Introduction to Fiberglass Handrails and Fencing
Fire safety is a top priority in the construction sector. One of the primary standards for assessing the fire-resistant qualities of construction materials is ASTM E84, also known as the “Standard Test Method for Surface Burning Characteristics of Building Materials.”
Understanding ASTM E84
ASTM E84, often referred to as the Steiner Tunnel Test, is a standardized testing procedure created by ASTM International. It evaluates the surface burning characteristics of building materials, focusing on two key aspects: flame spread and smoke production.
In the ASTM E84 test, a sample material is placed in a horizontal tunnel-like chamber and subjected to a controlled flame. This test evaluates two crucial parameters:
Flame Spread Index (FSI): This index measures how fast the flame spreads over the surface of the sample. A lower FSI indicates higher fire resistance.
Smoke Developed Index (SDI): This index gauges the amount of smoke produced when the material burns. Lower SDI values are desirable as they suggest minimal smoke generation in a fire.
The ASTM E84 standard is widely cited in global building codes and fire safety regulations, helping ensure that construction materials comply with essential fire performance standards.
The Significance of ASTM E84 for FRP Gratings
FRP (Fiber Reinforced Polymer) gratings are widely used in various construction settings, such as walkways, platforms, and stairways. They are favored for their advantages, including resistance to corrosion, lightweight nature, and slip-resistant surfaces.
However, for FRP gratings to be deemed suitable for many construction projects, they must conform to the ASTM E84 standard for surface burning characteristics. This compliance is vital to maintain the fire safety integrity of any building or structure.
FRP gratings that meet the ASTM E84 standard have demonstrated low flame spread and smoke production, making them a safer option in environments with high foot traffic or potential fire risks. When FRP gratings meet this standard, they can be specified and installed with confidence, offering both functionality and enhanced fire resistance for construction projects.
Adherence to ASTM E84 is particularly important for FRP gratings used in:
- Commercial and industrial facilities
- Hospitals and healthcare settings
- Educational institutions
- Transportation hubs (such as airports and train stations)
- Offshore and marine environments
By choosing FRP gratings that comply with ASTM E84, construction professionals ensure their projects meet safety codes and protect occupants in case of a fire.
Conclusion
ASTM E84 is a fundamental standard for assessing the fire safety of building materials, including FRP gratings. When FRP gratings adhere to this standard, they can be safely specified and installed, delivering both practical use and fire safety. Meeting ASTM E84 requirements is crucial for ensuring the safety and durability of buildings and infrastructure.

Frequently Asked Question
ASTM E84, also known as the Steiner Tunnel Test, is a standard test method used to measure the surface burning characteristics of building materials. For FRP gratings, compliance with ASTM E84 is important to ensure they have low flame spread and smoke development, enhancing fire safety in construction applications.
The ASTM E84 test measures two critical parameters: the Flame Spread Index (FSI) and the Smoke Developed Index (SDI). FSI indicates how quickly flames spread across a material’s surface, while SDI measures the amount of smoke generated. Lower values in both indexes indicate better fire-resistant properties.
Not all FRP gratings are ASTM E84 compliant. It is essential to verify that the FRP gratings you select have been tested and meet the ASTM E84 standard to ensure they provide adequate fire resistance and meet local building codes and regulations.
ASTM E84-compliant FRP gratings are commonly used in areas that require high fire safety standards, such as commercial and industrial buildings, hospitals, educational institutions, transportation hubs, and offshore or marine environments. Compliance ensures the materials contribute to a safer environment in case of a fire.
