Suspended ceilings - Requirements and test methods
The 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 (including, optionally, light fittings and other features), 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 standard.
In the absence of any other European Standard, this standard specifies dimensions, tolerances and, where relevant, performance requirements, for commonly available ceiling substructures and membrane components.
