What is Steiner Tunnel Testing at Element?
Steiner Tunnel Testing measures the surface burning characteristics and smoke development of building materials under controlled fire conditions. At Element, we perform this test using recognized methods, including ASTM E84, UL 723, and CAN/ULC-S102/S102.2. Our facilities offer both ceiling-mounted and floor-mounted configurations to simulate real-world installation scenarios. This testing provides essential data on flame spread and smoke development, helping manufacturers meet safety regulations and achieve certification for their materials across global markets.

Key tests offered
Key tests offered
We provide comprehensive Steiner Tunnel Testing to assess flame spread and smoke development in building materials. We can test to global standards, including ASTM E84 and UL 723 (ceiling-mounted) and CAN/ULC-S102 (Canadian ceiling-mounted equivalent). For flooring or materials that melt and drip, we conduct CAN/ULC-S102.2 (floor-mounted). Our testing delivers precise, reliable data to validate performance claims, meet North American and international regulations, and accelerate market approval from development to final certification.
Methods and solutions offered
Methods and solutions offered
Our experts use controlled testing methods to evaluate the surface burning characteristics of building materials. These include precise measurements of flame spread and smoke development through advanced photocell measurement systems, providing accurate and repeatable results. By simulating actual fire scenarios, we help you understand how your materials will perform in real installations, ensuring they meet safety standards and regulatory requirements for building material certification and compliance documentation.
Cutting-edge equipment we use
Cutting-edge equipment we use
Our state-of-the-art testing facilities feature large-scale horizontal furnace chambers, where test specimens are either ceiling-mounted or floor-mounted depending on the test. These chambers are equipped with specialized gas burners and advanced photocell measurement systems. Built-in observation windows enable precise tracking of flame progression throughout testing. Every aspect of our equipment is calibrated to deliver accurate, repeatable results that meet the most stringent requirements for building material certification and compliance documentation.
Comprehensive fire testing solutions
Comprehensive fire testing solutions
In addition to Steiner Tunnel testing, Element offers a suite of supporting fire safety tests, including cone calorimetry and radiant panel testing. These tests provide deeper insight into factors such as heat release rate and surface ignition, helping you understand how your materials perform under various conditions. By combining these test results with Steiner Tunnel (Surface burning characteristics testing) results, we offer a more complete picture of your material’s reaction-to-fire performance, ensuring compliance.
