What is the fire resistance rating of the materials used in the table?

The fire resistance rating of a material indicates its ability to withstand fire and prevent its spread. For tables, this rating is not typically a single universal value but is determined by the specific materials used in their construction and whether they have undergone standardized fire testing.

Common table materials like solid wood, engineered wood (plywood, MDF), metals, and plastics have inherent but varying reactions to fire. Solid wood chars, which can insulate the underlying material, while some treated engineered woods or fire-retardant plastics may be designed to self-extinguish. Metals like steel and aluminum do not burn but can warp and lose structural integrity at high temperatures.

Official fire resistance ratings come from standardized tests conducted by organizations like ASTM International or Underwriters Laboratories (UL). A common standard is ASTM E84, which measures the surface burning characteristics, resulting in a Flame Spread Index and Smoke Developed Index. Materials may be classified as Class A, B, or C based on this index. Another key standard is UL 94 for plastic materials, rating them as HB, V-0, V-1, or V-2 based on how quickly they stop burning.

For commercial or public use, tables must often comply with local building and fire codes, such as the International Building Code (IBC), which may mandate specific flame spread ratings. Residential furniture may not have a mandated rating unless specified.

Therefore, to know the fire resistance rating of your specific table, you must consult the manufacturer's technical data sheet or safety certifications. Look for labels indicating compliance with standards like ASTM E84, UL 94, or CAL 117 (for upholstery). For high-risk environments, specifying furniture with certified fire-retardant materials is crucial for safety.
