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 at

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.
