Steiner Tunnel Test. The steiner tunnel, which complies with ul 910, is used to measure flame travel distance and optical density of smoke for wires and cables and optical fiber cables. 0 10 20 30 40 50 60 70 01 2345 678 distance from burner (m) 2 heat flux (kw/m) fig.
Sgs farmingdale offers accredited fire and flammability testing, as well as physical textile tests, such as abrasion, colorfastness and strength to ensure th. Incident heat flux from the burner flame in the steiner tunnel test. In this method, specimens are placed on the ceiling of a 24 ft long tunnel.
In This Method, Specimens Are Placed On The Ceiling Of A 24 Ft Long Tunnel.
Specimens are set on the top of edge of the tunnel walls and are covered and enclosed by a single 25 foot refractory construction lid. The results of these tests provide comparative measurements of surface flame spread and smoke density. These standards are in widespread use for the regulation and selection of m…
The Steiner Tunnel Stays The Test Of Time.
An e84 test is conducted by placing a 24” wide x 24’ long sample into a steiner tunnel (see description of steiner tunnel below), wherein the test is administered through the use of two burners which provide 89kw of energy. Building codes and other documents then define and regulate. What is steiner tunnel test.
The Test Was Developed In 1944 By Al Steiner Of Underwriters Laboratories, And Has Been Incorporated As A Reference Into North American Standards For Materials Testing As Tests Astm E84, Nfpa255, Ul 723 And Ulc S102.
This method has been used for decades with success to assess the comparative surface burning characteristics of building materials for several decades. The steiner tunnel, which complies with ul 910, is used to measure flame travel distance and optical density of smoke for wires and cables and optical fiber cables. The test was developed in 1944 by al steiner of underwriters laboratories, and has been incorporated as a reference into north american.
All tested materials are subsequently compared to red oak for relative performance.

During the test, the sample is mounted on the ceiling under a removable lid, and a forced draft is provided in
The Astm E84 Test Specimen Is Conditioned To Equilibrium Moisture Content Which Is Determined By Weighing The Test Specimen.
The test provides for multiple specimens to be laid in the horizontal duct of the unit and burned for 20 minutes with an 87.9kw gas bunsen burner (300,000 btu/hr). Do watch the full video if u find the video informative like,share the video. The steiner tunnel test is a widely used method of testing building interior wall and ceiling finishes for their ability to support and propagate fire, and for their tendency to emit smoke.
