Abstract
The article investigates the charring and the char front temperature of beech, the most widespread hardwood species in Central Europe. The current Eurocode standard EN 1995-1-2 specifies the char front temperature to be 300 \(^{\circ }\)C, albeit this determination primarily applies to softwood species. Consequently, this article aims to examine whether this assumption applies to beech. Through advanced experimental analysis and numerical modelling, it was determined that the char front temperature for beech exceeds 300 \(^{\circ }\)C. This finding represents crucial information for the correct validation of fire-resistant design for structural elements made of beech. Moreover, it lays the groundwork for improving simplified methods of fire design, particularly for a more accurate determination of the charring depth.
