AATCC Proficiency Testing Programs

AATCC Proficiency Testing Programs (PTP) cover Antibacterial, AppearanceColor EvaluationColorfastness, Fiber Analysis, and Water Resistance test methods and evaluation procedures for textiles. Labs may register for any or all programs.

AATCC PTPs support lab certification and continuous improvement initiatives. Samples are selected to provide consistent results in a meaningful range for each test method or evaluation procedure.

Sample Shipment

Samples are shipped via FedEx. Your shipping address must include a contact name, complete street address (no PO boxes), and a phone number.

Samples are shipped approximately one month after the registration deadline for each round. Check www.aatcc.org/test/proficiency for registration deadlines.

Testing & Evaluation

Follow all testing instructions exactly.

Use the current version of all referenced Test Methods and Evaluation Procedures. Verify the current versions at www.aatcc.org/test/methods.

Use specified test equipment and materials. Check expiration and calibration dates.

Identify fabric face and warp/wale/machine direction of all specimens. Ensure proper testing orientation.

Minimize handling of fabric samples.

Online Data Entry

When testing is complete for each round, submit data through the Proficiency Testing Portal https://proficiency.aatcc.org.

Username and password for this portal is NOT the same as for placing orders.

Check data entry format (decimal places, etc.)

Review data before submitting. Outlier data may be excluded from analysis (e.g., 35 in place of 3.5).

Summary Report

AATCC compiles all submitted data in a summary report. The report is emailed approximately one month after the closing date for data submission.

Reports are emailed to the recipient address used to place the registration order. Please ensure this person knows to forward to others in the organization as needed. AATCC can release the report ONLY to the person who placed the order.
