eldriftsvärde

Eldriftsvärde is a Swedish term that translates to "fire resistance value" or "fire performance rating". It is a classification used to describe how well a material or building component can withstand the effects of fire. This value is typically determined through standardized fire resistance tests conducted in accredited laboratories.

The eldriftsvärde is usually expressed in minutes and indicates the duration for which a material or assembly can maintain its structural integrity, prevent the passage of flames and hot gases, and provide thermal insulation when exposed to a fire. For example, a component with an eldriftsvärde of 30 means it can resist fire for at least 30 minutes.

Building codes and regulations in Sweden often specify minimum eldriftsvärde requirements for different parts of a building, depending on their function and location. These requirements are crucial for ensuring the safety of occupants by allowing time for evacuation and for the fire to be controlled. The testing procedures and classification systems for eldriftsvärde are governed by European standards, primarily EN 13501. Different classes, such as R (load-bearing capacity), E (integrity), and I (insulation), are used in conjunction with the time rating to provide a more detailed description of the fire performance. Understanding the eldriftsvärde is essential for architects, engineers, and builders to select appropriate materials and design safe structures.
