Bibliography

This European Standard specifies the terminology, requirements and test methods for factory made self-supporting metal sheets and tiles (for non-structural applications) delivered in the form of manufactured pieces for roofing and wall cladding and lining.This standard also covers ceiling (including internal metal sheet) and soffit applications and cassettes (see Figure 1).This standard covers self-supporting copper, zinc, steel, aluminium and stainless steel sheet with or without coatings, e.g. metallic, organic, inorganic or multi-layer (see Annex A). A moisture retaining layer may be present on the reverse side of the product. This standard also includes rules for marking, labelling and evaluation of conformity.This standard does not cover products for structural purposes, i.e. it does not cover products intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance to permanent static loads (excluding self-weight of the metal sheet).Requirements concerning acoustical and thermal insulation properties are not considered in this standard.This standard does not include calculation or design requirements with regards to the works, installation techniques or the performance of the installed products.
