Older unclassified doors in fire compartment boundary
The requirement in the building regulations for fire-rated apartment doors came in 1960, for 15 minutes of fire. When inspecting apartment buildings built in 1940-1959, SÄRF relatively often encounters original doors to the apartments. If it does not impose any preservation requirements, the principle has been to impose new fire-rated doors in a minimum class of EI 30-S₂₀₀, with the justification that apartment owners should be able to remain in their home for 60 minutes in the event of a fire at the neighbor’s, in accordance with government guidance1 regarding fire protection in apartment buildings.
