This program is accredited in accordance with the recognized International Standard ISO/IEC 17043: 2010 Conformity Assessment - General Requirements for Proficiency Testing, by the American Association for Laboratory Accreditation. Certificate Number: 4209.01
Why Should Your Laboratory Participate?
ASTM's Proficiency Test Program for Knit Fabrics provides participating laboratories with a statistical quality assurance (SQA) tool, enabling them to compare their performance in the use of ASTM methods for knit fabrics against other laboratories worldwide.
Conducted biannually, this program provides (for each test cycle) three test samples, a hyperlink to record and submit test data, and instructions for conducting the tests.
Test samples include three types of knit fabrics. Laboratories are instructed to conduct the tests in their facilities using the ASTM methods cited in the program (or other methods used by the lab) and to record their test results on the interactive form.
Each laboratory electronically submits their test data to ASTM for use in generating statistical summary reports. ASTM handles all data on a strictly confidential basis with no disclosure of lab identity except for one's own laboratory. Final reports contain all laboratory test data (coded), statistical analysis of test data, charts plotting test results versus lab code, and other information.

Participation does not require performance of all tests.
Test samples are prepared and distributed for ASTM International by WKF America in WFK America/ Phoenix Business Solutions, LLC in Rocky Hill, SC in under the Knit Fabrics program. Program fees do not include the cost of shipping the test samples to international participants (see below).
IMPORTANT for International participants: You have the following options for receipt of samples:
This program provides you with:
Each laboratory returns their completed test data to ASTM for use in generating statistical summary reports. Final reports, provided to participants only, contain:
Should you have an issue with your published results, please write to email@example.com with your lab number and account number.
Three yards of each fabric type are used in the program for each test cycle
Participation is on an annual fee basis and open to all laboratories. Registration fees must be paid in advance to participate. Testing must be performed within the participant's laboratory facilities. A laboratory does not need to perform all the program tests to participate.
Committee D13 on Textiles, consisting of over 500 members, and developer of over 300 standards, provides the technical direction for the program. Test information generated in the program is utilized by Committee D13 to determine if modifications to ASTM documents or new standards are warranted.
