EN 14209:2005 (E) 3 Foreword This European Standard (EN 14209:2005) has been prepared by Technical Committee CEN/TC 241 “Gypsum and gypsum based products”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the latest by August 2007. 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 EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14209:2005 (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 identical 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 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. Diagrams 1 and 2 show the relationship between this standard and the package of standards prepared to support the families of gypsum and ancillary products.

EN 14209:2005 (E) 6 1 Scope This 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 covers 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 for the evaluation of conformity of the product to this European standard. This standard does not cover plain plaster and gypsum fibrous plasterwork cornices. 2 Normative references The following referenced documents are indispensable for the application of this document.

The paper shall be suitable to receive decoration or be pre-finished. The abutting paper edges on the back of the cornice are, usually, concealed and secured by a self-adhesive paper tape. The core may contain additives, aggregates and/or fibres.

All specimens shall comply with 4.2. 6 Evaluation of conformity 6.1 General The compliance of preformed plasterboard cornices with the requirements of this standard and with the stated values (including classes) shall be demonstrated by:  initial type testing (ITT);  factory production control by the producer (FPC). For the purposes of testing, preformed plasterboard cornices may be grouped into families, where it is considered that the selected property is common to all preformed plasterboard cornices within that family. The decision on those products or properties which fall within a family shall be made by the producer. 6.2 Type testing 6.2.1 General Sampling and testing shall be in accordance with Clause 5. The results of all type tests shall be recorded and held by the producer for at least 5 years. 6.2.2 Initial type testing Initial type testing shall be performed to show conformity with this standard.
Initial type testing shall be performed at the beginning of the production of a new preformed plasterboard cornices type (unless it is a member of a family previously tested) or at the beginning of a new method of production (where this may affect the stated properties). Tests previously performed in accordance with the provisions of this standard (same product, same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account.
