Fire safety is paramount in chemical refineries, underground railway tunnels, electrical power substations, and offshore platforms. Understanding flammability classifications is critical when specifying composite structural components.
In this technical whitepaper by Rawji Exports (kumar), we explain how halogenated and intumescent additives enable FRP composites to achieve ASTM E84 Class 1 and BS 476 Part 7 Class 1 fire ratings.
1. Fire Test Standards Comparison
| Standard | Metric Measured | Rawji Exports Certified Rating |
|---|---|---|
| ASTM E84 | Flame Spread Index (FSI) & Smoke Developed Index (SDI) | Class 1 (FSI ≤ 25, SDI ≤ 50) |
| BS 476 Part 7 | Surface Spread of Flame | Class 1 (Zero surface flame propagation) |
| UL 94 | Vertical Burning Flame Extinguishment | V-0 (Self-extinguishing < 10 seconds) |
