Yarn & Thread Performance Testing

The ASTM Proficiency Testing Program provides companies with a statistical quality assurance tool that enables them to compare, improve and maintain a high level of performance in the use of ASTM methods for yard and threads with other laboratories worldwide.

Conducted biannually, this program provides (for each test cycle) a hyperlink to record and submit test data, and instructions for conducting the tests.

Test samples include a spool containing 500 yards of a representative yarn/thread. 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.

For more information, contact us.

This program provides you with:

• The resources you need to satisfy proficiency testing elements of laboratory accreditation
• A useful quality control tool to monitor the strengths and weaknesses of laboratory performance
• Periodic comparison of test results and calculated statistical parameters with others in the textiles testing community worldwide
• A useful quality reference sample upon completion of testing

Each laboratory returns their completed test data to ASTM for use in generating statistical summary reports. Final reports, provided to participants only, contain:

• Coded laboratory test results
• Statistical analyses of test data
• Charts plotting test results versus laboratory code
• Histograms plus Box &s; Whisker Plots

Should you have an issue with your published results, please write to ptp@astm.org with your lab number and account number.

As a program participant, you will receive a spool containing 500 yards of a representative yarn/thread for testing, electronic interactive web based data report forms and test instructions for each test cycle. Your lab performs the test that you normally conduct within your facility using the specified ASTM program methods. Triplicate determinations by each lab are performed and statistics will be calculated on the average data submitted for each test by program participants.

Note: All program test parameters are subject to change but not without prior participant notification. Participation is NOT contingent on the performance of all program tests.

Test samples are prepared and distributed for ASTM International by SGS North America Deer Park, TX. under the Yarn & Thread 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:

• Ship through a third party shipping agent - Provide ASTM International with the complete contact information of a designated Shipping Agent located in the U.S. who will be responsible for shipping samples from the U.S. to your facility. Participants are responsible for making financial and shipping arrangements directly with the shipping agent.
  
   
  
  • Please be advised that when samples are shipped, an e-mail is sent only to the contact of record on your ASTM PTP account. It is the customer’s responsibility to advise their designated shipper that the sample has been shipped.
  
  
  • We cannot permit shipping agents to pick up samples at our distributors’ warehouses.
  
  
• Ship directly from the sample distributor via UPS, DHL, or FEDEX - Provide ASTM International with your shipping account number to cover shipping charges. Check that your carrier will deliver the test materials to your location. Materials classified as Hazardous may have restrictions.
  
   
  
  • You are responsible for additional fees charged-back to our distributor for any reason relative to your sample shipment including, but not limited to, fees for fuel surcharges, missing/invalid account numbers, dangerous goods, remote area delivery, and multiple delivery attempts.
  
  

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. Data submitted to Committee D13 from this ASTM-PTP Program are coded to maintain lab confidentiality.
