How is ASTM E84 testing performed?
The progress of the sample burning is observed through viewing windows installed on the side of the tunnel. A Light Obscuration meter is used to measure the optical density to determine smoke developed. Software records and computes a variety of data and generates the FSI and SDI. The FSI and SDI are used to establish a scale for the rate at which flame spreads and smoke develops during the ASTM E84 test. Based on the FSI and SDI a class rating is assigned to the material.

How to measure E84?
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. During the test, the sample is mounted on the ceiling under a removable lid , and a forced draft is provided in order for the movement of air and products of combustion within the tunnel, and to the exhaust/scrubber system. The progress of the flame is then monitored through viewports on one side of the apparatus and recorded, with software computing the various data points to derive the FSI and SDI. Smoke developed is also measured through the optical density of a light obscuration meter. It should be noted that the ‘fuel contributed’ measurement is no longer in use.
When is the E84 test required?
The 2006 International Building Code (IBC) specifies that “interior wall and ceiling finishes shall be classified in accordance with ASTM E84.” Additionally, the National Fire Protection Agency (NFPA) 101® Life Safety Code® requires that “Interior wall or ceiling finish that is required elsewhere in this Code to be Class A, Class B, or Class C shall be classified based on test results from NFPA 255, ASTM E-84, or UL 723.”
What is a Steiner Tunnel?
Developed by Albert Steiner in the 1940s, the Steiner Tunnel is a steel box lined on its sides and floor with fire brick and featuring a removable lid. The tunnel contains a 12-in. high fire chamber with two burners at one end providing 89kW of energy. The Steiner Tunnel was adopted as an ASTM Standard in 1950 and given the designation of E84. Equivalent standards are maintained by NFPA and UL as NFPA 255, UL 732, and with certain modifications as CAN/ ULC-S102. Under the Canadian standard, additional fire bricks are installed on the floor of the tunnel and the view glass is removed. UL 1256 also references a modified version of the Steiner Tunnel for use on certain roofing systems. The FSI and SDI indices are used to establish a scale for the rate at which flame spreads and smoke develops during an E84 test. For example, reinforced cement board calibration material has an FSI of 0 and an SDI of 0, whereas red oak calibration material has an FSI and SDI of 100.
Who does the E84 fire and smoke testing?
Intertek currently operates four testing laboratories within North America certified to perform ASTM E84 Testing. In addition, our Coquitlam, British Columbia lab specializes in conducting CAN/ULC-S102 testing for the Canadian market. Their services also include testing to IBC, NRCC, and NFPA 101 standards, as well as testing required by overseas nations and specialty groups such as the California State Fire Marshal and USCG. Intertek ’s Steiner Tunnels are some of the busiest in the commercial world.
Is E84 the same as fire rated?
No, E84 certifies the system does not exceed the FSI and SDI values after 30 minutes of fire. A fire-rated system can withstand one hour of fire resistance without exceeding the FSI SDI thresholds. The only temporary containment option that meets this threshold is drywall. There isn’t currently a modular containment solution that meets the fire-rated standards.

What is ASTM testing?
Established by the American Society for Testing and Materials, formally known as ASTM International, this evaluation measures a material’s reaction after being exposed to fire, in terms of flame development and smoke production. These testing standards let a customer know if a product has the potential to quickly cause catastrophic damage when exposed to an ignition source, compared to moderately withstanding ignition so that an attempt at extinguishment may be made. The amount of smoke and flame produced by a material is measured against two controls; fiber-reinforced cement board which does not burn or smoke, and red oak flooring, which represents a high flammability level.
Why is it important to test similar materials to the same standard?
However, testing similar materials to the same standard allows for fair performance comparisons to be made .
Is acoustical foam fireproof?
Despite continuing advances in technology and standards, there is no completely fireproof product and it is important to use products in a way that recognizes this fact. Open flames must always be kept away from acoustical foam or sound insulation, smoking should be avoided and areas with components generating extreme heat should not house acoustical foam installations. Always consult with building professionals and sound experts when planning to install acoustical foam.
