(Amendment)Prefabricated reinforced components of autoclaved aerated concrete
Prefabricated reinforced components of autoclaved aerated concrete
This European Standard is for prefabricated reinforced components of autoclaved aerated concrete to be used in building construction for: a) Structural elements: - loadbearing wall components; - retaining wall components; - roof components; - floor components; - linear components (beams and piers). b) Non-structural elements: - nonloadbearing wall components (partition walls); - cladding components (without fixtures) intended to be used for external facades of buildings; - small box culverts used to form channels for the enclosure of services; - components for noise barriers. Depending on the type and intended use of elements for which the components are utilised, the components can be applied - in addition to their loadbearing and encasing function - for purposes of fire resistance, sound insulation and thermal insulation indicated in the relevant clauses of this European Standard. Components covered by this standard are only intended to be subjected to predominantly non-dynamic actions, unless special measures are introduced in the relevant clauses of this European Standard. The term "reinforced" relates to reinforcement used for both structural and non-structural purposes. This European Standard does not cover: - rules for the application of these components in structures; - joints (except their strength and integrity E of resistance to fire); - fixtures; - finishes for external components, such as tiling. NOTE AAC components may be used in noise barriers if they are designed to fulfil also the requirements of EN 14388.

This steel number needs corrosion protection the efficiency of which is verified in accordance with EN 990, see 5.3.3.
The performance characteristics of stainless steel are defined in EN 10088-5 and shall be tested in
accordance with the test methods of that European Standard with the following exceptions and additional
performance characteristics when used for reinforcing of AAC components:
1) Characteristic values for mechanical properties of stainless reinforcing steel
Tensile strength values of stainless reinforcing steel shall be declared as characteristic values defined as
the 5% fractile of that property (p=0,95) at a confidence level γ = 90%. When calculating strength values,
nominal cross-section area of the product is used. This definition refers to the long term quality level of
production.
2) Suitability for bending
When bent stainless reinforcing steel is used its suitability for bending shall be determined by the bend
test according to EN ISO 15630-1, with a minimum angle of bend of 180°. After testing the products shall
not show rupture or visible cracks. The mandrel diameter specified for the bend test shall not exceed the
relevant maximum diameter specified in Table 5b.
NOTE 2 The absence of cracks visible to a person with normal or corrected vision is considered as evidence that
the test piece withstood the bend test. A superficial ductile tear can occur at the base of the ribs or indentations and is
not considered to be a failure. The tear can be considered superficial when the depth of the tear is not greater than
the width of the tear.

Where the same material is used in a range of components, it is only necessary to test the material for one type of
component.
g
Only if declared on the basis of a measured value.
h
Only relevant in case of multilayer components.
i
Reaction to fire test is only necessary if the content of organic material is higher than 1 % by mass or volume (whichever is
higher).
j
According to test method valid at the place of use of the component.
k Only if required (see Table 8).
