27、land, Turkey and the United Kingdom. BS EN 14209:2017EN 14209:2017 (E) 4 Introduction Preformed plasterboard cornices are composed of gypsum plaster encased in and firmly bonded to strong durable paper liners in the shape of narrow lengths with various face profiles. The composition and finish is id

28、entical to that of gypsum plasterboard which makes them particularly suitable for use in situations where a compatible product is required to aesthetically enhance the junction between gypsum plasterboard lined or gypsum plastered walls and ceilings. As well as concealing unsightly cracks, they can

29、be used to provide a permanent and effective seal. They can also be used for decorative and acoustic purposes. Preformed plasterboard cornices are installed with gypsum adhesive or mechanically fixed and can be finished with direct surface decoration. BS EN 14209:2017EN 14209:2017 (E) 5 1 Scope This

30、 European Standard specifies the characteristics and performance of preformed plasterboard cornices intended to be used in building construction works either as part of the original specification or subsequently for improved decorative enrichment of the wall/ceiling angle in rooms. This standard cov

31、ers the performance characteristics: reaction to fire and flexural strength. This standard covers also 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. It provides the

32、 assessment and verification of constancy of performance of the products. This standard does not cover plain plaster and gypsum fibrous plasterwork cornices. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its
