Labs can now register for all 2024 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. Register now to avoid the rush. The next registration deadline is March 15 for the April Antibacterial Properties round!

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 test methods and evaluation procedures for Antibacterial Properties, Appearance, Color Evaluation, Colorfastness, Fiber Analysis, Moisture Management, and Water Resistance. Samples are selected to provide consistent results in a meaningful range for each program.

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 by email.
  • AATCC distributes a report to participating labs with a confidential lab code.
  • Each lab receives a Certificate of Participation.

What’s New

Each program will be offered only once during the calendar year. The timing for several programs has also shifted. A complete schedule is posted online.

The registration and payment deadline for all PTPs is extended to the 15th of the month prior to sample distribution. No registrations can be accepted after the deadline to ensure fair and timely processing for all participants.

Watch for new data sheets and streamlined reports throughout the year. AATCC is constantly working to make PTPs more useful and valuable to participants.
