CEN/TC 177/WG 1 - Autoclaved aerated concrete components

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:
-   non-loadbearing 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 utilized, 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 document provides product category rules (PCR) guidance for the development of Type III environmental declarations for prefabricated reinforced components of autoclaved aerated concrete or lightweight aggregate concrete with open structure according to EN 15804.
This document defines the parameters to be reported, the EPD types (and life cycle stages) to be covered, the rules to be followed in order to generate life cycle inventories (LCI) and conduct life cycle impact assessments (LCIA) and the data quality to be used in the development of EPDs.
In addition to the common parts of EN 15804, this document provides guidance for elements made as prefabricated reinforced components of autoclaved aerated concrete or lightweight aggregate concrete with open structure:
-   defines the system boundaries;
-   defines the modelling and assessment of material-specific characteristics;
-   defines allocation procedures for multi-output processes along the production chain;
-   defines allocation procedures for reuse and recycling;
-   includes the rules for calculating the LCI and the LCIA underlying the EPD;
-   provides guidance/specific rules for the determination of the reference service life (RSL);
-   gives guidance on the establishment of default scenarios;
-   gives guidance on default functional units for elements.
This document is intended to be used for cradle to gate, cradle to gate with options or cradle to grave assessments, when the intention is clearly stated in the system boundary description.

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.
