Fire protection & fire protection classes
Here you will find information about fire protection and fire protection classes for our fire doors and security doors.
Specifies integrity in minutes, protects against flames and through-breeze.
Specifies integrity and heat conduction in minutes. Max temperature rise 280/330C.
A maximum of 280 on average or a maximum of 330 on a single point. A-class door contains non-combustible material.
Specifies integrity and heat conduction in minutes. Max temeratur rise 140/180C.
A maximum of 140 on average or max 180 on a single point.
*Ei-class doors may be replaced with the corresponding A-class door, provided that it does not contain combustible material (BBR 5:6214).
Smoke density and fire resistance of the product
The fire test is carried out by the National Testing Institute (SP) where the product's fire resistance is subjected to a certain temperature influence, normally equivalent to a fire in a room. Fire resistance is one or more characteristics of the composite structure, e.g. a steel door and therefore not a feature of the materials involved. The design can then be classified in so-called fire technical classes.
Smoke and gas density Sa/Sm
Fire doors are normally classified as resistance to fire. To the fire classification, there can sometimes be a classification against smoke and gas. This is the door's ability to reduce possible leakage of smoke or gas from a fire. Smoke density of doors is designated by S and has two subclasses. So is the designation for smoke density at room temperature and Sm is designated for the density of smoke at 200 °C. These two classifications can be combined or classified separately.
