Term	Definition
Durability class	What does durability class mean? Natural durability is divided into five classes according to the European standard EN 350. The abbreviation DC is often used for this. It stands for "Durability Class". The classification refers to the natural resistance of wood against wood-destroying fungi. In principle, this assessment is based on the heartwood. The sapwood of a wood species is generally much less resistant and is usually classified as non-durable against fungal attack. Synonyms - resistance class, durability class, resistance class, natural durability, durability classification, durability assessment
Drying kiln	Definition and Functionality A drying kiln is a closed, climate-regulated facility in which wood is dried by controlling temperature, humidity, and air circulation. The goal is to adjust the wood’s moisture content according to its intended use and to achieve a uniform moisture distribution throughout the entire cross-section. The drying process is controlled through the interplay of various physical processes, including the evaporation of free water from the cell lumina, the movement of water through cell walls, and the gradual reduction of the wood's overall moisture content. Modern drying kilns are equipped with sensors that monitor temperature and humidity, allowing precise control over the drying process and helping to prevent damage to the wood. Synonyms - drying chamber, Drying process, wood drying
