This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the
22、latest by January 2018, and conflicting national standards shall be withdrawn at the latest by April 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent ri
23、ghts. This document supersedes EN 14209:2005. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of Regulation (EU) No. 305/2011. For relationship with Regulation (EU) No. 305/2011, see
24、informative Annex ZA, which is an integral part of this document. The main technical changes that have been made in this new edition of EN 14209 are the following: a) normative references have been updated; b) new clause symbols and abbreviations has been introduced; c) Annex ZA and Clause 6 have be

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
