Register online for AATCC Proficiency Testing Programs

Posted October 21, 2021

RESEARCH TRIANGLE PARK, N.C. – Labs may now register online for all 2022 AATCC Proficiency Testing Programs (PTP).


The online registration process allows labs to complete registration and credit card payment in one easy step. Just add PTP registration(s) to your cart along with quality control materials, standards, and other items.

PTPs support certification and continuous improvement initiatives for textile laboratories. Compare results with hundreds of other labs to verify performance or identify areas for improvement.

Seven AATCC programs cover Antibacterial, Appearance & Physical Properties, Color Evaluation, Colorfastness, Fiber Analysis, Moisture Management and Resistance & Repellency test methods and evaluation procedures. Samples are selected to provide consistent results in a meaningful range for each program. Register now here.


How it works:

  • Labs register for one or more PTPs.

  • 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 distributes a report to participating labs with a confidential lab code.

  • Each lab receives a Certificate of Participation.
