AATCC Releases 2023 Proficiency Rounds

RESEARCH TRIANGLE PARK, NC — November 17, 2022 — Labs can now register for all 2023 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 first registration deadline is December 1 for the January Color Evaluation 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 Antibacterial, Appearance, Color Evaluation, Colorfastness, Fiber Analysis, Moisture Management and Water Resistance test methods and evaluation procedures. 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.
