Proficiency Testing

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, Moisture Management, and Resistance evaluation procedures for textiles. To view the details of each program visit: www.aatcc.org/testing/proficiency/
  • AATCC sends samples, instructions, and data sheets to participating labs once or 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 www.aatcc.org/testing/proficiency. Registration deadlines are listed for each program, typically about one month before sample distribution.
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 2000s, 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. Click here to view and download a sample report.
What is included in the AATCC Proficiency Testing Program Summary Report?
  • AATCC compiles all submitted data in a summary report. The report is emailed approximately one month after the closing date for data submission.
  • Reports are emailed to the recipient address used to place the registration order. Please ensure this person knows to forward to others in the organization as needed. AATCC can release the report ONLY to the person who placed the order.
How do I submit data for the AATCC Proficiency Testing Program?
  • When testing is complete for each round, enter all data in the provided spreadsheet. Save with your lab code as the file name and email to ptp@aatcc.org.
  • Completed spreadsheet must be received by the submission deadline to be included in the report.
  • Review data before submitting. Outlier data may be excluded from analysis (e.g., 35 in place of 3.5).
When and how are samples shipped for the AATCC Proficiency Testing Program?
Samples are shipped via FedEx. Your shipping address must include a contact name, complete street address (no PO boxes), and a phone number.

What is the correct way to reference an AATCC standard?
The official designation for AATCC standards is AATCC TM/LP/EP/M#-YEAR.
  • 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.
Examples:
  • AATCC TM8-2016
  • AATCC LP1-2018
  • AATCC EP9-2017
  • AATCC M4-2017
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.
Can I resell AATCC Test Methods and Publications?
You may resell AATCC products as long as you do not change the number of licenses—for example, you may purchase and resell a USB containing the Technical Manual, but you may not create additional copies to sell. AATCC does not have licensed or approved resellers. Use of the AATCC logo is carefully restricted. The AATCC logo may not be added to any item or packaging. The AATCC logo may only be used for marketing purposes in compliance with the corporate member policies—to highlight AATCC membership, but not to imply endorsement by AATCC.

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?
Please see the most up-to-date version of the specific AATCC Test Method in the AATCC Technical Manual and reference your customer's agreed-upon specifications for instructions.
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 is AATCC’s UV Calibration program?
AATCC’s UV Calibration program is designed to help users calibrate their spectrophotometers to properly measure optically brightened specimens and improve consistency and agreement among instruments. Subscriptions last for one year and subscribers receive two optically brightened textile standards; one within three weeks of purchasing a subscription and another six months later. For more information, visit www.aatcc.org/testing/uv/.
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.
