What is the peak heat release rate for a sofa made of polyurethane foam is approximately?

The peak heat release rate (PHRR) for a sofa made of polyurethane foam is typically around 300 to 400 kW/m². This value can vary based on the specific formulation of the foam and other materials used in the sofa's construction. Polyurethane foam is known for its rapid ignition and combustion properties, contributing to high heat release rates in fire scenariOS. It's essential to consider these characteristics when evaluating fire safety in upholstered furniture.
