What is the correct way to reference an AATCC standard?

Official designation for AATCC standards is AATCC TM/LP/EP/M#-YEAR.

AATCC TM8-2016

AATCC LP1-2018

AATCC EP9-2017

AATCC M4-2017

  • Include “AATCC” with all designations
  • Do not spell out “Test Method,” etc.—even on first use.
  • No space between letters (TM, etc.) and number.
  • Four-digit year.
  • Note: Beginning in 2020, you will see additional year formats in the Technical Manual. Any reference to a standard should include the full designation listed in the AATCC Technical Manual Manual.

How do AATCC standards compare to ISO standards?

Like AATCC, the International Organization for Standardization (ISO) publishes test methods for evaluating textile materials. In fact, many ISO colorfastness and water resistance tests are taken directly from AATCC test methods.

For more than 60 years, AATCC was the co-secretariat for ISO/TC38/SC1—Textiles—Tests for Coloured Textiles and Colourants and secretary for ISO/TC38/SC2—Textiles—Cleansing, finishing and water resistance tests. In 2010, AATCC transitioned these secretariats to other countries in order to focus on its own test methods and activities.

Although each country gets a single vote on ISO ballots, individuals may submit comments and opinions to be used in determining a country’s official position.

AATCC and ASTM International-Committee D13 Textiles are co-administrators of the Technical Advisory Group (TAG) representing the US in all TC38—Textile activities. To become a TAG expert and be consulted on ISO ballots, contact Erika Simmons.

What is the relationship between AATCC and ASTM?

ASTM International’s Committee D13 develops test methods and specifications for textile materials. In general, AATCC methods tend to focus on colorfastness, wet testing, and chemical analysis. ASTM tests evaluate physical properties of textiles.

AATCC and ASTM have published several joint Testing Supplements. These supplements are compilations of procedures and guidelines for textile products, not yet included in the official AATCC Technical Manual or Annual Book of ASTM Standards. Some are based on long standing industry practices or protocols developed by specific companies for in-house use.

AATCC/ASTM Technical Supplement

Moisture Management Technical Supplement

AATCC incorporates ASTM methods in most of its Test Method Training programs. You can also purchase the Textiles volumes (7.01 & 7.02) of the Annual Book of ASTM Standards from AATCC.

What is the AATCC Technical Supplement?

The AATCC Technical Supplement is a downloadable compilation of industry practices and guidelines for textile products. THESE ARE NOT OFFICIAL AATCC OR ASTM STANDARDS. The Technical Supplement is NOT current and has not been updated since publication in 2004. The documents are not official test methods and were not reviewed or approved by any committee.


If you wish to obtain this compilation, you may purchase the Technical Supplement at https://members.aatcc.org/store/supplement/255/. Please use these procedures with caution as they may contain incomplete or outdated instructions.

What is the shelf life of AATCC 1993 Standard Reference Powder Detergent?

AATCC 1993 Standard Reference Detergent should have an almost indefinite shelf life if stored in sealed containers. None of the components are prone to breakdown unless exposed to moisture. Three years is a reasonable estimate, but shelf life will depend on storage conditions. For this reason, the Certificate of Conformity does not include an expiration date.

Should I use AATCC Standard Reference Detergent with or without Optical Brightener to perform laundering tests (Applies to AATCC TM 88B, 88C, 124, 135, 143, 150)

These test methods should be performed with AATCC 1993 Standard Reference Detergent WITH optical brightener. A revision has just been approved to clarify this issue. The version that appears in the 2019 Mid-Year Supplement and the 2020 AATCC Technical Manual will specify detergent WITH brightener.



What are the different applications of the AATCC Standard Reference Detergents with or without Optical Brightener?

Detergent WITH brightener will provide appearance more like what consumers are likely to see at home—most consumer detergents include brighteners.

Detergent WITHOUT brightener will allow you to detect issues with dyestuffs because any color change is actually due to dye loss, not masked by brighteners.

How can I verify the UPF of a fabric or garment?

“How should I test my garment for UV protection?” It’s one of the most common questions asked of the staff of the AATCC Technical Center. It comes from fabric and garment producers, fiber and chemical companies, and even consumers.

There is also a renewed interest within the standards community about testing for UV protection. In 2017, the Australian/New Zealand standard was revised for the first time since it was published in 1996. AATCC and ASTM committees are currently working on revisions of their respective standards related to UV protection. The two organizations also jointly published ASTM and AATCC Technical Information and Standards for UV Protective Textiles to provide history, standards, and a testing flow chart in one convenient booklet.

What happened to L4 Blue Wool?

Use the 20 AFU & 5 AFU Blue Wool Lightfastness Standard (https://members.aatcc.org/store/bluewool/1665/)  to verify lightfastness and weathering testing. While modern lightfastness instruments have sophisticated means of measuring and controlling light energy, Blue Wool Standard specimens are still the best way to ensure proper exposure.

AATCC Blue Wool Lightfastness Standards have traditionally been referred to by an “L-designation.” The 20 AFU & 5 AFU Blue Wool Lightfastness Standard is technically an L2 fabric, but may also be used as a direct substitute for L4. Refer to instructions included in your purchase of 20 AFU & 5 AFU Blue Wool Lightfastness products (https://members.aatcc.org/store/bluewool/1665/), and appropriate test methods (https://members.aatcc.org/store/tm16-3/959/) for proper use of the standard.


Proficiency Testing Program

What is the AATCC Proficiency Testing Program?

AATCC Proficiency Testing Programs (PTPs) support lab certification and continuous improvement initiatives. Samples are selected to provide consistent results in a meaningful range for each test method or evaluation procedure. AATCC PTPs cover Antibacterial, Appearance, Color Evaluation, Colorfastness, Fiber Analysis, and Water Resistance evaluation procedures for textiles. To view the details of each program visit: https://www.aatcc.org/test/proficiency/

  • AATCC sends samples, instructions, and data sheets to participating labs twice per year.
  • Labs have approximately one month to complete testing and submit results online.
  • AATCC compiles results and distributes the report to participating labs with a confidential lab code.
  • AATCC issues digital Certificates of Participation at the end of the calendar year.

How do I register for the Proficiency Testing Program?

To view the details and register for the Proficiency Testing Program, visit https://www.aatcc.org/test/proficiency/#register. The registration deadlines for each program can be accessed by clicking on the respective tab via the link above.

Did my lab pass or fail the Proficiency Test?

AATCC does not supply satisfactory/unsatisfactory or pass/fail grades to proficiency programs. The sole purpose of the AATCC Proficiency Testing Programs is to provide a simple report showing laboratories how their own lab’s data looks in comparison to other labs’ data around the world performing the same tests using the same test specimens.

The data provided in the report is not to be interpreted as being right/wrong or satisfactory/unsatisfactory, it’s only to show a large data population and how your lab’s data fits within that large data population so that you can come to your own conclusions about your technicians’ testing and/or evaluating techniques.

Since the Proficiency Programs began in the early 2000’s, the staff have been upgrading and revising the data that is included in the results report. The current statistical format was developed by statisticians from the Institute of Textile Technology. The database structure that we use was created from their suggestions and expertise. The Introduction section of the report contains explanations of the statistics that appear with all report booklets.
