This means that all fabrics are tested under the same conditions, regardless of their specific characteristics or intended use.
Another difference between the two standards is the way in which the washing is carried out. ISO 105 specifies that the washing should be done in a machine that simulates the action of a domestic washing machine. This includes a specific agitation rate and water level. AATCC 61, on the other hand, specifies that the washing should be done in a machine that uses a specific type of agitation, known as a Launder-Ometer. This machine uses a different agitation rate and water level than a domestic washing machine, which can affect the results of the test.
The differences in temperature and time variations between ISO 105 and AATCC 61 can have a significant impact on the results of the color fastness test. For example, a fabric that performs well under the conditions specified by ISO 105 may not perform as well under the conditions specified by AATCC 61, and vice versa. This is why it is important for manufacturers and testing laboratories to be aware of the differences between the two standards and to choose the one that is most appropriate for the specific type of fabric being tested.
In conclusion, while both ISO 105 and AATCC 61 are used to evaluate the color fastness of textiles to washing, there are some key differences between the two standards in terms of temperature and time variations. ISO 105 allows for a range of different washing conditions, while AATCC 61 specifies a single set of conditions. Additionally, the two standards use different methods for carrying out the washing process. These differences can have a significant impact on the results of the test, making it important for manufacturers and testing laboratories to choose the standard that is most appropriate for their needs.

Interpretation of Results: ISO 105 vs. AATCC 61
When it comes to evaluating the color fastness of textiles to washing, two of the most commonly used standards are ISO 105 and AATCC 61. Both of these standards are designed to assess how well a fabric retains its color when subjected to washing, but there are some key differences between the two that are important to understand.
ISO 105, also known as the International Organization for Standardization, is a global standard that is widely used in the textile industry. It is a comprehensive standard that covers a wide range of tests for color fastness, including washing, rubbing, and light exposure. The ISO 105 standard for color fastness to washing is known as ISO 105-C06, and it is used to evaluate the color change and staining of textiles after they have been washed.
On the other hand, AATCC 61, also known as the American Association of Textile Chemists and Colorists, is a standard that is primarily used in the United States. It is similar to ISO 105 in that it also assesses the color fastness of textiles to washing, but it uses a different test method. The AATCC 61 standard is known as the 2A test, and it is used to evaluate the color change and staining of textiles after they have been washed in a specific type of washing machine.
One of the main differences between ISO 105 and AATCC 61 is the way in which the tests are conducted. ISO 105 uses a standardized washing machine and a specific set of conditions, including temperature, detergent, and agitation, to simulate the washing process. AATCC 61, on the other hand, uses a different type of washing machine and a different set of conditions, which can result in different outcomes.
Another key difference between the two standards is the way in which the results are interpreted. ISO 105 uses a grading system to evaluate the color change and staining of textiles, with grades ranging from 1 to 5, with 5 being the best. AATCC 61, on the other hand, uses a different grading system, with grades ranging from 1 to 5 for color change and 1 to 3 for staining, with 5 and 3 being the best, respectively.
When interpreting the results of color fastness to washing tests, it is important to consider the differences between ISO 105 and AATCC 61. While both standards are designed to assess the same properties, the different test methods and grading systems can result in different outcomes. For example, a fabric that receives a grade of 4 on the ISO 105 test may not necessarily receive the same grade on the AATCC 61 test.
In conclusion, ISO 105 and AATCC 61 are two of the most commonly used standards for evaluating the color fastness of textiles to washing. While both standards are designed to assess the same properties, there are some key differences between the two, including the test methods and grading systems used. When interpreting the results of color fastness to washing tests, it is important to consider these differences in order to accurately assess the performance of a fabric.
Conclusion
The main differences between ISO 105 and AATCC 61 Color Fastness to Washing Standards are the test methods and conditions used to assess the color fastness of textiles. ISO 105 uses a variety of test methods depending on the type of textile and colorant, while AATCC 61 specifically uses the Launder-Ometer method. Additionally, ISO 105 includes a range of washing temperatures and times, whereas AATCC 61 primarily uses a standard temperature of 49°C and a time of 45 minutes. The two standards also differ in the type and amount of detergent used, as well as the use of steel balls or other abrasive materials during the test. Overall, while both standards aim to evaluate the color fastness of textiles during washing, they have different procedures and requirements that can lead to varying results.
