Physical Testing Laboratory

The Dame S. Hamby Physical Testing Laboratory offers testing and analytical services for determining physical properties of fibers, yarns, fabrics, garments and other textile products. Testing is performed by experienced technicians in accordance with standard test procedures. The lab has the capability to perform a variety of American Society for Testing and Materials (ASTM), American Association of Textile Chemists and Colorists (AATCC) and other standards or, in many cases, to tailor a procedure to specific client needs.

Frequently Asked Questions

How do I initiate testing with the PTL?

  • Submit a ZTE Lab Work Request explaining your testing needs. This will generate a card into our project management system and a lab manager will contact you shorty.
  • A testing service order form (TSOF) must be completed before testing can begin, as required by the University. Once the lab manager understands your project, they will complete the form and send it to you for signature.
  • Information needed for a TSOF:
    • Name of the contact person who will sign the agreement
    • Company name and physical address (also mailing and billing addresses if different)
    • Phone, fax, and email of the contact person
    • The not-to-exceed dollar amount to be assigned to the TSOF*
  • *An open-ended TSOF with an open-ended dollar amount would allow you to send samples to us over an extended period-of-time on an as-needed basis for these tests or any other tests you may need. Open-end forms are typically effective for 3 years

Do you have a published price list?

No, but we offer a complimentary cost estimate tailored to clients’ requests.

What is the turnaround time for testing?

  • The turnaround time depends on existing test projects and the educational requirements of the lab.
  • Clients should generally allow for a two week turnaround time from the date the samples are received by the lab. The turnaround time also depends on the number of samples submitted and the tests requested.

What are the Physical Testing Lab’s lab conditions?

  • ASTM D1776 Standard
  • Standard temperature: 21+/- 2 degrees Celsius, 70 +/- 4 degrees Fahrenheit
  • Standard Humidity: 65% +/- 5
  • The lab does not have the capability to offer variation of conditions for humidity and temperature.

Can testing be expedited for an extra charge?

No, expedited service is not available due to educational priorities.

What are the sample preparation requirements?

Here in the PTL, we prefer to prepare the sample in house. We do require that clients provide identification of the technical front, technical back and warp or machine direction.

What are the test standards the PTL can perform?

  • The Physical Testing Lab performs ASTM and AATCC test standards.
  • In many cases the lab can tailor a standard to fit the needs of clients. The PTL has the capability to complete tests for other standards if requested by the client. There is an additional charge for this service.

Does the Physical Testing Lab offer consulting services?

  • The PTL staff does not offer consulting services. If consulting services are desired, you would need to contact a faculty member in the specific field of interest.
  • The PTL only provides a summary report and not an analysis of the data. It is up to the client to interpret the data.
