EN 12602:2008/FprA1
(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.

Foreword
This document (EN 12602:2008/FprA1:2012) has been prepared by Technical Committee CEN/TC 177

3 Modification to 4.1.2
Replace the content of the subclause with the following text:
"National regulations on dangerous substances may require verification and declaration on release, and
sometimes content, when construction products covered by this standard are placed on those markets.
In the absence of European harmonised test methods, verification and declaration on release/content should
be done taking into account national provisions in the place of use.
NOTE An informative database covering European and national provisions on dangerous substances is available at
the Construction web site on EUROPA accessed through http://ec.europa.eu/enterprise/construction/cpd-ds/.".

alternatively as a value taking the total value of drying shrinkage ε multiplied by a reduction factor 0,5."
cs,tot
with “The shrinkage class as specified in Table 2b shall be declared based on the mean conventional
reference value ε or alternatively based on a value taking the total value of drying shrinkage ε

6 Modifications to 4.3.1
Replace the existing sentence with the following text:
"The reinforcement consists of reinforcement steel made by smooth bars or de-coiled products according to
EN 10080 or stainless steel according to EN 10088-5.
Unless specified by a harmonised product standard, it shall be demonstrated that the reinforcement
purchased from the steel works to be used in prefabricated reinforced components of autoclaved aerated
concrete has been subject to an initial type testing, audit testing of samples taken at the factory, initial
inspection of the FPC and continuous surveillance of the FPC.
NOTE 1 Appropriate certificate will demonstrate how the manufacturing of reinforcing steel is subject to third party
control covering initial type testing, audit testing of samples taken at the factory, initial inspection of the FPC and
continuous surveillance of the FPC.
Unless specified by a harmonised product standard for structural stainless reinforcing steel, it shall have a
diameter not greater than 12 mm.
Declared strength and ductility properties of reinforcing steel used in AAC components shall comply with the
properties of steel after straightening and after autoclaving.
NOTE 2 Thermal elongation for austenitic stainless steel is higher than for normal steel and ferritic or austenitic ferritic
stainless steel.".
7 Modifications to 4.3.2
st
Add the following text after the 1 paragraph:
"Table 5a together with EN 10088-5 gives the applicable stainless steel grades, their chemical composition
and density.
Electrical resistance welding shall be used when connecting stainless steel bars and de-coiled products.
NOTE 1 Corrosion protection layer is often needed also with stainless reinforcing bars and de-coiled products due to
autoclaving process.
