Slate and stone for discontinuous roofing and external cladding – Specifications for slate and carbonate slate
| Published By | Publication Date | Number of Pages |
| BSI | 2014 | 52 |
This European Standard specifies requirements for slate and carbonate slate for discontinuous roofing and external cladding, as defined in 3.1, and 3.2, used for assembly into discontinuous roofing and external cladding.
For the purposes of this European Standard, slates and carbonate slates have been classified.
This European Standard does not apply to products for roofing or external cladding made from the following:
-
stone other than those defined in 3.1 and 3.2;
-
concrete;
-
polymeric materials;
-
fibre reinforced cement;
-
metal;
-
clay.
This European Standard is not applicable to roofing and cladding slates used internally.
This European Standard is not applicable to bonded cladding (cladding fixed with adhesives) and cladding fixed with dowels and cramps.
Requirements for internal wall lining slate are specified in EN 1469 .
This document does not include requirements for appearance.
Some general guidance for appearance is given in Annex A.
This European Standard does not include installation rules for slates.
References to national recommendations on methods of construction for slate roofs are given in Annex C.
Where the term “slate” is used in this document it means slate and carbonate slate unless otherwise indicated.
