ÖNORM EN 13964

This European Standard covers membranes, individual substructure components, substructure kits and suspended ceiling kits when these are placed on the market. This European Standard also gives certain specifications for the installed suspended ceiling system, for two reasons: the individual components and kits may have to meet certain requirements in order for the installed system to be able to meet the requirement when the system is installed, and because it is appropriate, for ease of reference, to give both component/kit requirement and installed system requirement in the same document, given the relationship between them. This European Standard provides information for the various parties responsible for designing, manufacturing and specifying/selecting suspended ceilings used for interior applications in general building and civil engineering structures. It covers suspended ceilings sold as a complete kit, substructures sold as kits, individual components (products) of such substructures, and membrane components. It includes test methods and methods of assessment, as well as provisions for the evaluation of conformity of the products to the requirements of this European Standard. In the absence of any other European Standard, this European Standard specifies dimensions, tolerances and, where relevant, performance requirements, for commonly available ceiling substructures and membrane components. This European Standard does not cover the following: ceiling substructures and membrane component covered by other harmonised European Standards, for in-situ formed ceilings, covered by other European technical specifications, for which it is the installer, not the component manufacturer, who takes responsibility for ensuring that the complete installed suspended ceiling meets any regulatory requirements to which it is subject; stretched ceilings covered by EN 14716; ceilings in mobile buildings, caravans and other forms of transportation; characteristics needed for special applications, for which additional characteristics other than covered by this European Standard would need to be complied with; ceilings subject to water penetration requirements; ceilings used externally where requirements other than covered by this scope would apply (tunnels, canopies, petrol stations, arcades, open sports facilities, car parks etc.); heavy duty suspended ceilings or their supporting construction (e.g. ceilings that can be walked on); ceilings made from fire protective boards covered by ETAG 018-4. This European Standards covers the following essential characteristics: reaction to fire; resistance to fire (suspended ceiling kits only); release of asbestos (content) (suspended ceiling kits and membrane components only); release of formaldehyde (suspended ceiling kits and membrane components only); shatter properties (for membrane components of brittle materials in suspended ceiling kits only); flexural tensile strength; EN 13964:2004 (E) + A1:2006 (E) 5 load bearing capacity; electrical safety; direct airborne sound insulation (suspended ceiling kits only); sound absorption (suspended ceiling kits and membrane components only); thermal conductivity (suspended ceiling kits and membrane components only); durability of flexural tensile strength and load bearing capacity against moisture; condensation. This European Standard also covers the following non-essential requirements: colour and light reflectance; installation.
