Steiner Tunnel Testing: reaction-to-fire testing on interior finish materials

A guide to understanding the Steiner Tunnel test and the differences between ASTM E84 and CAN/ULC-S102. 

Throughout the years, several regulatory bodies have incorporated the Steiner Tunnel test as their standard method to evaluate the fire performance of interior finish materials used in buildings.

In the U.S. and the Middle East, the Steiner Tunnel test is typically designated as ASTM E84, while in Canada it is widely known as CAN/ULC-S102. Although both tunnels run under the same operating conditions, the tests are different in many aspects.
