2.2.1
Essential Requirement 1: MECHANICAL RESISTANCE AND STABILITY
The staircase corresponds to the drawings and data contained in the annexes. The material
values, dimensions and tolerances of the components of the stair not indicated in the annexes
shall correspond to the values laid down in the technical documentation.
The staircase has a sufficient mechanical resistance and stability in order to resist static or
quasi-static loads.
The characteristic values of resistance of the staircase given in Annex 15 were determined
from loading tests and by structural analysis.
Prevention of progressive collapse
Failure of individual components of the staircase does not lead to a progressive collapse of
the complete staircase.
Residual load-bearing capacity
The steps loaded by service loads stated in Annex 15 have a sufficient residual load-bearing
capacity. A local material failure does not lead to an abrupt total loss of load-bearing capacity
of the steps.
Long-term behavior
Under appropriate use and maintenance conditions, the characteristic values of resistance
stated in Annex 15 will be ensured over the indicated working life.
Resistance to earthquakes
No Performance Determined (NPD).
Load/displacement behavior and vibration behavior
The characteristic values concerning the load/displacement behaviour were determined by
test and are given in Table 1.
The vibration behaviour was determined by test. Under a single load of 1 kN acting on the
most unfavourable point the staircase shows a deflection of w ≤ 5 mm. The first natural
frequency of the staircase (inclusive of a single mass of 100 kg) is greater than 5 Hz.

The ETA Holder may change, under his own responsibility, some of the suppliers of a component, but only provided that the
characteristics and the performances of the new components and the final performances of the system do not change at all. These
changes must be fully recorded within the Factory Production Control documents in order to grant full traceability.
