Resistance
to fire is a characteristic of building elements and structures and
represents the time to
reach one of the
following boundary conditions:
- R- Loadbearing capacity;
- E- Integrity;
- I- Thermal insulation;
- W- radiation;
- M- Mechanical resistance;
- K- Cladding.
The
tests are carried out with standard fire impacts described in:
EN 1363-1 Fire
resistance tests - Part 1: General Requirements and
EN 1363-2:
Fire
resistance tests - Part 2: Alternative and additional procedures.
- Walls and partitions;
- Beams and columns;
- Suspended ceilings;
- Horizontal and vertical fire compartments;
- Floors and roofs;
- Fire dampers and ducts;
- Systems for protection of steel, timber and reinforced concrete elements;
- Penetrating and linear joint seals.
Fire tests based on the "fire resistance" characteristic of building elements and structures are given in the following table:
