Register for 2024 PTP Rounds
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.
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.
