What You Need To Know About the Steiner Tunnel - UL723 / ASTM E84 – Recorded Webinar


Since the 1940s, the 25-foot test tunnel, known as the Steiner Tunnel, has been one of the prevailing “reaction to fire” test methods for assessing the surface burning characteristics of building materials. The regulation of rapid progression of fire on building materials, especially interior finish materials, is just as relevant today as it was 75 years ago.


This complimentary recorded webinar will provide an overview of the test Standards UL723 and ASTM E84 used to determine the important flame spread and smoke developed index ratings for building materials, used primarily within the US. We will examine the key differences between this method of tests and those used throughout Europe and Canada. We will also discuss how the applicability of this method is often confused with other fire response tests. Lastly, this presentation will discuss the significance of third party certifications and provide a review of UL’s online certifications directory to determine whether products comply with these Standards.


Upon completion of this webinar, participants will be able to:

  • Gain a better understanding of UL723 – Steiner Tunnel
  • Recognize the similarities and differences between the UL723 and ASTM E84
  • Recognize the differences between the UL723 (ASTM E84) and fire test methods used in Europe
  • Recognize the differences between the UL723 (ASTM E84) and fire test methods used in Canada (CAN/ULC S134)
  • Gain insight on the path to UL Certification and associated resources.
