3 Terms and definitions For the purposes of this document, the following terms and definitions apply: 3.1 stretched ceilings ceiling coverings comprising a continuous area obtained from one width or assembled widths kept under tension at its edges by a fastening system permitting dismantling and re-assembly These widths may be single or multi-layered sheets, coated fabrics or fabrics made up of coated yarn or monofilaments. Stretched ceilings may be perforated or not 3.2 product family total range of products within specific variability limits (defined by the manufacturer or a technical specification) of the product parameters and, if appropriate, of the final use parameters for which the specified safety characteristics do not change (do not deteriorate) This means that the test results obtained for one product in the family remain valid for all the products in the family 3.3 edge profile element fixed at the periphery of the ceiling to keep the ceiling stretched 3.4 anchoring device element connecting the stretched ceiling to the edge profile 4 Requirements relating to sheets and coated fabrics or fabrics made up of coated yarn or monofilaments 4.1 Essential requirements 4.1.1 Reaction to fire 4.1.1.1 Preparation and conditioning of test pieces The test pieces shall be conditioned prior to the test in accordance with EN 13238. 4.1.1.2 Ignitability test The ignitability test shall be carried out in accordance with EN ISO 11925-2. The flame shall be applied to the surface of the test piece fixed on the test piece holder by means of small pins incorporated in the surface of the U-shaped frame



EN 14716:2004 (E) 8 4.1.1.3 SBI "Single Burning Item" test Carry out the reaction to fire test in accordance with EN 13823. The stretched ceilings shall be tested perpendicularly in the test piece holder trolley for the SBI comprising one small wing (550 ± 5) mm × (1 500 ± 5) mm and one large wing (1 000 ± 5) mm × (1 500 ± 5) mm. a) In the case of single or multi-layered sheets, take 850 mm × 1 800 mm of the sheet to make the small
wing and 1 300 mm × 1 800 mm to make the large wing. Stretch the sheet in the transverse direction across a calcium silicate panel with a tensile force of 30 daN/m determined in accordance with EN ISO 527-3.
There shall be an air gap of 40 mm between the stretched ceiling and the substrate when assembling the ceiling. This air gap is obtained by means of a calcium silicate frame of desired thickness fixed to the perimeter of the substrate of the small and the large wing. The final configuration may be obtained by pinching the stretched ceiling at the back of the substrate by means of an aluminium track and a PVC ring. Adequate tension shall be applied to obtain a satisfactory degree of flatness and no creasing over the whole of the exposed surface (see Figure A.1 in Annex A). b) In the case of coated fabrics or those made of coated yarn or monofilaments, take a 1 500 mm × 1 500 mm test piece. Fix the test piece to a metallic frame (see Figures A.2, A.3 and A.4 in Annex A). This frame comprises an assembly of stainless steel tubes of rectangular cross-section forming two perpendicular wings, one small and one large. Attach the test piece to the peripheral members of the frame by means of the steel pins.
Prior to the test, the test piece shall be adequately stretched and flat so that no more that 30 % of the total exposed surface shrinks by more than 10 mm from the coplanar vertical plane at the back of the U-profile Then place the frame against the U-profile on the test piece holder trolley. To be representative of the final use, conduct the test with a ventilated space 80 mm wide at the back of the test piece in accordance with EN 13823. Attach two calcium silicate walls made up of one small wing of (580 ± 5) mm × (1 500 ± 5) mm and one large wing of (1 080 ± 5) mm × (1 500 ± 5) mm vertically 80 mm from the test piece. The sides furthest away from the angle and the spaces behind each wing shall be left open. 4.1.1.4 Requirements If the manufacturer wishes to make a declaration of the reaction to fire performance (i.e. if the stretched ceiling is subject to regulations), the stretched ceilings shall be subjected to the test and be classified in accordance with the requirements of EN 13501-1 and the resulting class shall be declared. If it is decided not to declare a reaction to fire performance, i.e. to place a product family on the market as a class F product, no test is required for this product family. 4.1.2 Release of other dangerous substances 4.1.2.1 Heavy metals and other elements 4.1.2.1.1 Requirements The migration of heavy metals and other elements, expressed in mg/kg of stretched ceiling, shall not exceed the values given in Table 1 (after correction as specified in 4.1.2.1.2) when measured in accordance with test A in EN 12149.



EN 14716:2004 (E) 9 If none of these substances is added during manufacture and if the raw materials are certified by the supplier as not containing these substances, the test is not necessary. 4.1.2.1.2 Interpretation of results The analytical results obtained in the tests specified in EN 12149 shall be corrected by subtracting the analytical correction factors given in Table 2 to obtain a corrected analytical result. The stretched ceilings are considered as satisfying the requirements of this document if the corrected analytical result is equal to or less than the limits indicated in Table 1. NOTE 1 Given the reliability of the methods specified in this EN 12149, it is necessary to use the corrected analytical results to take into account the results of the interlaboratory tests (see Annex D of EN 71-3). Example: analytical result for lead: 120 mg/kg. Corresponding analytical correction in Table 2: 30 %. Corrected analytical result = 120 - (120 × 30) / 100 = 120 - 36 = 84 mg/kg. This is considered to meet the requirements of the standard (lead: 90 mg/kg). NOTE 2 The measuring methods used in EN 12149 are derived directly from EN 71-3 on the safety of toys. Annex D of EN 71-3, in particular D.4 "Statistical uncertainty of the test procedure and interpretation of results", justifies the introduction of a correction factor.

If vinyl chloride or the products containing vinyl chloride are not added during manufacture and if the raw materials are certified by the supplier as containing less than 10 mg/kg of vinyl chloride, the test is not necessary.
