Fibre-cement slates and fittings. Product specification and test methods
| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 52 |
This European Standard 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.
This European Standard 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 European Standard, fibre-cement slates have been classified according to their bending moment.
This European Standard covers fibre-cement slates reinforced with fibres of different types as specified in 5.1.1.
This European Standard does not include calculations with regard to works, design requirements, installation techniques, wind uplift or rain proofing of the installed products.
