Just add PTP registrations for the remainder of 2023 to your online cart along with quality control materials, standards, and other items.

PTPs support certification and continuous improvement initiatives for textile laboratories. Samples are selected to provide consistent results in a meaningful range for each program. The programs allow participants compare results with hundreds of other labs to verify performance or identify areas for improvement.

  • AATCC sends samples, instructions, and data sheets
  • 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
