This European Standard specifies the characteristics of metal framing components intended to be used in building construction works in conjunction with gypsum plasterboard conforming to prEN 520 where the assembly is non-loadbearing. These include, for example, partitions, wall and ceiling linings and the cladding of beams, columns, ducts and lift shafts. It covers the following performance characteristics : reaction to fire, flexural (yield) strength to be measured according to the corresponding European test methods. It defines the reference test methods for technical specifications. It provides for the evaluation of conformity of the product to this European Standard. This EN also covers additional technical characteristics that are of importance for the use and acceptance of the product by the construction industry and the reference tests for these characteristics. A method of designation has been incorporated to cover the multiplicity of metal sections currently in use, without recourse to a means of rationalisation of their shape, profile or dimensions. This standard does not cover load-bearing steel framing components.
