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. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 520, Gypsum plasterboards - Definitions, requirements and test methods EN 13501-1, Fire classification of construction products and building elements – Part 1: Classification using test data from reaction to fire tests EN 13823, Reaction to fire tests for building products - Building products excluding floorings exposed to the thermal attack by a single burning item EN 14496, Gypsum based adhesives for thermal/acoustic insulation composite panels and plasterboards - Definitions, requirements and test methods 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 plasterboard cornice preformed paper covered gypsum section with profiled face supported by shoulders 3.2 face exposed surface usually concave, or partially concave with further contours to add embellishment 3.3 edge boundary between the face and back angle which defines thickness (AC, see Figure 1) 3.4 back angle return from edge, preset at a nominal 90° to facilitate positioning during application 3.5 end cut section of length

Figure 1 – Example of profile 4 Requirements 4.1 Reaction to fire Where subject to regulatory requirements, preformed plasterboard cornices shall be tested and classified in accordance with EN 13501-1. Preformed plasterboard cornices tested according to EN 13823 (SBI test) shall be mounted and fixed in accordance with Annex B or wfhen the producer wishes to claim performance for a specific intended use, the mounting and fixing shall be representative of that intended use. 4.2 Flexural strength (expressed as bending behaviour) Individual lengths shall be capable of being handled and installed using recommended practice. When tested in accordance with 5.4. the cornice shall not fracture. 4.3 Dangerous substances Materials used in products shall not release any dangerous substances in excess of the maximum permitted levels specified in a relevant European Standard for the material or permitted in the national regulations of the member state of destination. 4.4 Composition Preformed plasterboard cornices shall have constituents common to gypsum plasterboard to EN 520. 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.

4.5.3 Face The face and edges shall be free from bumps, grooves, voids, blisters, burrs, scuffing and staining. The distance ED shall lie within the tolerance limits of ± 1 mm when checked in accordance with 5.3.
a) minimum dimensions ("NOT GO")
b) maximum dimensions ("GO") Figure 2 — Silhouette template 4.5.4 Back angle The back angle (CXC) designed to facilitate positioning to the wall/ceiling angle shall be not less than 90° when checked in accordance with 5.3. 4.5.5 Side angle The side angle (DAC) shall be of the specified profile e.g. square, bevelled or rounded when checked in accordance with 5.3. 4.5.6 Face width The face width of the product (AA) shall lie within the tolerance limits of 2 mm when checked in accordance with 5.3.

5.2.2.2 Apparatus a) flat surface; b) metal rule permitting readings to 1,0 mm. 5.2.2.3 Procedure Place the specimen on the flat surface and measure the length. 5.2.2.4 Expression of results Record the measurements of the three specimens. All specimens shall comply with 4.5.8. 5.3 Determination of accuracy of profile 5.3.1 Principle The accuracy, symmetry and angles of the profile across its length shall be checked for each specimen. 5.3.2 Apparatus A rigid plastics or aluminium sheet cut to provide a template, comprising two silhouettes, of the end profile of the cornice design. One cut to the minimum and one cut to the maximum tolerance specification (see Figure 2). 5.3.3 Procedure Place the templates in turn over one end of the specimen and pull each along the length of the specimen to check its compliance with the specification of the profile, noting freedom from identifiable bumps and grooves on the exposed face CADAC. 5.3.4 Expression of results Record the results of the exercise on all three specimens. All specimens shall comply with the profile requirements in 4.5.2. 5.4 Determination of bending behaviour 5.4.1 Principle The ability of the full size specimen shall be established to resist fracture when flexed under its own mass.
5.4.2 Apparatus a) A balance with a capacity of 10 kg permitting readings to 1 g; b) a timer capable of measuring 5 min; c) two (25 ± 5) mm diameter cylindrical steel supports, minimum 200 mm in length placed horizontally and parallel with a means of securing at one end or both ends to allow them to be spaced 1,5 m apart. The position should also permit the testing of cornice of maximum length.

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.

All product characteristics in Clause 4 applicable to the intended uses shall be subject to initial type testing, with the following exceptions:  release of dangerous substances may be assessed indirectly by controlling the content of the substance concerned;  when design values are used. 6.2.3 Further type testing Whenever a change occurs in the preformed plasterboard cornices design, the raw material or supplier of the components, or the p
