SPECIFIC CONDITIONS OF THE EUROPEAN TECHNICAL APPROVAL
DEFINITION OF PRODUCT, INTENDED USE AND ASSUMED WORKING LIFE
The system is composed of a set of prefabricated components (steps, modules, railing
balusters, handrails, etc.) assembled together so as to form a winder staircase.
The steel load-bearing structure is manufactured in modules, named N21, one per step.
Each module, consisting of 2 parts and made of 4 mm steel plate and 3,2 mm thick steel tube,
is fastened to the adjacent modules by means of screws and nuts.
Modularity allows to adjust, within a given range, rise, tread, direction of rotation and height of
the staircases which can be straight, with one L curve or two U curves.
The kit includes bottom and top modules for the structural fixing of the staircase to the floor
and to the wall.
The kits also includes a ∅ 60X3 mm load-bearing metal post and two L brackets for the fixing
and further reinforcement of the staircase.
The 42 mm thick steps are made of beech wood obtained from solid wood panels and are
available in different colours.
Different railings and handrails according to the staircase version complete the kits.

CHARACTERISTICS OF PRODUCT AND METHODS OF VERIFICATION
2.1
General
This ETA is issued for stair kits “Arkè Kompact”, “Arkè Komoda”, “Pixima Long”, “Pixima
Long Line”, “Pixima Long Tube” on the basis of admitted information/data, deposited with ITCCNR, which identify the kit that was assessed and judged. Changes to the production process
of the kit or to the components of the kit which could result in deposited information/data
being incorrect, shall be notified to ITC-CNR before they are introduced and ITC-CNR will
assess whether or not such changes affect the ETA and, if so, whether further assessment
and/or alteration to the ETA shall be necessary7.
The characteristics of the components and of the system not mentioned in this ETA nor in the
Annexes shall correspond to the respective values laid down in the Technical Documentation
of this ETA, checked by ITC-CNR.
2.2
Methods of verification
The identification tests and the assessment of fitness for the intended use of “Arkè Kompact”,
“Arkè Komoda”, “Pixima Long”, “Pixima Long Line”, “Pixima Long Tube” were carried out in
compliance with ETAG 008-01.
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 12 were determined
from loading tests and by analysis based on experimental data.
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 12 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 12 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.
Deflection and proper oscillation frequency under load Q = 1 kN

Proof of ultimate limit state is only given if the design value of the loads (Fd) does not exceed the design value of the resistance (Rd): Fd ≤
Rd with Fd = Fk ⋅ γQ and Rd = Rk / γs
γs = partial safety factor of steel
γw = partial safety factor of wood
γQ = partial safety factor taking account of the model's uncertainties and dimensional variations (Appendix A of standard CEN/TS
15680:2007)
