Building components and structures can be classified according to their resistance to fire. The class or combinations of classes are usually followed by a number that indicates the time period for which the functional requirement applies.
Examples of classification are EI 30 which means that the structure is fire resistant (E) and insulating (I) for 30 minutes.
||Refers to the building element's ability to withstand fire on one or more sides, for a specified time and load without losing its stability.
||Is the ability of the building element to withstand fire on one side without the fire spreading to the other side of the element through leakage of flames or hot gases.
||Is the building element's ability to fire on one side maintain the temperature on the other side below a certain level.
||Is the ability of a building element to ensure that in a fire on one side the heat radiation does not exceed a certain level on the other side.
||Is the ability of a building element to withstand a mechanical shock.
||Applies to doors and sheep's ability to close automatically.
||Refers to the ability of a building element to reduce or eliminate leakage from one side to the other of gas and smoke.
||Fire protection (flame retardant cover)
||Refers to the ability of a cladding to protect the underlying material against, ignition, charcoal, etc. for a specified period of time.
