Fibre cement slates and fittings - Product specification and test methods
This document specifies the technical requirements and establishes methods of control and test as well as acceptance conditions for fibre-cement slates and their fibre-cement fittings for one or more of the following uses: - roofing, - internal wall finishes, - external wall and ceiling finishes. It applies to fibre-cement slates with a height dimension h (see Clause 4) not exceeding 850 mm for overlapping assembly. For the purpose of this standard, fibre-cement slates have been classified according to their bending moment. This document covers fibre-cement slates reinforced with fibres of different types as specified in 5.1.1. This standard does not include calculations with regard to works, design requirements, installation techniques, wind uplift or rain proofing of the installed products.

Foreword
This document (EN 492:2004/A2:2006) has been prepared by Technical Committee CEN/TC 128 “Roof
covering products for discontinuous laying and products for wall cladding”, the secretariat of which is held by
IBN/BIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by March 2007, and conflicting national standards shall be withdrawn at
the latest by June 2008.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

2.2 Modification 2
Add the following paragraphs:
"7.5.2.2.2 Mounting and fixing provisions for EN 13823
7.5.2.2.2.1 End use applications
The end uses covered by the standardised mounting and fixing are fibre cement slates and fittings used as
the external layer for discontinuously laid roof coverings, used as internal and external wall finishes and used
as external ceiling finishes. In these end uses, slates are fixed to timber battens or metal profiles with
mechanical devices in a pattern of double or single overlapping. The side of the slates directed away from the
fire is in contact with a ventilated cavity which is closed by either a rigid or flexible underlayer or a structural
wall or ceiling construction.
7.5.2.2.2.2 Test specimen
Products used for the construction of the test assembly are fibre cement slates with standard dimensions of
length, width and thickness. They are cut to size to accommodate the dimensions of the test assembly. They
include all facings and/or coatings that are normally applied to the product as it is placed on the market.
7.5.2.2.2.3 Test assembly
7.5.2.2.2.3.1 Dimensions
The test assembly is a corner set up made of two timber frame supporting constructions each, with a height of
1,5 m. One frame forms a long wing (1,0 m) the other frame forms a short wing (0,5 m). Further information is
given in Figures 4, 5, 6 and 7.
