This European Standard specifies the characteristics and performance requirements for fibrous gypsum plaster cast-sections, rigid sheets, rigid tiles - made by various techniques in factories or workshops. This European Standard is applicable to:-conventional series produced products;-series produced products with varying properties ;-individual (and non-series) produced products, insofar required to be CE marked.See 4.1 and annex D concerning the classification of the fibrous gypsum plaster casts.This European Standard covers the following performance characteristics of the fibrous gypsum plaster casts : reaction to fire, thermal resistance, as well as resistance to impact by a hard steel ball and cohesion.The following performance characteristics are linked to systems assembled with fibrous gypsum plaster casts : fire resistance, impact resistance, direct airborne sound insulation, acoustic absorption to be measured according to the corresponding European test methods. If required, tests have to be done on assembled systems simulating the end use conditions.This European Standard defines the reference test methods for the technical specifications.This European Standard also covers additional technical characteristics of fibrous gypsum plaster casts that are of importance for use and acceptance of the products by the building industry and the reference tests for these characteristics.It provides for assessment of conformity of the products to this standard.This standard does not apply to:i) fibre reinforced gypsum sheet products (see pr EN 15283); ii) gypsum elements for suspended (see EN 14246);iii)solid casts; iv)run fibre reinforced products;v) plaster based stucco casts, carton pierre decors, resin decors; vi) moulds, models and mock-ups made of fibrous gypsum plaster;vii)fibrous gypsum plaster casts that, by nature, are not intended to be fastened in position;viii)fibrous gypsum plaster casts fo
